Laserjet P2015 displays Paper jam and Toner lights

I have a Laserjet P2015DN that is showing a strange series of lights, both the Paper Jam :/\\/ and Cartridge -|_|- lights are both lit. When I do a cold reset, it cleared once but would not print. Reset it again, and the Paper says it out or it goes back to Jam/Toner lights. Sounds like a sensor but I can not find an Engine test to try this out.

Any help will be greatly appreciated.
Awhile back I started this thread and thank all of you for your feedback. After second board with a faulty network port, we hit the third time and the formatter is being replaced in this same printer. HP says the next one will be a replacement printer for this one lemon. Wish me luck as I try telling HP to upgraded this lemon to a better printer because of all the downtime it has had. Three repairs in 6 months and it has 29 months of warranty on it. HP needs to re-eval this product.

In answer to the recent question about where P2015 formatter boards can be purchased and how much they cost. HP appears to have been sold out for the past several weeks and no longer even lists a price in their HP parts store for some reason. I suspect that's verification of the suspicion that many people have that a lot of these boards have failed. Otherwise, they would not be sold out. HP will probably make more to fill the spare parts demand, but that can take months sometimes. In the meantime The Printer Works currently has plenty in stock of both the network (Q7805-60002) and non-network (Q7804-60001) versions. Prices vary by customer account, but are currently about $100 each. Additionally, there are several posted on eBay as well for similar prices.

My P2015dn started with the paper sensor saying there was no paper when there was. Then it progressed to no response on the network port and then it switched to the paper jam light being on with no paper jammed.

I pre-heated the oven to 375°F and then set it to 350°F when I put the formatter board in for 8 min. I put the printer back together, and it is working again, for now. I'll check back in in a month or two with an update on how the fix is lasting.

This model has experienced a lot of formatter board problems. The cause is the use of the newer lead-free solder that can't take the heat of the ic chips. If you scroll down the thread, you'll see where many people have had success using my suggestion of baking the formatter boards in an oven. There are a lot of tips on temperature and methodology.

My machine had same problems, would not start up and lights were on, as in this forum, i concluded it was the formatter board, because i did print a test sheet (secret button under and in front of formatter board) and the machine worked - just not the board..... and being that it would not make a difference cuaase it was already broken, I baked it - preheated 350 on three bals of foil, chips up and plastic off... and i cant believe I am saying to you now that... It worked.,! Thank you fixyourownprinter forum! Dave - abq, nm - unknown
I have a printer that came in for warranty service with this exact problem today. After finding that this error code is not listed in the service manual, I tried doing a cold reset, and then an NVRAM reset. Neither process worked properly, so I called HP. They immediatly informed me that if it wouldn't take either of those resets then it would definetly be the formatter board (Q7804-60001 for the standard base version of the Laserjet P2015), and it's apparently a known issue on there end.

To do a Cold Reset:
1. Turn off the printer.
2. Press and hold the Go button.
3. Turn the printer on, and continue to hold the Go button for at least 5 seconds, but not longer
than 15 seconds. During this process, the Attention LED turns on.
4. Release the Go button.

To do an NVRAM Reset:
CAUTION Only perform the following procedure if absolutely necessary. Performing an
NVRAM initialization resets some parameters that cannot be restored later.
NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a
default ROM value, depending on the variable. It also performs a system reset.
NVRAM initialization resets the following:
�œ All menu settings to factory default values
�œ Factory settings such as formatter number, page counts, and factory paper settings
Use the following procedure to perform an NVRAM initialization.
1. Turn the printer off.
2. Press and hold down the Go button.
3. Turn the printer on, and continue to hold the Go button for at least 20 seconds. During this
process, the Go button, Attention, and Ready LEDs each turn on.
4. Release the Go button.
The printer lights begin cycling. After the NVRAM initialization is complete, the printer returns to the
ready state.

I'm an ASP and I've seen several of these come into our shop and the formatter fixed it each time.
When this machine boots normally, the jam light should come on, then the toner light, then the add paper light and if I remember correctly after that they all cycle once or twice then goes ready. If the lights don't go thru this sequence the board isn't booting correctly and needs replaced.

I've just seen this now first hand yesterday, now a cold reset did fix it, all I had to do was get back into a computer & reconfigure the network settings.

I think I got lucky though, I did see the Event log on the first configuration page listing a lot of 49.xxxx errors. The thing is I went out to see if they had an updated firmware on the website & so far there isn't one. My guess is that code means a 49 error as thats all that the event log had listed on this machine.

If the error returns I'll be ready to get the formatter (although it might be take time to find one). It'll be the 3rd machine we had to put a board into for this customer (they got a few branch locations with these models). One machine we had to get HP to send a replacement because the formatter was on a 1+ month backorder.

Hello All, I'm a HP ASP and I'm factory certified on this machine. I have seen a rash of these machines with this problem lately. We have replaced formatters without any success. We will be swapping parts on machines this week to isolate the problem. I will keep everyong posted. I can only say this, "Every since HP switched to China from Japan" for production, nothing but poor quality and problems....

Do you know the commands to reset the Formatter Number and Product Serial Number? I just replaced a formatter board in an HP LaserJet P2015dn and can't find the command set to reset the values on this printer anywhere. Thanks. Erin - Anonymous
Miller U r very right. Things have really changed, as when it comes to quality. I have a HP G85 printer quite old but will never compare with what is available this days. Men its very disapointing to see how clients r spending so much cash yet the products we get this days r not reliable. If only Japan can take over again. Am a Tech in Kenya, repairing printers and laptops but I tell U my workshop is full of brand new junks. - Anonymous
Hi all, I have one of these printers with nearly the exact same problem. The difference is that _only_ the paper jam light is illuminated. The engine test prints perfectly. The printer won't at all respond to the cold reset and NVRAM reset procedures (nothing happens, and no more lights illuminate).

And, btw, I'm not an ASP or anything, just a home user. Does HP usually send replacement parts directly to customers?

Thanks in advance,

Yes Carlb they do as far as I know, the HP # to call for parts is 1-800-227-8164 & the formatter is what you need to replace if the engine test printed but nothing else will print.

Part # is:

Q7804-60001 for Base Models (NO Network port)
Q7805-60002 for Network Models

The parts are still New outright, so no exchanges right now on them. I'm showing a list price of $97.85US for either, not sure if thats correct though. (Shipping would be extra, only options they give me is ground or overnight)
by Sharpie on Apr 2, 2008 at 1:12pm Add comment
Yeah the 0 just means you not being charged extra for a core return, exchanges would have an amount there that would be refunded or charged if the core isn't returned.

You can try & use this link for warranty check

If it does say its out then you'll need a receipt showing its not been a year yet.

I haven't ever tried installing a networked formatter in a base model, I'd imagine it would convert it just fine though, not positive.

Had the same problem, paper jam lights, no network and no usb activity. New formatter fixed the issue, but trying to program the serial number in the new formatter turned into a huge hassle that I could never resolve. From HP's support forums there is supposed to be a way to send the serial number the same way you would a firmware file via FTP or LTP, but time constrants stopped me from getting it done.

I just spoke to HP and they had me run one more test to reset the formater board. To reset the formater board: turn off the machine, turn on the machine while holding down the green button. Hold the green button for at least one minute but not more than one minute 15 seconds. If this reset does not fix the problem, HP said the formater board needs to be replaced.
by unknown on Dec 15, 2008 at 8:47am Add comment
The engine test button should be on the left side below and to the right of the formatter. You will have to remove the left side cover. This post if for another issue though with both lights lighting up. A engine test will probably just not print verifying your problem is still a jam issue.
by nivek on Dec 15, 2008 at 2:53pm Add comment
Generally if you have a paper jam and you open then shut the toner access door the main motor will not turn, if the motor turns then look for a some othe problem. (toner)

My question before I rage against the system...

Any specific advice on installing the formatter board would be appreciated. I'm assuming the board is what I see when I open the little 3x5 inch hatch in the center of the left side of the machine. Can you remove and refit the board using only this hatch or do you have to remove the side panel for full access? If so advice on cracking the case without damage would be appreciated.

After seeing trouble lights with no evidence of the problems ostensibly indicated by them, a formatter board failure was verified by a call to HP tech support. "Neil" led me through a couple of attempts to "reset" the board. No luck. He then outlined my options: $270 to fix it if I ship the printer back, $340 to swap for a refurb, or take it to my local ASP for a minimum $80 bench charge plus unknown charges for parts and labor. The printer cost us $475 so these 'options' seem ridiculous. Follow-up calls by our purchasing agent (I'm in a Federal Lab) produced no movement from HP on fixing it for free (warrantee expired on mine 10-16-080). I'm blown away by this considering all the reports of this problem here and elsewhere online. From dates in this thread it is inconceivable that HP was not aware of these defective boards before I bought my printer. So, instead of recalling them they were content to keep shipping them out. Seems like actionable behavior could be easily documented on this defective product. So..I'm adding my bad experience with my P2015dn to this HP Wall of Shame for the record, in hopes that critical mass will someday move HP to do the right thing and issue a recall. At this point it seems like they think they have nothing to lose by waiting for a class-action suit, which I dearly hope will happen at some point in the future.

You would need to get the covers off to replace this. This is a pretty simple fix. You could get the instructions (service manual on CD or download for about $10). I'm not sure what the board is going for? I'm with you, HP needs to be sued bad!!! This isn't the first time they had a defective part right from factory.....Chinese parts....I told all my tech friends what would happen with quality control once HP started getting those "Chinese Parts"... - Anonymous
I provoked a few people into pushing the replacement issue with HP and other makers for a known out of warranty issue. Here is one I'll take credit for
If you push hard enough and reach the right person, they'll send you a replacement free of charge. Dr. Disgruntled, being a Federal employee and not too long out of warranty, should have a good shot at it. Once you get one printer replaced, post the details to this forum. That opens the floodgates. We had hundreds replaced in that one thread I cited. Probably in reality it numbered in the thousands since most people won't bother to post and thank us for making it possible.

One more 2015 to add to the list. The paper jam and toner lights on solid but nobody home. How do you get the side panels off?
by unknown on Dec 31, 2008 at 12:02pm Add comment
Left-side cover
1. Open the print-cartridge door.
2. At the back of the printer, use a flat-blade screwdriver to release two tabs.
3. Lift the cover away from the printer.
Right-side cover
1. Open the print-cartridge door.
2. Remove tray 2.
3. At the front of the printer, pop the front edge of the right-side cover over the two retaining tabs.

4. Lift the cover away from the printer.

It is a common problem with not just the P2015, the P3005 has formatter board issues as well.

IMO, I'd avoid any HP printer that starts with P

The CP1215 also has issues, not just with the printer but also with the toner cartridges.

Installed a P4015 not long ago and it had issues straight out of the box.

Unfortunately,it seems all of HP's recent models have issues.

Guys, HP doesn't do recalls. You can class action sue them as much as you want. They have lots of attys. The only thing you can do is get to the right person as I mentioned in a post above and get them to replace the out-of-warranty printer. If you're persuasive enough, they'll do it. Once that is done, then you post all the info here and everyone else can follow in your footsteps. Who's going to be first?

I own an out-of-warranty P2015d that had been working beautifully for 19 months. Not sure if something happened when I moved it to my new home, but since my move (late December) I've experienced the same problems described above. (Also, I've had the printer complete one job successfully after restarting it, only to have it stop working after that; sometimes it prints only one page of a multi-page job; sometimes *no* LEDs are lit even when the power is on; sometimes it shows up as "offline" on my Mac (OS X 10.5.6) even though it's still connected to my USB port and its power is on.)

Called HP Tech Support at 800-474-6836 and spoke to a technician who troubleshooted with me and concurred that this was a problem with the formatter board, and that is was a known issue. He said it affected 10-20\% of all P2015's, but that, since my printer is out of warranty, HP would charge me $260 (incl. shipping) to repair it. (I won't be doing that, of course.) For what it's worth, he said the P2035 and P2055 are "excellent printers" and that only "1-2\%" are sent back for servicing.

Hope that's helpful to someone.

My printer worked beautifully for 2 months and then I had this exact same problem. I called HP Tech Support (800-474-6836) and explained the problem and all the tests that I had done. (Thanks for all the suggestions.)

They gave me two choices.
a) Ship me a replacement and I would send back my printer in the same box.
b) I ship my printer to them, they fix it, and they ship it back.

Both of these choices involved money $45-55. I asked if there was another option and they suggested that I go to a certified service center. I got a case number, called a nearby shop, and took it in.

The woman at Universal Laser ( was very no-nonsense and knew what was the problem right away. HP gave her a bit of push back on "this type of warranty repair," but she beat them into submission and I got my printer back in 2 days. She also said that the replacement formatters are fine and the printers don't need fixing again. She thinks it was a bug in the first version of the new hardware.

All in all, not a horrible experience. It would have been nicer if the formatter didn't fail in the first place, but Universal Laser was great and the repair didn't cost me anything. I would recommend them for repairs.

Thanks to all who have posted info to this site. I was finally able to navigate the HP support maze and speak to someone who could authorize an express replacement option with free shipping. The main tasks were to first contact support via any means (e.g., online chat, 888-943-8476 and ask for laserjet hardware support..or even faster, call the all-in-one case managers at 877 917 4380 Ext 95 and ask them to transfer you..they seem to never be busy) to speak with a technician that will diagnose the problem. This is necessary to get a case number but also so that a note will be placed in your case file that the formatter is broken. The technician will undoubtably tell you that your only options are to pay to send back your printer, or pay them to mail you one. Tell them this is unacceptable. They may offer to pay for an authorized dealer to fix the problem for you..if you live close enough to one this may be a good option for you. Otherwise, tell them this is also unacceptable. Lower level support personnel will tell you to contact corporate complaints. Feel free to tell them that you will do so, so that they will not close your case number (if online, do not click the link that closes your case number, instead close the browser). Instead, what I did was contact the warranty department and convinced them to authorize free shipping.

In my case I first called 877 917 4380 Ext 95, asked to be transferred to hardware support for laserjet, then asked them to transfer me to the warranty department (the direct line may be 800-474-6836, ask for laserjet tech department, or harry prakash for instance). I was initially told that my printer was out of warranty (I know it is not however), but apparently HP sometimes begins the warranty clock when the retailer purchases from the company. Simply inform them that you purchased within one year and they will likely believe you. After Harry told me what my only options were, and I said that those were unacceptable, he put me on hold, came back and said that he was able to get authorization for free shipping. All he needed was a credit card number. Turns out that since I work for a university (and informed him that the printer was university owned) he was actually able to process the order without using my credit card number. In my case, I purchased the printer at Staples and was reimbursed by my university later.. but of course they have no way to know any of that. The only verification he required was that I provided a university email address. They will be sending my replacement to my home next day shipping (once it's off backorder).

Thank you and well done to all of you for responding to this forum. There are indeed issues with HP in getting this quandary solved. I was an instructor last year as an OSV for HP Houston. I taught the CE's in the repair and maintenance of their MFP line that were being placed at Bank of America. I am in touch with a few of the HP CE's and have sent an inquiry into this issue. I will inform you if I can get a Whitepaper on it or some sort of service note and place it in the forum.

I have 3 dead 2015's here at home that I picked up cheap. Hoping I can resolve this for very little or no money. FREE FORMATTERS FOR ALL!!

Having fixed a lot of JetDirect cards, I wonder if the same method would work on the formatters? Could be something as simple as a cold surface mount solder joint. Since you have nothing to lose, try putting the formatter on a cookie sheet, component side up. Preheat oven to 400 degrees and bake the formatter for 5 minutes. Couldn't hurt.
Update: Someone followed my advice and it worked successfully. Since then, I've baked my share of boards and had much success. Scroll down to read all the success stories.

Moe, thank you for this advice on putting the formatter board in the oven. I did it and it WORKS. The printer works. Great advice. - Thomasine
Yes, putting the board in the oven did indeed work! I used 350 degrees for eight minutes, propping the board up on 4 small aluminum foil balls to keep the board off the cookie sheet. - Anonymous
I had nothing to lose, so I baked my board on a cookie sheet at 400 degrees for 5 minutes, component side up, as suggested. The printer works fine now. Yes, the screws that hold the board are tight, but I suggest using a high quality, instrument type screw driver (I use a Wiha precision screw driver -about $5). No problem getting them out. - unknown
Thought I would chime in with my own frustration. I have a P2015dn that I got last year to replaced a very aged LaserJet 4 Plus. The 4+ wasn't dead, it just had annoying quirks and was a slow 10 ppm.

The machine ran exceptionally well up until last week when it sputtered more and more in responding to print commands. We'd power cycle it and it would come back up but eventually I got the amber lights described in the OP. Bad formatter that this and other sites confirmed. Tech support just put the icing on that cake.

I bought it right at the end of 2007 so I figured maybe someone would have compassion and get it fixed but no such luck. I got bounced back and forth between US and India tech support (the India guys are hard liners and probably have no authority to do anything beyond what their machines tell them). I found out that they considered the start of the warranty to be 1/8/08 and the day I called was 1/15/09 (53 weeks). After 30 minutes of ring-around-the-world I was to the point of swearing so I gave up. The last straw was a pleasant US lady who made it sound like she was doing me this huge favor in getting me more help for free (apparently I was transferred to their pay-for-support number) and she transferred me right back to, you guessed it, India. Wound up talking to a guy sitting right next to the first guy I had talked to in this whole ordeal. Some favor...

I made sure to give it a bad rating on Newegg (and I would suggest the rest of you do so as well to save others from this nightmare). Sadly I bought a double pack of toners at the end of 2008 and they can't be used in any other models and I sent off for a HP rebate so I can't return them. I really can't believe how bad HP is being about this. The 4+ and a 2600n are both several years old and still going strong.

Incidentally the number 877 917 4380 is for PC support (the extension is irrelevant, just dial any 2 digits) and was unhelpful in my quest to get a fix for the printer but is great if you want US tech support for your HP PC.

On simsuz's recommendation above, I got in touch with Universal Laser and looked into my repair options. Because my printer was six month's out of warranty, they weren't able to give me a better quote than the $260 HP had quoted me for replacing the formatter board. However, they were VERY helpful in talking through my options with me, spending significant time and ultimately recommending I buy a replacement printer through another retailer (they sell higher-end business printers).

The Universal Laser technician said that she had seen many of these P2015s come through the shop; she had three on her workbench as we spoke. I asked her who she thought the best laser printer manufacturer was, and she said without hesitating, "HP." So despite the problems with these P2015s, she still thought they made the best laser printers overall. She couldn't speak to the newer P series printers because they're too new, but she thought they could be good options.

As much as I hated going back to HP, ultimately I decided to purchase a P2055dn (b/w, duplexing) for along with a 3-year extended service plan, for a total of ~$410 before tax.

FWIW, I've had the P2055dn for a week and it's worked seamlessly with my Macs, connected to my Airport Express for wireless printing. No complaints (yet!).

Under warranty, HP sent out a replacement board (part number Q7805-60002) and this fixed the issue for me. (In New Zealand)!

I've replaced my formatter board and so far, so good. Something to be cautious of is that the screws inside the case are probably on SUPER tight and the screws are unbelievably soft. I stripped a head pretty well and had to drill it out. The left part of the case pops off easily and you can find repair manuals online with pictures of how to do it.

Another note of caution is that I would go buy the new model of formatter from the HP parts store (Q7805-69003) and not the old ones. There's still a lot of the older ones out there for sale. One guy on Ebay actually had in his listing that maybe 1 in 10 boards he was selling were DOA and that he would issue 100\% refunds if that were the case.

I bought the P2015 originally because of the HP brand. All the LaserJets I has used at the office were rock-solid.

It worked fine initially but I started to get the "two lights" problem 13 months after purchase. HP support wanted money to "diagnose" the problem - "out of warranty" they said.

Using this forum I found that I had lots of company and I needed a replacement formatter board - so I did it myself and all was OK other than the out of warranty payment. As time went on the printer would go into un-wakeable sleep-mode after increasingly short periods of time (a few minutes eventually dropping to 30 seconds after a print). It would have to be POR-ed whenever I needed a printout.

Finally after another 8 months, the NEW formatter board went into "two lights" mode. It would take a random number (sometimes 8) PORs to get to a mode which would print.


I now am using a new Lexmark C543 without problems, as it was only 1.5 times the cost of new extended toner for the P2015 and has excellent color, crisper black-and white and cheaper OEM toner. I was not tempted by HP's trade-in/up offer.

The P2015 is waiting for a local "e-cycle" event - may it RIP.

I have taken the pledge, brothers and sisters - "no more HP!".

I am having a similar problem, the paper jam and toner lights. I talked briefly with someone online about the problem but got no reasonable response.

How much are the formatter boards? And, where can you buy them?

Regardless, I think that HP lost my business in the future. I had a 4L for about 15 years that finally broke down. But, it seems that HP has reduced the reliability of their printers.

I have the same problem - worked fine until this am, now paper jam light is on - no paper is jammed and powering off only alternates the light to either the paper jam or paper out light. Went to HP support via the "chat" I too "spoke" with Neil who gave me the same it will be $25 just to speak with him as printer out of warranty. I was shocked - $25 just to talk with someone and based upon my description of the problem that he got to see before he chatted he knew exactly what the problem was. In the end I took some parting shots at HP support not being able to diagnose the problem and he responded it was the formatter that would have to be replaced - thus I went searching and landed on this website. It sounds to me like it would simply be cheaper to buy a new printer especially if there is no guarantee that I won't have the same issue 8 months from now. Sigh I wish HP quality was what it used to be. Now I have the quandry everyone else has - do I buy another HP just not a P or CP product hoping for the old HP reliability or do I go with Brother, or Lexmark? I think I will go for the $99 laser printer deal whichever brand it turns out to be as the cost of replacing when it breaks is about the cost of a toner for this HP.

I have about 2000 of the P2015 in our schools and I am replaceing at least 7 to 10 of them a week. I am on a first name basis with some of the phone techs. if the paper jam light is on you better have a warranty or you will be buyin a formatter board. HP no longer makes the P2015 and has steped up to the P2055DN we have 3 new schools with this printer and it is a workhorse so far. That does not mean that I have faith enough not to get the 3year next day exchange, that little extra has saved me hundreds of dollars.

I have had my 2015 at a "certified HP service center" now for a week only to find out that HP doesn't even have the boards in stock anymore. They are back ordered to mid-Septemeber at this point. The techs are allowing a "courtesy" solution of shipping a refurbished printer to me at no charge - of course, after after 4 calls and complaints. Here is the caveat - I have to provide a credit card number for them to charge the full replacement(new price, $400 not the refurbished pricing)which will be held until they receive my paperweight (since it won't do anything but hold paper now) back in approximately 7 days due to weekends and shipping times.

HP was highly recommended brand when I purchased this POS. At this point, I would stronly urge substantially reasearching before buying any other HP printers as this issue was noted as far back at 2007. Had I done as much research then as I have done now, I would not have spent money on HP. Cleary, HP is a company more concerened about their bottom line than putting out a quality product or superior customer service.

I finally received some new formatter boards from HP for a bunch of warranty repairs that have been building up over the past two or three months. Of coarse I had to call several times and go through the run around in order to get to this point but...

I originally ordered part number Q7805-69001. The parts that came in had paper work that claimed they were Q7805-69003, yet the parts themselves had a sticker that said Q7805-69004. Looks as if HP has now gone through 4 generations of this board in an attempt to solve the problem(s).

Anyway the new boards seem to work and solved the problem(s). I have no idea how long they will last but I guess we'll see.

On a side note I just receive a HP LaserJet M2727 for repair which seems to have a defective formatter as well. It gives 49 errors when sending faxes. Hp has a service note claiming it only needs a firmware upgrade, but that did not fix the problem. Part of the note says it may need a new modem board, but I'm betting it's the formatter which is at fault with this unit as well.

I'm surprised there is not a similar thread for the P2420/P2430 and P3005, which seem to have some major formatter board issues as well.

by AngryatQuality on Aug 27, 2009 at 9:43am Add comment
Use the following information at your own risk.

I found one of these LaserJets sitting outside next to the trash last spring and brought it home. I found this forum because I had the same jam light stuck on, no network response, most likely the formatter board problem.

I removed the formatter board and followed moe's suggestions above about trying the oven trick to fix a possible cold solder joint problem. I preheated the oven to 400 F and cooked the formatter board for 5 minutes, pulled it out and let it cool. Later that night I plugged the board back in to the printer and the status lights did their proper cycle and the network interface came online. I was able to connect to the web admin interface and everything appears to be working properly. There was no toner cartridge with the printer so I have not yet been able to print a test page.

For those with no other options and don't mind experimenting at their own risk you might try placing the formatter board in the oven as follows. To prep the board I removed the thin black piece of plastic covering surface mount components by the memory socket and the white sticker near the middle of the board. To keep the board elevated in the oven I used four 8-32 machine screws with nuts on either side of the board through the existing mounting holes to act as standoffs. I kept the main side of the board facing up. I then placed the board on a cookie sheet lined with aluminum foil in the oven. Be careful extracting the board from the oven as not to jar any surface mount components from their locations.

On a side note, I did not come up with this idea, just borrowed what other people had tried for other JetDirect card issues.

Hi! I seem to also have a problem with my P2015d. Where exactly do I find the formatter? Thanks, Stephan - unknown
I purchased one of these for $100 as it was a demo at a local office supply store. Printer had done 8 pages when I got it home.
I was very happy with it up until it started to flake out as many have documented here.

After thinking about the large number of failures and considering that I had nothing to loose I took a gamble.

Disclaimer: Should you choose to do the following steps you are doing so at your own risk to your property. Your results may vary, I make no guarantees that what I did will work for you. Keep in mind I did this 3 days ago, I could go home this evening and find that the printer is totally dead again. If things blow up don't call me or blame me.
You have been warned.

I was betting the problem was related to the Ball Grid Pin array soldering of the chip to the formatter board. I removed the formatter, placed it face down on three ball of tin aluminum foil on a cookie sheet and baked it at 350F for 8 minutes. Remove from oven and let cool undisturbed. I then reinstalled it in the printer and it seems to work fine.

This procedure has been tried with some success to repair video cards and XBOX 360s. Google for Ghetto Electronics Repair.

If you do choose to try this fix and it works for you please let me know. Yeah if it does not work for me please also let me know. I'd like to keep track.

I've used this method to revive a HP M1522nf to life. The printer had been locking up randomly (usually shortly after printing something)

It worked pretty well, the only catch is that the backup battery on the board popped it's guts out. So I need to solder on a new battery, but given the cost difference between a new battery and a new printer, I'm happy with that.

Cheers! - unknown
What does the formatter board look like? I would like to try this out. I have 3 printers like this that do not work at my school. They are on my list of items to delete... I don't have anything to lose... - Anonymous
You were pretty lucky this worked. 350 deg F is nowhere near hot enough to melt solder. You need about 700 deg F for older lead type solder, and for a good melt you would need 800 deg F for the newer lead free solder.

All your baking did was cause some portions of the board to expand and then contract as it cooled. This is a temporary fix. I have seen this fix all over the internet for the PS3 and Xbox, and all the people talking about it seem to thing it's the best thing since sliced bread.

I have seen four PS3s that have had this fix done, and the best one lasted three weeks. All the rest would die again after a week. We have used tools from heat guns to surface-mount desoldering stations and the fix never lasts. Since the main board you fixed doesn't actually get hot, then you may have achieved a permanent fix just though sheer luck. PS3s get very hot, and the same goes with Xboxes. You can hear then make loud ticking sounds as they warm up or cool off, once again caused by expansion and contraction. I wouldn't count on this fix to be permanent. - Mergatroid
i found this forum on a search for help with this printer...i baked at 350 for 8 cooled an replaced as i was on the phone and computer with works!!! thanks for the help!!!

- [email protected]

I had the problem with the formatter board where the paper jam and toner lights are on / no printing. I first tested that it was the formatter board that was the problem by removing the LHS of the printer with a flat screwdriver to prise it off at the back (the whole side not just the hatch) and pressing the 'print without formatter' button hidden just below the bottom right of the formatter board with a pen - this worked (page with horizontal lines came out) so formatter was the problem

I took off the formatter and put it in the oven for 8 minutes at 190 celcius (375 farenheit) after cooling I replaced it and so far the printer is now working fine. Hypothesis - one of the solder joints is faulty?

Hope this also works for some of you.

I baked my formatter board in the oven at 350 for 8 minutes and now my P2015dn is up and running again. Thanks to everyone who shared the details on how to do this.

Un ... fregin..real !!!! The oven saved the day again! As you all described, HP was virtually useless in helping. I WAS under warranty but all they could suggest was 1) mail the unit back (at my cost) or 2) Pay $69 for a refurb unit. I requested local service and they could not direct me to any local service facilities and could not give any info regarding possible repair charges. With the dead end at HP, I resorted to the oven at 375 for 6 min and poof!!! printer fixed!!! Thanks to all of you who helped keep this printer from becoming a boat anchor and no thanks to HP for your lack of help! For my next printer, I'll try ANYTHING but HP!

Yeah it's real seems like HP (and to some extent us) got burned by a supplier not properly reflowng the ball grid pin array onto the circuit board. From what I understand this is the same problem that Microsoft has with the XBox 360.

With a pile of 25 broken ones you've got some serious baking to do.

What do you have to loose?

Good luck!

Thanks to all who suggested the 'board baking' technique.

I have had two of our department's four P2015 machines show symptoms of a failed formatter board (intermittent problems then all status lights staying lit except for the paper jam light). Each time, the hardware crapped out on us just a month or two after the printers' warranties had expired.

I was VERY skeptical about putting a board in the oven, but after spending about $100 for a replacement board on the first printer, and getting the run-around from HP support with the second, I figured I didn't have anything to lose. I tried it last night as a last-ditch effort, and it WORKED!

It's a leap of faith, I know, so go at _your_own_risk_. Taking from the comments above, though, here are the exact steps that I used (with great success):

1. Preheated the oven to 350F

2. Removed the formatter from the printer (duh).

3. Removed the thin black piece of plastic by the memory socket.

4. To elevate the board in the oven, I placed it face down on three (golf ball-sized) balls of crumpled aluminum foil on a cookie sheet (that I had already lined with aluminum foil) taking care that the foil balls were not touching any of the soldered parts.

5. Baked it at 350F for 8 minutes exactly.

6. GENTLY removed the cookie sheet with board from oven and let cool undisturbed for several hours.

7. I then reinstalled the formatter board in the printer and it fired up without any problems whatsoever.

Since it had been suggested that these boards shipped with defective soldering, I'm not at all surprised that this technique worked. Regardless, I am absolutely thrilled that it did. Good luck to all.

I don't see where the risk is. If the formatter board doesn't work. You can't break it any worse. Heating it is either going to make it work, or it'll still be dead. Given the high success rate from the people who have tried it, where's the down side?

Tally one more vote for baking 8 minutes @350F.

I had done sufficient troubleshooting to be certain I had a bad formatter board in my P2015d, so I had nothing to lose. After a few minutes of heat and a couple hours of cooling, I replaced the board and it worked great. I never would have believed it enough to try it if it hadn't worked for so many people.

Thanks to moe for the idea, and to all those who confirmed and added details to the procedure!

I baked 4 HP 4Ps (3 no power, 1 light printing) & 6 HP 4Ls (4 no power, 1 light printing, 1 sensor problem) the day before yesterday.

All 7 no power 4L/4Ps power on at once after baked magically.
But 1 4P died again after about 10 minutes later, baked again and atill useless.
1 4L tested this afternoon but no power again, baked another two times uselessly..........
Tested another one 4L at the same time that is still alive.

All the other 4P/4Ls do not test again yet, maybe another day I think and hope they are all healthy then.

The two 4P/4L with light printing are still the same.
The last one with sensor problem's 4L is still the same too.

This works on later model printers as I think the quality control for the soldering of the formatter leaves a lot to be desired. I do not think it will work on older models with any consistency since those we made many years ago when different procedures were used and quality control was better. It seems that P2015 and later printer that develops this issue seem to come back to life about 95\% of the time.

by unknown on Oct 21, 2009 at 1:14pm Add comment
If you do a search for P2015dn formatter board on ebay, you'll likely see a picture of it.

On the left side of the printer, if you remove the small cover and see the memory slot, that slot is part of the formatter board.

To remove the left panel, the back end of the printer is the open seam for the left panel - with no particular notch to pry. Use a flat-head screwdriver to carefully pry that opening. It should push out that left panel for you to remove.

Once the left panel is removed, the formatter board will be visible. Remove the four screws and gently unhook the few ribbon/wire connectors... then bake.

I really do not think 250 degrees F is hot enough. I did 3 2015N boards and 17 jedirect 610 and 615 over the weekend and all but 1 tested good. I have one of the 2015N boards in a printer cooking overnight to see if the freeze has now stopped. One of the other I put in the printer this morning and it lasted to the end of the day when I put in the one that is now in the printer.

Here is what I found:

Lead solder
Tin/lead solders, also called soft solders, are commercially available with tin concentrations between 5\% and 70\% by weight. The greater the tin concentration, the greater the solder’s tensile and shear strengths. At the retail level, the two most common alloys are 60/40 Sn/Pb which melts at 370 °F or 188 °C and 63/37 Sn/Pb used principally in electrical work. The 63/37 ratio is notable in that it is a eutectic mixture, which means:

It has the lowest melting point (183 °C or 361.4 °F) of all the tin/lead alloys; and the melting point is truly a point — not a range
by dmzcompute on Oct 26, 2009 at 7:11pm Add comment

You may be right that 250F is too low. However, given that mine seems to have worked at that temp, I am suspicious that part of the issue with these boards may be some experimentation by the fabricating companies with different new solders/alloys given the push to move away from lead-based solders in the last few years. Some of these alternatives have melting points below 300F (see, for example, "Principles of Soldering" By Giles Humpston, David M. Jacobson), but how well they were tested in particular contexts is questionable.

We have a 2015 got exactly the same problem since a few days ago. Occasionally it powered up good. Before I found this forum, I did a firmware update when it was in a working state. The printer went into the “two light” mode half way through the update. Now I got a 2015 with no working firmware. Does anyone know how to force a firmware update? I wish I saw this forum earlier so I can bake the formatter as we do electronics repair here. We have all sorts of gears to do soldering. It’s a bit late now. I just wish someone knows how to force a firmware update. Any help is welcome. Thanks.
by stevenkw on Oct 27, 2009 at 5:42pm Add comment
No way. This printer came with 2 different formatters and the firmware was not interchangeable so hp pulled it off the site. What you used was a pirated version that probably fried the board. Firmware has been on the hp site in over 1 year so I do not know where you got your firmware but you are just out of luck.
by dmzcompute on Oct 27, 2009 at 6:20pm Add comment
I got the firmware from HP. It's in the hidden section of HP website. You need to google it to find it as some suggested earlier.
by stevenkw on Oct 27, 2009 at 7:14pm Add comment
That is why it is hidden, because you can fry the board if using the wrong version. Baking the board is the only way to truly fix this printer's formatter issues. Firmware upgrade or change is bogus as the problem with this board is cold solder joints and firmware can not correct a hardware problem only software. - dmzcompute
Yet another success story at 350F for 8 minutes! While I'm relatively handy, I've never really worked on computers at all, and this was a relatively easy fix to a problem that HP should never have allowed to happen. I've had the printer for 17 months and it was a real workhorse until 2 weeks ago.

It's taken me about 2 weeks to have the courage to 'bake' my formatter. I finally decided I had nothing to lose. It worked! My printer appears to be functioning normally. Why couldn't HP have been more helpful?
Thank you for the easy solution.

My principal thinks I am the bomb. I just saved us $1200 by fixing these 3 printers. Maybe she'll get me one of those laser color printers I've been wanting...
Thanks to all who suggested baking the formatting board and all the comments from everyone who said this weird fix really worked. Awesome!

Ok, first things first. I was extremely skeptical about this whole baking the circuit board thing. I figured it must be some cruel joke. However... it actually works!

To hopefully solidify anyone else's hesitance to try this, I live in Olympia WA, and work in the IT department at a medical clinic. One of our printers (our only 2015) started acting up. The thing would fall asleep and not wake up, or would show a paper jam when there was not one. There were a couple more issues as well, but they were single occurance, so no big deal.

Give this a shot if you have a 2015 that is acting up. What do you have to lose. The baking does not, and can not, to my knowledge, cause any harm to your board. Most solder melts at a much higher temerature than 350, so as long as your oven (I used a toaster oven) has a good thermostat, and you don't bake to long (or use a marranode), this is very safe. --DM--

I baked the formatter board for 8 min. in 380F to be safe (make sure the solder actually melts properly). The fix WORKED and I thank you all for sharing your knowledge.

Here's my experience:

1. To get to the formatter board take off the left plastic panel - pry it open with flat screwdriver from the back. Pictures here

2. Be gentle unplugging all ribbon cables before taking out the four philips #2 screws holding the formatter board in place.

3. The oven temp. (380F in my case) is safe for all plastics on the board, but be sure to remove the large black, and the small white sticker from it. You may put them back afterwards.

4. Preheat the oven first. Four small 1/2 inch machine screws and nuts placed in the four mounting holes will be the best to hold the board off the cookie tray. I baked mine with the heavy components side (USB connector) facing upwards.

5. After 8 min. baking remove it GENTLY. Avoid dropping the board while hot - this could cause some parts to fall off the board. Let it cool for 15 minutes before installing it back into the printer.

Thank you! I didn't think I had anything to lose and it totally worked. I love the 1 inch screw idea to hold up the board while it is on the baking pan. 8 minutes exactly! Put it back in and bam! It works perfect! You all are amazing.

Another success story for baking the formatting board on the P2015dn. From this forum I pulled and baked the board at 350F for 8 minutes, cooled and reinstalled. It did not work. Pulled the board again some days later and baked at 375F for 8 minutes, cooled in the oven with the door open, reinstalled and printer now works perfectly. I did not remove any stickers from the board and heated it by placing in a glass baking dish, component side up and did not touch it until cool. Thanks for the help.

To note, I was the previous responder (8:25 PM, two posts up) and I did remove one barcode sticker and the black plastic sheet about an inch wide and two inches tall. I held the board up using four screws stuck into the screw holes in the board. Amazing!

baked the formatter board at 180°C for 7 min (not preheated)and seems to work fine now. All lights are off after starting, exept the green led.

I used a simple dish and one screw to keep the board up. the other corner of the board was sustained by the edge of the dish an the usb-connector sustained the rest. it took about 10 min, incl cooling down.

thanks for great help to all of you.

This is awesome! I had the same problem, took it to a local service centre and I was quoted EUR 180.- for replacing the formatter board. Add another EUR 20 and you get a new similar printer..
I baked my board with the plastic joints faced down for 6 minutes at 190deg Celsius. And it works perfect :D

Let's see if it continues working..
Thanks for advice!

The printer only worked in one out of ten tries, so i looked for a screwdriver ... [email protected]°C ... half an hour of cooling ... the printer was alive again.

Just to let you know hp has issued a service note but it is very limited. They claim that the formatter issue is only recent and will only extend the warranty for 1 year for printers that were made after 1 Jan 08. In other words if your printer was made on 1 Feb 08 they will now replace the formatter until 1 Feb 10.

Hey dmzcompute,

We have 2 of these printers that failed recently just after the warranty had expired. Did you happen to have a link that I can refer to, so I can email HP for warranty and to show the authorized HP repair service centers?

Thank you,

FYI I baked mine and it's working again. I did 350F for 8 minutes on a cookie sheet, face up. With mine, I placed screws in the board so the bottom wasn't touching the cookie sheet.

Thanks to all of you who have posted on this site.

Someone gave me an HP P2015 printer because it had quit working. I had always thought that HP produced great products and I was sure I could make this printer work. Fortunately, I found this site which explained my “new� printer’s problem and how to solve it. The technique of baking at 375 degrees F for 8 minutes solved the problem, so I now have a good printer to give to someone.

I was puzzled about unplugging the connectors, so I will give a detailed description of what I did in case it is helpful to someone else.

Remove the paper tray and the toner cartridge and open the rear door. Using two wide-blade screwdrivers, pry open the left side cover at the back of the machine. When the cover pops loose at the back, slide it forward and unhook it from the tabs at the front. The formatter board is now accessible.

At the lower right corner of the board is a 28-pin ribbon connector (labeled J2) and a two-wire connector (labeled H6.) At the upper right corner of the board you will see a 13-pin ribbon connector (labeled J3) and to its left is a 6-pin wire connector (labeled H5.) At the upper left corner of the board is a 9-pin wire connector labeled H7.

I wasn’t familiar with these connectors and I couldn’t decide how to disconnect them. After asking a friend, I learned that all of them unplug by pulling off the mating parts toward the edge of the board, parallel to the surface of the board. Except for H6, the white plastic connector shells are soldered to the board and are a part of the board. In my case, at least, the white plastic part at H6 is part of the wiring harness, not part of the board, and so it has to be pulled off the board.

I’m not sure if there are static-sensitive components on the board, but I assume there are. Therefore, I tried to keep a hand or a finger in contact with the printer chassis while I was touching the board or wires. The ribbon connectors are easily unplugged by gently tugging on the ribbon, first on one edge, then the other. The wider ribbon (at J2) is harder to unplug because the friction is greater for the wide ribbon.

The wires plugging into H5 and H7 are each captured in a black plastic connector on my printer. This black plastic connector must be pulled out of the white plastic shell. I used an ice pick(!) to get a “bite� on the ends of the black plastic connector. Using the ice pick, I pulled up on first one end, then the other, of the black plastic connector. By wiggling the connector a few times in this way, the connector pulled out of the shell. Because of the extra friction, the 9-pin connector was harder to unplug than the 6-pin connector.

I found the 2-wire connector at H6 the hardest to unplug. It mates to two pins that stick up through the board, but are bent over so that they are parallel to the board. I finally pushed down on the white plastic connector with a screwdriver, trying to push it off the edge of the board, while wiggling the connector sideways. It might not have been quite so difficult to unplug if I had know exactly how the connector was made.

As other posters have done, I peeled off the big black strip and the small white strip (with a bar code and part number), then supported the board with four #6 screws with two hex nuts on each screw. This allowed me to suspend the board about 1-1/4 inch above the metal pan in which I baked it. I preheated the oven and the metal pan to 375 degrees F. I placed the board in the pan and baked it for 8 minutes, then removed the pan to allow it to cool. It was cool within 15 minutes or so, then I reattached it to the printer chassis.

The only part of the reassembly that was a little problem was reconnecting the 28-pin ribbon connector. I finally turned the printer on its side to make it easier to see what I was doing. It still took a while to get the ribbon into the slot, because of the friction. Just push on one edge, then the other and it will finally start to slide in. Keep wiggling and pushing until it is back in place.

I hope this is a help to anyone who might question his/her ability to make this simple repair.

Thanks to whoever put up the message with all the detail on how to remove the board. That helped a LOT! I decided that my printer was a loss anyway and decided to bake the board. Oh my gosh! It worked - for how long, I don't know yet, but sure am happy to have it working now. - Anonymous

Not redundant at all. This success may (I sorta doubt it)show HP the error of it's way. And the more info provided to my state's AG the better.

At least HP has produced a service note per DMZ on the problem.
Maybe they have a bigger oven.

Just had this happen to my P2015. Printer is just under 1yr out of warranty. Called HP, told them I knew it was the formatter board and that it was a mfg defect. Instantly set up a local repair option which, luckily, is w/ a company that shares my comapny's parking lot. I was pleasantly surprised by the lack of fight on their part.

Breaks again, I'm baking the crap out of the board. Thanks guys!

Hey everyone. Just to make sure, I peeled off the white strip. But which black strip do you mean? Not the black boxes on U1 or U2, right? I'm not into hardware as you can see...
And is it right, I just unplugged the cable in H6, but the white box it was in, remains?

I had exactly this problem with my P2015d and, having read this thread, contacted HP support through their web chat, expecting the worst.

After going through the usual tests that front-line support people want you to do ("please check that there is no jammed paper"...) I was told:

"this seems to a formatter failure issue. We have extended the warranty for this issue."

And so a courier pick up was organised for the next day and I will apparently have a fixed printer returned to me in a few days' time and the fix is being done for free. (This printer was 3 months out of warranty.)

Useful for others to know this too!

My office has a similar problem with our printer, but only the toner and ready lights are on--not the paper jam. We have tried 3 brand new toner cartridges from different retailers, and are now convinced that this isn't a toner issue. I have tried resetting the printer already, but no luck. Might this problem be related to the formatter board as well? I am hesitant to bake the board if this is another issue entirely. Any ideas?
by unknown on Jan 20, 2010 at 1:58pm Add comment
Are the toners hp oem or aftermarket. Your error is not usually associated with the formatter issue since yours is just saying the toner is low if the light is on solid. If the light blinks then you are out of toner. So in your case the printer should still print. Press the big button for a couple of seconds and see if the printer prints.

Thanks for your help, dmzcompute. We discovered that it was a connection issue. The hp test page printed just fine, but the test page sent from the computer didn't. We just deleted the printer and re-added it, and that seemed to work.

However, the toner light remained on, so we're thinking now that we could just be chugging through that stuff faster than we did before. We'll observe over the next few months to see how that goes. As long as the printer prints, we're happy. Thanks again!

Some pictures of the baking process

6 minutes at 180°C. I made sure to preheat the oven thoroughly as the first time the temperature light went off it actually overshot the target temperature by 30°. Wait until the temperature light has gone off, on and off again before baking.

I placed the board on top of three A4's which got a slight tan during the process. After carefully removing it from the oven I let it cool for about 15 minutes before putting it back in the printer. Needless to say that printer now works again. The thing had two recent 49.xxxx errors in the log (at about 96000 pages), time will tell if they come back. In that case the thing will go in the oven again...

I've just repaired one of these printers and will, likely, have another to repair next week.
Instead of baking the entire board I decided to attack the specific chip that has the bad solder connections. This is the BGA chip near the center of the board with the HP logo. Having repaired a few HP DV2000/6000/9000 laptops with a similiar problem (the nVidia GPU chip developes a bad solder connection due to a VERY poor design of the heat sink) I figured this repair would be similiar- and it was.

Instead of baking the entire board you can use a good heat gun (I have a Weller 6966C) to heat just that BGA chip. You want to get it hot enough to reflow the solder- so something like a hair dryer will absolutely not work. You need something that can produce upwards of 800F temps at the tip. I have heard of others using heat guns that you can buy at places like Lowes that are meant for paint removal- but that's like using a sledgehammer to drive in a finish nail.

You will want to heat the BGA chip for a few minutes- moving the heat gun around the chip (you don't want to overheat one area of the chip). DO NOT bump or move the board while you do this as some of the surrounding SMT devices may become heated enough that the solder melts- meaning they can be moved very easily. That's also another reason I'm not a fan of the Lowe's heat gun trick as those produce a lot of air which can blow the SMTs right off the board.

Then let the board cool for a few minutes. So far so good! As I said, this same trick works on the DVx000 laptops- for how long is anyone's guess though.

Here's a detailed post on use of a heat gun and a laser thermometer. As for the laser thermometer, here's where he bought it

- moe
I think that 99.999999\% of the people do not have access to a heat gun but they all have access to a oven. When you figure what it will cost for a heat gun and how much it costs in gas or electric to heat the board at 350F for 8 minutes I think it is prudent for users to use the oven method. The success rate just for this thread shows the method works, is easy, and is cost effective.
by dmzcompute on Feb 2, 2010 at 4:12pm Add comment
Another issue with using a heat gun is that it creates more local stress in the board because of temperature differences, especially when applied to a large component like the processor. Using an oven avoids most of this, is easier, cheaper, quicker, can be done in parallel and by one person. It also 'fixes' any contact problems elsewhere on the board which would take a laborious debugging process when using a heat gun. In short an oven is the way to fix these boards. A heat gun is nice to have when you want to remove components from the board for repair or replacement but it is not the tool to use for this type of repair.

In early December this printer was replaced at our facility because it was problematic. Normally it would've been thrown out, but I wanted to try to save it because it had an ethernet interface. After struggling with it for an hour or 2 I was ready to trash it but found this thread. I set it aside, and just now finished cooking and reinstalling the board. I was sure it wouldn't work because the oven got really hot and melted the black plastic thing and stunk the place up - but it worked perfectly as soon as I plugged it in. Hilarious!

People lets stop trying to confuse people here with all the different methods. Simple. Remove board and remove tape by memory slot if there. Prop up on four corners and place in a baking pan or similar so the board does not touch anything. Preheat regular oven to 350F (177C), place in oven for 8 minutes. Remove and let cool for 30 minutes and put back in printer. All these I used 10 minutes at 375 and this type of grill and left tape on, etc, etc etc confuse new people who have never done something like this. They need simple concise directions without the added variations. I know it is not intentional but many will not even try the method since all these posts with variations make it confusing.

OK...OK... I'm a believer now and I'm skeptical in nature when reading some of these threads.

When I read all of the postings about baking the 'formatter' card I just laughed and then decided what do I have to loose????? OK...if it didn't work, I would loose 10 minutes and whatever the power was to bake the card. I probably should get the boss to reimburse me for the cost savings...yeah right and that'll happen when pigs fly....

Note, I said... "If it didn't work"

BUT BAKING THE 'formatter' card DID WORK!!!!!!!

My settings were 380 degrees (pre-heated) for 10 minutes in a pyrex 9X13 glass dish.

The above...worked 2 for 2.

I would have NEVER believed it either till I tried it.

Thanks to who ever thought of baking the formatter board but it worked.
I'm 1 for 1 right now but have 4 other printer on the plant floor that could go at any time.
Yes I will bake them as well.

Thanks for the thread and all the helpful info. City University London 3-yr old lab printer P2015 was showing same trouble, last night baked the formatter board as advised, and now printer is working again. Thought printer was finished... but now it has been reclaimed. Very grateful!

When my colleague asked me to bake the formatter board on their P2015N, I thought they were taking the p.... I love to cook but I thought this request quite mad ! Well, I'm converted ....... baking this board for pre-heated Gas Mark 4 (350F on electric) for 8 minutes really does work. Baked last night, allowed to cool thoroughly, fitted this morning and now printing as good as gold - I hope it lasts.

Many thanks to the very clever people out there.

Hi guys!

I had a P2015 who had it's Paper jam light on constantly and I put it in the owen for 8min and 190C (374F). WORKED like a charm.

And I did the same with a P3005 who was acting up and randomly stuck on bootup and hanged during prints, 8min and 190C (374F).
Alive and kicking like never before.

Thanks for this amazing tip!

Yes - Baking the formatter as described really does work! I had my bosses HP 2015 printer with the dreaded error lights that would not go away (paper & toner). I tried baking the formatter board at 400 for 8 minutes, let it cool down, and then re-installed it.

Presto ... the printer cycles through without errors and works again. Hallelujah!!!

Hey HP! Here's a novel idea ... How about you send replacement formatters to all of us that you sold defective equipment FREE OF CHARGE! I am about to put my 3rd formatter in. The second one responded well to baking the first time but a subsequent attempt when it stopped working again resulted in it getting too warm and melting components. I bought the new formatter only 5-months ago.

Come on HP - own this problem and make it right!!! This is unacceptable and reason enough to shop around for something of better quality. Defective printers that aren't backed by the manufacturer is not a reputation HP wants to have.

Mr Martin I see you have posted to just about every board out there with your complaint. HP does not monitor these boards so do not hold your breath. As to your issue it would appear that you do not have a very good oven where the temp is truly regulated. 99\% of the people who use this method have success and the printers continue to work. If the temp is to low then the solder does not reflow enough to make good contact and as you discovered if to hot you melt components. If you had used a good oven and followed the instruction posted above I am sure the printer would still be working. I have done 11 of these and all 11 are still working. - dmzcompute
I read every post on this thread and have disassembled my printer with great enthusiasm and optimism. I can't wait to get home and postpone supper for baking the board. Maybe I'll order pizza! I want to thank all of you who have posted, my boss thinks I am nuts, but he is willing to let me try fixing this thing (P2015d). If all else fails, I get a new printer, which is where I started this day anyway. Wish me luck!

We both share in the blame for coming up with the fix. I originally got the baking method from DMZ as applies to JetDirect cards. I figured if it worked on JetDirect cards, then maybe it would work on formatters as well. So that part was my contribution. It doesn't seem to work on anything but the P2015 and the P3005 so far. I've tried it on other formatters, most recently a 2605N yesterday which had a bad network port. That was unsuccessful, but before I spend $200+ on a board, it doesn't hurt to try and bake it since that only costs a few cents worth of electricity. - moe
Luck was on my side. My printer works again! Thank you all so very much for allowing me access to your knowledge. The posts gave me the confidence that I could actually pull this off. And, no, I didn't order pizza.

by unknown on Feb 25, 2010 at 11:50am Add comment

You are not doing something right as I could see one of them not coming back to life but 2. No way. You place the board so the BOTTOM of the board does not touch the pan and the chips are facing up. You can use balls or screws in the holes or whatever but the card needs to be propped up so it does not touch the bottom. Now you preheat the over to 177C and when the oven is ready place the board in the oven for 8 minutes. Remove the board and let it cool in the pan for 30 minutes and then put back in the printer. By the way what issues are you having. Maybe your problem is not the board but something else wrong with the printer like a paper jam or whatever. - dmzcompute
Well you two have saved my customer alot of time and money.

HP used to use fixes like this.
I remember a paper clip fix in the HP 2631 dot matrix printer.
This one was in a service note given to hp field techs.

Are you kidding me?

That's what I asked myself as I read through this thread with a dead HP LaserJet P2015d by my side. As if on cue it died 13 months after purchase. It had the same issues discussed here with toner and jam lights.

I thought the baking suggestion was a joke on HP LaserJet owners kind of like a snipe hunt. But I was willing to give it a try. Last night after my wife made a delicious cheesy casserole, I baked the board for 8 minutes at 350 degrees and let it cool for 20. This morning I installed the board and it's working. Woo hoo!

I did not remove the black tape. It was stuck so firmly I thought I would damage something else by taking it off. I placed the board on a cookie sheet supported with 3 balls of aluminum foil, component side up. After minute 7 I began to smell electrical parts. I pulled it out after minute 8 and voila -- a working printer.

I really appreciate you all sharing this information.

Add me to the list of successful bakers. 350 degrees for 8 minutes. My P2015d is a little over three years old. It has been turned on almost the entire time. A few weeks ago I started having to turn it off and back on in order to print. It slowly got worse until it did the paper jam and toner light thing. I baked the board last Wednesday, let it cool for 45 minutes, put it back in the printer and the printer worked. I went out of town for four days and left the printer on. When I came home I did a test print and it worked without rebooting.

I think it worked....
10 minutes at 360 degrees.
I waited 15 minutes for it to cool and re-installed the board.

I had no problem sending four print commands to the printer. Previously, printing from my Mac was hit or miss. I was almost instinctively reaching for the power button each time I sent a print job to the hp 2015dn (ethernet).

I had inconsistent printing before applying the oven fix. Sometimes it worked normally, other times it was extremely slow, and often it would need to be power cycled. For a year, I thought it was a driver issue so I kept trying new drivers.

I will need to test further to make sure that the p2015 is waking from sleep properly.

Removing the card was very easy. You just need to remove the left side panel using a screwdriver to pry at two points along the back of the printer. All the cables pulled out with a solid tug. A philips screwdriver was used to unscrew the board.

I baked it in the oven propped up by aluminum foil on the two ends. I also put a piece of parchment paper on the cookie sheet that I placed the board on.

So I went ahead and baked the board at 350 for 8 minutes propped up on rolled foil cylinders and then installed it back in the printer after about an hour or two. Printer is responsive now and receives documents; HOWEVER, pages are coming out blank, cartridge has toner, and the control board doesn't say that it needs a refill. any help would be a appreciated. Does anyone know what board connection is responsible for the toner to be dispersed? I will try powering it off and reattaching all cables. Thanks in advance.
by unknown on Mar 28, 2010 at 1:24am Add comment
The first thing I would do is an engine test. With the left cover removed and looking straight at the formatter board look at the front of the board and then look at the bottom and there is an opening in the frame of the printer. Look real close and you will see a small button switch which is the engine test switch. Use the end of a qtip or whatever to press the switch with the formatter connected and paper in the paper cassette and the printer should print a single page with lines. If it does not have lines then the toner cartridge or laser/scanner shutter is the problem. If it has lines than the formatter has an issue. Generally if the laser/scanner cable is not connected right you will get a error message of 3 lights on solid. I would still check the flat ribbon cable which is at the top of the formatter towards the front which goes to the laser/scanner. If still having issue, then you may want to remove the top cover and check the action of the laser/scanner shutter to make sure it is open when the cartridge is inserted and the front door closed.

Seems the issue wasn't just the formatter board, the catch/push button locking mechanism for the toner door on the top right had fallen apart so I had to remove all panels to get to it and figure out how it all went together. There is no documentation on this part, just vague black and white images if you look for it while skimming over the support manual area on removing panels. the 2 white pieces only go together one way, slide the rectangle into the whole as best as possible, and then pop the cylinders of the other part into the designated holes AFTER you put the spring over the cylinder that would be closest to the control panel had it be installed. Trickiest part is holding the spring down so when you pop in the parts and release the spring it catches under the round "bar" and creates tension against the switch. This solved pages printing blank and the baking HALF solved the issue of the board constantly reporting a paper jam. Every time I turn on the machine it blinks stating that there is a jam and no toner but if i open the door and close it I get the green light. Before I would open and close it and maybe get a green light but usually it would then tell me its out of paper. This has been an adventure.

PS: clean your oven afterward, you don't want any of the carcinogens released from baking embedding in your oven walls and later into your cookies.

Thanks everyone for the help and support. Corporate "tech support" is beyond a scam and is only there to feed off your wallet. Remember, if the brand only lasted long enough to fulfill it's warranty then it's time to try another brand, not feed the same company to replenish the market with more planned obsolescence.

Last night I lost my IP address. I then re-assigned it and now I can't get it to print from the network. I can ping it, hit the web page for it, but can't do any type of printing or add it as a network printer on any computer.

The USB printing works fine.

I tried flashing to 20080312 (I think that's the FW) Although the flash worked, it didn't fix the networking printing issue.

Does this sould like a formatter board?
by MattM1121 on Apr 5, 2010 at 11:56am Add comment
Does not sound like the formatter issue since it appears everything is working but you can just not send a job to it. I would first try a cold reset and let the printer find a new ip address. Just hold the button down after the cold reset and 2 minutes after the printer comes to ready for a couple of seconds until both lights flash and the printer should print a config page. See if it found a new address and then load the printer onto one pc as a local tcp/ip printer and just use the driver for the hplj4100pcl built into windows. See if it now prints. If it does, then your issue is something with the network, drivers or printserver if using one.
by dmzcompute on Apr 5, 2010 at 5:32pm Add comment
Thanks DMZ,

I decided to add the printer to a computer by the IP of the printer. Once I did that I can print to the printer just fine. I added it to my print server, added the necessary drivers, and computers can get to it just fine.

My concern is that the IP address was lost when I turned it on. Now I can't add the computer by browsing the network. I used to be able to see the printer when the computer searched for it. I'm wondering what could have caused that, and why the funcationality is no longer avaialable. That's why I had thought the formatter board was heading south.

I did try adding the printer to different switches. A 1gb and 100mb switch.

Thanks again for you help.

I fixed my formatter board by baking three months ago. Unfortunately, over the last month it began displaying the problems again (needing to restart every time I tried to print) and it finally died completely. I tried baking again, but it didn't work. The test page prints and the engine page prints with lines. I tried chatting with tech support but they only offered the same options. Any other ideas? Or, more likely, can anyone recommend a really good brand of laser printer that prints duplex pages and doesn't cost a fortune?

Thanks for all of your help - I got an extra 3 months, anyway.

Allie it looks like the printer is fine and you have a communication issue. How is the printer connected. If by usb cable try plugging into another usb port on the computer or get yourself another cable. Remove all the printer software and try loading again. Unless the port has gone bad on the printer it should still work for you. - dmzcompute
The bake technique works just fine! I did it today. Remove tape over RAM socket, support corners so the card doesn't touch the aluminum foil and bake at 350 deg. for 8 minutes, . Don't know how long it works for but I will keep everyone posted.

Sure sound like something with the communication is wrong. Did you try plugging something else usb into one of the ports on the computer to make sure the computer sees it. Just trying to make sure you are not having computer issues. If the ports work then I would think the formatter needs to be replaced.

Sheesh - Just purchased a couple of these machines off the internet for cheap - now I know why. Going to use them for testing toner cartridges in my remanufacturing endeavors. Spent a whole day yesterday going thru why the printer would sometimes work and not work - a different set of lites coming on and blinking every time it was turned on. Engine test OK all the time. Just like as documented on this thread and another similar to it right on the HP official Business Support Forums website. Haven't even tried the second one yet!!

I can't believe that HP is ignoring all this trouble and attention. Where are all the purchasing agents and their lawyers; - to bring some reality to this situation. There was some class action brought against HP several years ago on the 5P/6P/1100 paper feeding problems that brought out a free fix for the problem. Of course by the time it was settled most of them were already in the dumpster. Probably same for this case - just stall and act stupid like you don't know anything about it and it will go away. I looked at one of these machines a few months ago at our local hospital - for the O.R. room - with complaints similar to these but it was on a complicated network system and couldn't be removed for further testing - everything worked fine while I was there. The network guy just said they would replace it because it would cost too much to repair it. How many of these printers are already in the dumpsters or E-cycle stations? Hundreds? Thousands? Here we pay an E-tax or fee everytime you buy a new piece of electronics. Should we have to pay that to bury a company like HP's problems after barely getting thru a 3 year warranty period that was probably badly administered anyway.

This P-2015 I have here was manufactured in May/08 and has 7000 prints on it with this problem. It supposed to print 20 some pages per minute. In my back storage room I have an old HP 3si printer that printed at 17 pages/min, was built like a gravel truck, with a couple hundred thousand prints on it. All it needs to put it back in service is a fuser unit and some paper rollers. No problems with eletronic boards or solder connections!!! These things are the heart of these machines and shouldn't go bad on this scale.

I guess I will try the oven trick. !?!?!?!?!? I've heard of it before with a network adapter board but never tried it. Meanwhile there should be some lawyers out there looking for some work! And of course we can do our voting with our feet or better yet with some negative advertising like they are doing with bum drugs some of the drug companies are flogging.

I've said too much - I didn't even have time enough to read all the posts in this blog here - got to go now!

Well the one that was made in May of 2008 is still covered for the formatter issue. HP has a service note which extends the warranty 1 year for any P2015 made after Jan 08. You need to hurry since yours will only be honored for 1 more month. If you do not want to get it done under warranty, then bake the board.

I don't believe it, but baking the formatter board fixed my HP P2015d. Let me explain exactly what happened, for the benefit of others with this problem.

The Problem:
1. My printer was displaying a solid amber "jam" light, and no other lights. There clearly was no jam, and when I ran the HP ToolboxFX software that came with the printer, it failed to connect to the printer.
2. I removed and replaced the toner cartridge. No change.
3. I followed instructions to cold reset the printer and to do an NVRAM reset. No change. (See entry in this thread "Re: Laserjet P2015 displays Paper jam and Toner lights by Avirium (8/10/07 7:23 AM)")
4. I turned the printer on while holding the Go button for more than a minute, to try and reset the formatter board. No change.
4. I removed the left cover of the printer (this is the side that has the small door in it). To do this, turn the printer around so you're looking at the back. Place a flathead screwdriver between the back of the left side cover and the back of the printer, at the top. Gently pry the cover off. Repeat at the bottom of the left side cover.
5. When the left side cover is removed, you will see the formatter board. I now performed an engine test. To do this, I turned the printer on while pressing with a pen the small button that is found inside the hole at the bottom right of the formatter board. (See

The printer successfully printed a sheet of paper with lines on it. This confirmed that the printer engine was ok, but the formatter board was dead.

The Solution:
1. I unplugged the printer and gently disconnected all connectors from the formatter board by pulling gently.
2. I unscrewed the formatter board.
3. I removed the plastic cover protecting the right side of the board, and the white sticker.
4. I covered a cookie tray with aluminum foil and placed the board on it, face up, using small screwdriver tips through each screw hole to keep the board elevated.
5. I preheated the oven to 350 degrees.
6. I baked the board for 8 minutes
7. I removed the board and let it cool for 30 minutes.
8. I replaced the board, and it worked. Unbelievable.

Good luck everyone!

Baked the board - just threw it on a cookie sheet and stuffed it in a 350 degree oven for 8 mins. Didn't even bother with aluminum foil, etc. because I just assumed it wouldn't work and I would be throwing the whole mess away in the morning.

HOWEVER - stupid printer now works brilliantly!

Hey everyone.

I am having a similar issue with a P2015 I am repairing. The forum had this link posted after one of the repliers had posted the exact issue I am experiencing.

I plug in the P2015, and all lights turn on except the paper out light, and stay on. The printer does not continue in boot up mode, or attempt to do anything else. I swapped the formatter from this one into another P2015 I am working on that was having the paper jam light stay on no matter what (formatter issue with that one), and the formatter board from this one is working perfectly fine in the other one. It boots all the way up, can print to it, as well as print out configuration pages with no issues. In the service manual, it does not state anything regarding that light sequence, so I was wondering if anyone else has encountered this issue and gotten it resolved. I am currently having the ECU board and a new fuser just to rule those out in the off chance.

I saw another formatter board (for a P3005 I think) with what looks like a small button battery soldered to it, like you'd find in a calculator. Is that what this is, and is it present on the P2015 formatter board? If so, does it have to be removed somehow before baking? I would like to try the fix, as I have a P2015 exhibiting the same issue.

I don't understand the reason for this reply. I've baked a lot of formatter and jet-direct boards. Worst case failure was 9 months. I don't see most of them fail again. As for it being a temporary fix, the boards didn't last very long in the first place before failing. That's the reason for all these posts on this thread. If I had the choice between a relatively simple procedure that was FREE, or buying an expensive new formatter that probably wouldn't last any longer than the original, that would be a tough call.
I see a lot of happy people on this thread, no complaints and one naysayer.

Would a working 2015n formatter board work in a 2015 printer? Just curious if anyone knows and if it would give the 2015 networking capabilities. It's been a while since I took the printer apart and don't remember what was need to make it networkable. Thanks.

I read this thread about 8 months ago when troubleshooting a P2015d, but was never brave enough to try it out.

Just got another one today 7/1/10 from a user with a solid amber paper jam light only. Unresponsive to any cold reset or NVRAM reset procedures.

Fired up the oven to 350F, propped the formatter board up on a few screws on top of a baking sheet component side up. I removed the black sticker/shielding on the board by where the ROM chips goes and one other small sticker before baking.

8 minutes in the oven and 40 minutes of cooling later I am proud to report that the printer works flawlessly. Many thanks sparkyjack for intially suggesting this and thanks to all of you that were brave enough to try it before me!

Now I'm going to go look for more of these in my office that I can fix.

Please to report, so far so good. Baked 8 minutes at 350F.

Plopped the printer on the kitchen table at 9:30AM. Popped the left cover off with a quick twist of a screwdriver at the top of the upper left rear corner and bottom (actually don't remember if it slipped off without popping the bottom). Piece of cake.

5 connectors disconnected, the two top ones with the black connectors inside the white board mounted receivers were the toughest, carefully grap the wire bundle and wiggled slowly but firmly upward, they will come off.

4 screws are tight, firm pressure on a good, properly sized screwdriver while twisting and they broke free.

Removed the large black tape and the small white bar code label (reinstalled afterwards).

Installed (4) #6 screws in corner holes, ran a nut up to the board so the screws act as little legs. Chips on the board were up, solder joints down.

At 9:50, set the board into a glass pie dish and set it in the preheated oven. 8 minutes later, took it out, set the dish on the counter to cool.

At noon, I reinstalled the Board, hooked the connectors back up, set the printer on my desk, plugged in the USB cable and Power Cord, turned the switch on.

Ran thru the light sequence, finished with green ready light on.

Booted the computer, printed a Word document, an email, a pdf. Let it sit a half hour, came back printed another Word document.

No hiccups. Knock on wood, problem solved.

It is now approaching 2:00PM as I type this, so the whole process took very little time and anybody that can handle a screwdriver should be capable.

My Printer would sometimes print, most times not. Would Power off than on and could usually get it to print after one or more power cycles. Then it would sit awhile, I would go to print again, no response.

In my case, most times, the Ready light would be lit, no others. Sometimes on power off/on cycle, it would not go to green, sometimes, all lights would go out. So in my experience, the problem was not indicated just by the Jam & Toner lights being lit (although once or twice in a Power cycle, those two lights did light simultaneously).

My printer is 21 months old.

Called HP this morning, yes they extended the Warranty. So I would be covered.

For $39, they would troubleshoot over the phone. If they decided it was probably the Formatter, the $39 would be credited back and then they would offer two Service options, one I could ship the unit at my expense, they would repair and ship back. Second, they would sell me a refurb unit, when I returned mine with prepaid shipping label, they would credit me back. It would take 1 or 2 days for me to get the refurb unit, but the charge to me was $69.

You can also have them do the troubleshoot on line (they sent me a link) and avoid the $39 charge, and if they concluded the formatter was to blame, same service options would be offered, you would have a case no. assigned and call them to arrange.

I asked if they would just send me a Board, they said not a user serviceable part (okay, if they think so).

BTW, the no. is 800-334-5144, at least that is what I was routed to.

I decided to try the bake idea before spending a dime. Figured I could always go back to HP if needed.

My previous printer was a HP LaserJet 4P that gave up after about 20 years. Kinda miffed that this one took a dump after 21 months.

But if no further issues, I'm a happy camper.

What would the temperature be for a hot air furnace? And should you smell burned plastic? Cause I didn't!

I tried preheating the hot air furnace to 350º F (+/- 180º C) and bake the board for 8 minutes, but it didn't do the trick yet...

I will try 392º F (+/- 200º C) today and let you know

After spending 35 minutes on the phone being transferred to call centers around the world by HP, I stumbled on this forum while looking for formatter board parts online.

I'm an electrical engineer and work day to day with PCB design and understand a lot about RoHS solder and design for manufacturing.

Long story short, I baked my formatter board for 8 min in a 350 degree oven and it is back up and running!

I just have to say that it really does not reflect well on HP that they could allow such a simple, well known issue ship on a relatively expensive laser printer. It is pathetic that the manufacturer in China cannot produce solder joints properly when just about any household oven can! Great advice from the forum and it makes total sense from a engineering prospective.

Another baking success today with a 3+ yr. old P2015dn. Thanks to the inventor(s) and to everyone reporting back. Some notes:

1) Our office printer had either the paper jam or paper jam + toner lights for three straight days. A printer tech couldn't find that light pattern in his service manual (nor generate a secondary error pattern by pressing the green button), so he suggested a new formatter.

2) Just a guess that there might be a connection, but prior to the lights, this printer had been having intermittent connection problems, where print jobs never made it to the printer and you couldn't connect to the printer's configuration area. Powering the printer off and on had previously resolved things.

3) I did the engine test (and got the page with horizontal lines); I also tried the suggestion (somewhere above) to reset the formatter by holding the green button for 60 secs. (made no difference).

4) Removing the wires and plugs from the formatter was a bit nerve-racking. For other inexperienced folks, the 2 blue & white plastic ribbons just pull out from the connectors (that is, there's no plastic plug at the ribbon's end); and the top-left wide plug with multiple wires was tough to get out: I ended up inserting a very narrow (paper-clip circumference) screwdriver betw. the bottom of the black plastic plug and white connector and gently levering up the corners. Be careful there, as pins are fitting into the plug.

5) I baked in a preheated 350F oven (double-checked with oven thermometer) for 8 mins.; I supported the formatter with alum. foil stands at the four screw holes, components upwards, and removed the wide black tape and thin white ID strip; "cooking plastic" smell happened during the last minute but was minimal; cool-down was opening the oven door half-way and pulling out the rack, so very gradual.

6) When I first tried the printer today, I got the same error lights as before, but then a few moments later the empty paper light went on, then a few different lights, then steady green. Printing worked. I don't recall the exact normal power on light sequence, but today's patterns seemed different. I don't know if that's meaningful. Hoping this fix lasts awhile!

I should have found this thread first. My printer was flaking out - most likely the formatter board. But I tried to do a firmware update before baking. The process froze and now I have 5 error lights and cannot do NVRAM reset. PC does not see the USB connection. Questions are:

1) Will baking the formatter card help if the firmware is corrupted due to failed firmware update attempt?

2) Is there anyway to install/upgrade the firmware without a working USB connection to the printer?

3) Any other suggestions?

by unknown on Aug 19, 2010 at 10:12pm Add comment
You might have some luck trying to bake your board then retry the formatter firmware download, it all depends on their firmware downloader design, judging by the 5 error lights, it doesn't look so good but if the USB device connects, hopefully you can re-flash the firmware.
by unknown on Aug 20, 2010 at 5:20am Add comment
If you downloaded a firmware update for this model then you downloaded a non authorized one. HP pulled the firmware update on this model since it fried the second version of the formatter. The only way to download is by hp providing a link to the file once they determine you have the older board that can take the update. Some people with no knowledge of this have posted the link which gets people who have the newer version of the board in trouble. This is probably your case. Yes baking would have probably worked but now you are out of luck. Best bet is to check ebay for repaired formatters or a non working printer where the formatter is good or can be repaired by baking.
by dmzcompute on Aug 20, 2010 at 7:09pm Add comment
Tried baking tonight - no luck - still the 5 lights and no USB connectivity. I'm not surprised.

The firmware was from from HP's site, but under a "hidden" URL. It matched the printer model number, but I guess there is no way to tell if it failed due to an incompatible board or the state of the board. Out of luck either way.

I did find this doc from HP - that seems to imply that a DIMM card will contain firmware. It refers to another printer model, but the DIMM part number is the same. I can risk buying the DIMM for about $40, or just go ahead an look for a formatter board - best I have seen so far is about $125

Anyone with any knowledge of the DIMM modules and firmware?

by unknown on Aug 20, 2010 at 9:37pm Add comment
I really don't have experience to speak of with HP specific stuff but I would say that it if the DIMM isn't specifically for your printer, it probably won't work. I think the purpose of the DIMM on this printer is to add extra RAM to the printer to be able to buffer larger documents locally to speed up your printing of large documents. Firmware is always stored in Flash which can hold information when the printer does not have power, RAM does not but thats ok, it has a different purpose.

The reason why the firmware crashed is because there are little solder connections under the chip that connect and disconnect as the temperature of the chip changes, you can imagine that if the connection breaks momentarily during programming that the firmware would write to flash properly and be corrupt, then next time it loads, the board is "bricked". I'm thinking the only way to possible save this board is to identify if the flash chip is external to the processor and somehow program with another programming tool. This would be very difficult

Best to just buy a new formatter I think.

For a long time, I've been keeping my eyes open for an old, high quality, B/W laser printer for home use.

3 days ago, I saw something on local Craigslist... HP 2015dn... I quick do a search, and start reading this page... Conclusion: Really Good Printer with a Serious Reliability Problem + a potential Unconventional Solution...

So I call the guy up. He recently bought it and some other stuff at a local government salvage auction, and he hooked it up to his laptop and it printed. I say, ok I'm interested, I will want to see it print.
Fine, Of Course, No problem.

I go over there, Really nice young couple, obviously honest as the day is long. He hooks it up to demo and you know..... the.. story!

We fool with it about 45 minutes... no dice.
Finally he says "I don't want to mess with it anymore; Here, you Take it if you want!
I couldn't do that; I insisted on paying him $10.

Brought it home, Baked the Board, Runs Fine!
This printer has a full ink cartridge in it. After a thorough inspection, it looks like it's hardly, IF Ever, been used! No Dust, No tracks on rollers, Nothing. The paper tray was more than half full. My bet is thats the remainder of it's first filling.

QUESTION: Where can I get a couple extra "defective" salvage Formatter Boards?? for spares?

Many Thanks!! It makes A GREAT Story!

I'm sharing my success story with baking the formatter board. I baked it on a paper plate for 8 minutes at 375 degrees. I didn't bother removing the plastic stickers -- they didn't seem to melt, anyway.

I did the bake "fix" a couple of months ago and the printer worked fine until last week. I started to get the same problem again, so I took the formatter board off again and did another "bake-off" for eight minutes and now the printer is working fine again. Why would it need another baking? Was there another solder joint this time?
by smor on Sep 17, 2010 at 10:50am Add comment
Probably just the same solder joints, 375 is pretty low to fully reflow the BGA but it definitely works, are you really using this printer a lot everyday or is it exposed to higher levels of vibration? If the ambient (room temp) temperature is very low, that could also cause a bigger swing when the chip heats up. I could see where maybe a heat sink on top of the chip may cut down on the thermal cycling a little and keep the solder joints intact.

Hello All
Right now I have 3 p2015dn with the same problem, fail to wake up from power saver mode, or paper jam and toner light.
One I sent back to be replaced, One I cooked the formatter board in the oven at 375 degrees for 8 minutes, and the last one I am waiting to see what to do to with.
So far the oven trick worked.

I have noticed that some of the p2015 and p2015dn printers that I have failed with a low page count on them.
I have 10 of them, one was purchased new, and the rest were purchased used.
It looks like if they have a page count over 6,000,or so, they seem to be ok.
Has any body else seen that some printers will fail with less than 2000 prints and some are going strong with 30,000 prints.

Did you bother to read all the post from the beginning. Of course many people have seen this since this is a common issue on this printer. The problem is cold solder joints that develop due to poor manufacturing procedures. Baking re-flows the solder and corrects the problem.
by dmzcompute on Nov 11, 2010 at 2:44pm Add comment
Yes, I read all the posts, what I was talking about, since no body has said how many prints they had before the printer failed,
was how many printer failed with a low page count and how many failed with a high page count. - true blue john
Some info about the p2015 printers
I checked the formatter processor temperature and it was only 10 degrees Celsius hotter than the other chips or the board. the temperature was taken when the printer was idle. - true blue john
Been an electronic tech/computer field engineer for 40 yrs. and I've encountered many unorthodox troubleshooting & fixing techniques. This is one of the better ones.

Company president's P2015D starting acting wack intermittently several weeks ago. Because of the arrangement in his office had a powered USB port replicator with chained USB cables between his docking station and printer. Naturally thought that was the problem until I connected the printer yesterday to another PC and got the same results. Found this thread, took the formatter board home last night and baked, put back in his printer this morning and it works for the 1st time in weeks.

I used a pie tin to hold the board while baking. Gently depressed it until just the corners of the board were held firmly.

P.S. The boss keeps his office VERY cold. Might be some truth to the earlier statement about temp. of the printer's environment.

It does not matter how may prints since the defect is when the formatter is made some made better than others so the failure can occur at any time.

I tried baking my Q7805-60002 formatter board, face up, at 350F for 8 minutes and the printer now functions. I was pretty skeptical but it's working now! Printed out the self test.

My printer now displays the following start up behavior (I have a 256mb memory card installed):

1) Power on, the machine hums for about ~6 seconds.
2) Jam and Fuser lights on solid for ~6 seconds.
3) Jam and Fuser lights off, Paper tray indicator light on ~20sec. (I assume this is the memory check)
4) Paper tray light out, Green Ready light on. Good to go!

Now to wait a few days,weeks,etc to see if this really is a permanent solution. My thanks to everyone contributing to this forum.

Unbelievable. Astonishing. I'm speechless to say the least.

This is the second time the problem is occurring with the printer at our Department. Needless to say, unlike the previous time, this time we are far off from the warranty period, and were really wondering if a repair was worth. Then we found this topic full of happy bakers and decided to give it a try.

It took 2 attempts. 8 minutes at 180 Celsius degrees for the first, unsuccessful (nothing changed at all after reassembly). 10 minutes at almost 200 Celsius degrees for the second, wonderfully successful!
The formatter board was put in a glass pan, wide enough to fit it, but narrow enough (actually "flared") to prevent the solderings from touching the bottom. Actually it was stuck by its corners, floating inside the pan. A sheet of oven paper was put on top of the pan when baking, in order to prevent unexpected explosions or release of any materials from the board from "polluting" the oven (after all, we use it for cooking!) Cooling down took about 10 minutes.

The printer recovered all its original functionality, although from time to time it freezes or becomes again unable to boot, leaving with the dreadful fixed paper jam led as your only friend. Regardless of a bit more baking being necessary, a big thank you goes to those brave guys who first experimented this odd but apparently effective way out of an otherwise very disappointing problem.

My thanks to everyone who has posted on this thread. I brought two HP P2015's home from the office this weekend because I am just too contrary to pay our IT guy $160 for a new board plus $45 to install it on each one. After several fruitless hours trying to even find someplace that would tell me that the motherboard was actually the problem, including HP, I ran across this website and string of postings.

I didn't figure that I had much to lose so tried the shake-n-bake fix by cooking the boards for 5 minutes at 400 degrees. Needless to say my wife having seen some of my other hair-brained fixes for things was skeptical! IT WORKED!!! Both are now functioning flawlessly.

It may be short lived - but I am going to have some fun on Monday at the expense of our IT guy!! About $500 bucks worth to be exact!

I am a teacher for the CPS and we have 3 of these printers in my room collecting dust as they have not been working for a few months. I came across this baking method a few days ago and was very skeptical to try it. However there was no harm in trying it on printers that were already "broken".

So i baked them yesterday at 350 for 8 minutes and ALL THREE PRINTERS WORK!!!

Had a 2015 printer at work that was out of warranty and exhibiting the typical above behaviours. Found this thread, and gave it a try. Preheated oven at 195C, then baked the formatter card at 175C for 8 mins. So far so good. The 2015 has been pinging a solid response for the last 30 minutes, where before it would only ping for 20 to 30 seconds after a restart and then time out again. Like Danjam47, I'll report back in a few months on how this printer is doing.

After my wife finished baking some chicken wings for dinner, she was surprised when I placed my HP 2015dn's motherboard in the oven for 8 minutes at 350F. She thought I was nuts! and..... Anyway my printer is back to life and I am nominating the person who initiated this solution on this thread for this year's (2011) CNN hero of the year for solving this problem so 'simply' after a multi-billion dollar HP Corporation and its Engineers were unable to figure it out!! Shame on them!

Wow! Go figure... and another fixed printer to add to the list. Next time a customer calls me with a printing problem I will have to tell them to try it at 375 degrees for eight minutes because that is what did it for me.

Thank you all for posting this miracle solution. Who'd a thunk?

Half-baked idea! So, hundreds of people, including lots of techs are wrong? Sounds like this guy might have contributed to the article.
Update: I called Parts Now to express my indignation at the article and basically got nowhere. I don't think testing the procedure on 3 boards is a valid sampling. If you read the threads, there is a less than 10\% failure rate, not the 66\% they claimed. I guess their sales of formatter boards were tanking. I'm sure HP isn't happy about this procedure either.

Thankful for this forum. Took time last night to try this solution and our printer now works like new. I'm glad that we didn't have to buy a new one!

I have had the 2015dn for about four or five years. Once before it failed, and as the printer was under warranty, I shipped it back to HP and it returned in a week or so. Failed badly last week, after intermittent failures. I figured, why not try this crazy repair out, what was there to lose? I'm reasonably good with technical stuff (I'm a physics teacher); the hardest thing was getting the left side cover off. Anyway, I followed the instructions to the letter (but I used two wine corks lengthwise as supports, fearful about excess heat from the aluminum foil.) Preheated oven, 350 F for 7.5 minutes, removed, left to cool for about 45 minutes (till neither the cookie sheet nor the formatter board was warm to the touch.) Reinstalled, and so far it works fine. My thanks to the previous posters.

Maybe we should all write polite letters to HP about this. Clearly, this is a manufacturing issue which can be solved easily by better soldering techniques. The problem (and its solution) have been known for about two years now. Why hasn't this been addressed already? I would think that HP really wouldn't want the public embarrassment of this oddball repair being known widely. Maybe they no longer care about their image, or maybe they think they're better off ignoring the problem. We should publicize this. Only random geeks find out about this repair; most people will simply replace the printer.

I'm gonna write WIRED about this.

My sucess with this repair is on the P2015 printers.
According to the article by parts now they only tested the P3005.

I have tried to spread this repair to other forum and was blasted for such a silly idea.
Thinking out side the box is not welcome in some places.

Oh well we know it works.

I have found that when the customer is down they do not care how only when the printer is fixed.
And when they find out this saved them the cost of a new printer I became the best tech they know for printers.

Thankyou again for this fix

Laserjet P2015 update: The unit I baked/repaired just under a month ago (Mholland, 1/4/2011) has been running fine until today. This morning the user notified me the printer was acting up again. When I checked the IP, it was no longer responding to pings. A simple power-cycle of the printer fixed the problem, but it will be interesting to see how long the printer runs this time before losing connectivity again.

@ Mholland (1/31/11 2:48 AM): Mine has always done that. Every few weeks, since it was new, pre & post baking, I've have to power cycle it because it stopped responding on the network port. - danjam47

If we used the wrong Firmware update and now all the lights except for the paper tray indicator are on and solid, will baking the board help? Can we force another Firmware after baking the board? Are we screwed here?

Ditto - moe
UPDATE: The printer has lost network connectivity again, less than a week later this time. I imagine if this printer was used as a USB printer, it might work fine. But it looks like some element on the formatter board is crapping out the network connection with increasing regularity. Since this user requires a network printer, and I don't want to repeat the whole disassemble/take home/bake/return/reassemble process every month, this printer will have to be retired for a better model, most likely NOT an HP.

Another happy baker here. Thank heavens I found this site. Worked 1st time. Biggest problem was getting the formatter board out. Easier than I was trying to do.

Preheated oven to 350F, baked 8 minutes, cooled 30 minutes. Sat on 3 small balls of aluminum foil, left to cool on baking sheet.

After spending 560.00 on the sucker, and then another $126 to HP as a deal for my 1st one for a refurb because I was just out of warranty I was SO MAD I was ready to put gasoline on it. Have worked in IT for 25 years and spent hundreds of thousands on HP printers and was aghast, simply aghast. Call HP 3-4 times but after initial BS they wanted $. I hung up.

Thought it was Vista for a very long time hence going out of warranty originally. My stupid.

Thanks you all so very much

Anyone who reads the last post be careful. Toaster ovens do not regulate temperature very well so 350F could end up being 450F which will fry some items. Better off using a good oven.

Well, my first bake lasted almost 6 months (10/30/2010 to 4/10/2011), but the \%*^$#@! printer died again today. I tried the same bake as before, but no joy in Mudville today. Tomorrow I'll try baking it a little longer, maybe 12 min instead of 8. Not holding out much hope, though.

This is insane, but baking the mother board for 4.5 minutes at 400 deg actually worked. It came out of the oven smelling a bit and too hot to touch, but after it cooled I put it back in the machine and cranked it up. It's working fine now. I think I may do the same thing with my laptop and cell phone.

It will stink, but not as much as a non-function printer stinks. And moe is right, it goes away fast. I've probably baked hundreds of RIPs now and although not 100\% success, it is pretty close. A few have failed again a while after baking. About the same success rate with the JetDirect cards as well. I do it in a toaster oven at work now since I bled some caps in my oven at home (that really stinks - but it was an overcooked P3005n RIP - the P2015dns are much sturdier and - in my opinion - can be overcooked a little).

moe, dmzcompute, Sharpie, Stephen et all: You guys are much appreciated. A hearty thanks for all your *FREE* knowledge shared...from a longtime "lurker" who has learned much from a fantastic forum.

Follow-up to my 8/19/10 post: After the formatter board baking success, the P2015dn printer kept working until about one week ago. Then I rarely got a green ready light; couldn't print; browser couldn't connect to the printer's configuration pages; green button never printed a test page, but the "engine test" did print a page with narrow-spaced horizontal lines.

We ordered a new formatter board from HP Parts and it has solved the problems.

The broken original board had a sticker with part #Q7805-60002 (again, ours is a networked model), but the replacement part is #Q7805-69003. If you search HP Parts, you'll get two choices, one of which is an Exchange/Defective Core Charge, which means returning the bad part and getting a credit, which should drop the cost to just under $100. Shipping the new part to me was free, but I just learned that return shipping is on my dime. Too soon to have gotten the core charge credit, but happy to have the printer working for us.

I would have baked the board one more time. Paying 100.00 to repair a printer that is worth today maybe 75.00 does not make sense.

OK, someone please answer this:

Solder melts at around 700 deg F.

What is heating the formatter board to 400 deg. F going to accomplish?

My guess as to why it works temporarily:

Heating the board causes small warpages that put pressure on the non-soldered balls on the BGA.

What I did to solve the problem (and it has worked on other BGA related solder issues) is to apply heat with an Ungar heat gun that puts out about 750 deg. F hot air. These guns have an outlet that is about 1/2" in diameter.

Be aware that if you overheat the area around the BGA chip, you will likely destroy the board.

I must say, you guys are GODS. Baking has worked for me, so far. (today) Thanks for the specific removal & baking instructions. For some of us, geek is only skin deep. We need direction.

NOW: Question: I have the board back in the printer. The self-test page works. The engine test page works. Opening the IP web page and printing something works (so it must come from my PC to the printer via our network, right?). But I haven't been able to print a test page nor any document from a networked PC. I have deleted and reinstalled the printer. The network seems happy with the printer. But all jobs go to "failed to print". I have re-read the entire thread. I have tried all the various "hold-the-green button for specified time" starts. The printer is perfectly happy, just doesn't want to take direction from my PC.

OH WAIT, I figured it out! I don't exactly know what I'm doing but I printed something at some point with the IP address, checked in my Printers/properties and changed the IP address. Look at me!

Moe, etc, you should really be charging for this. I am at a local government, I notice a lot of the users replying are at schools, hospitals, etc. You have saved tax paying citizens megabucks in replacements.

I did put the formatter board of 2015n into microwave oven, face up lifted with 1 inch screws and set oven to mark 5 and time for 5 minutes..
as the microwave oven started there was some burnt and small flame. i took out and checked, however there was no burnt marks on pcb, i think that should be some plastic near network port. i had removed black plastic at memory slot and white sticker at middle.

where did i went wrong, do microwave oven has different procedure. In that oven there was a round regulator to set mark to 4-5 and time was set to 8mins.

please guide.

You can not put anything with metal on it in a microwave oven. What you heard was sparking from the microwave oven. You need to bake in a conventional oven. Microwave can not be used for this project.

You can try the baking, it may work and it may not. If not best price I've gotten for a quality board is Liberty Parts Team for $99 new for the network version and $75 rebuilt for the non network version. They are sold as exchange (old board goes back to LPT)and you can buy a prepaid PRP return label from them at the same time to return the dead board.

The reason these are failing is why all the new Chinese garbage is failing - low grade lead free solder that cracks under changes in temp or motion. Micro cracks usually in the BGA mount main chip. BGA is nothing more than using spots, or balls, of solder in place of pins. The PCB and the chip carrier have solder pads and a ball of solder is between that melts to provide a mechanical and electrical connection. Really stupid system. Used on chipsets and video chips in laptops too and they fail there as well.

Anymore I replace the formatter since I've had only about a 30\% success rate with oven heating and hot air rework stations, even using alcohol based no cleanup liquid flux. Easier and if it fails right away the vendor can send a replacement formatter.

Easiest cure to bad HP printers - buy Xerox, Lexmark, Epson, Canon, etc though each of these has had problems too especially Brother and Samsung with bad capacitors lately. Just tell HP to take a hike by not purchasing their crap anymore.

I thought the "baking the formatter card" idea was a joke at first - but it seemed to be a lot of people in on it - but the printer didn't work anyway so what the hey - 8-9 minutes at about 365-375 degrees and the printer is back in business. Gotta love it!

Actually the concept is valid. I just didn't think such a low temperature would pull it off...

- Jonlberg
Well, just want to throw in what may be this thread's very first actual "failure"... sad, too, because I've done some VERY far-fetched electronics repairs, most of which are successful. This one... not so much. :(

I made a rack out of a wire hanger and evenly propped up my formatter in a rinky-dink toaster oven. As others have mentioned, an oven at 350 isn't hot enough to melt solder, so I really don't understand how it would've worked... but somehow, it did melt the solder. I discovered this through the same method that spelled my board's demise: I touched the DDR2 memory chip to "seat" it over the melted solder balls (in case that was the problem).

Little did I know that the memory chip is supported in what may be the tech world's absolute biggest flub-up of mechanical design: there's a protruding "bar" down the center of the chip that the chip can rock back-and-forth on when the solder is melted. Soo... up goes one end, down goes the other. One side got squished flat and the other lifted up. Well, nothing serious at the moment, I thought...

Wasn't until about 1 year after failing the repair that I broke down and tried to get to the bottom of the failed repair... looked up the memory chip data sheet (Micron MT47H128M8 or a variant with the same pin layout), and found that part of the "balls" under the chip on one side are a bit "off"... almost seem to be missing or just out of place. Then I think about it: yep, if that happened as I think it happened, squishing the solder down just blobbed all the balls on that side together and formed a mess.

The result? All I've been able to get out of the printer is the "Jam" light at power-on, then about 30 seconds later, it switches to "Toner" and stays there. Print engine test still works great, though. Really makes me wish I could get it working again...

Any tips? Replacement formatters on eBay are economically prohibitive... somehow the sellers don't realize it would be cheaper to buy a new printer than to waste $80-90 on a replacement formatter for a flawed printer. I *do not understand* where those guys get off charging those kinds of prices, but there's no way I'm paying it for a new formatter. Any other options, or just trash can it? :/

You made one very big mistake. Toaster ovens are notorious for not regulating temperature. Most run about 40-75 degrees hotter then the setting and if you have it set to toast rather then bake it destroys the boards making components fall off. Because of your mistake your only option is to trash it.

OK, well, I know I made a mistake there, but I think your blame is fatally misplaced: are you SERIOUSLY telling me that my mistake wasn't in, say, absentmindedly poking molten SMT-mounted chips with a stick... but... rather... that my mistake was in actually getting the board hot enough to be repaired (to melt the solder) to begin with? o_O

Don't feel bad, someone else actually microwaved their board. This comes under the category of "What were you thinking?" You bake an expensive board in a rinky-dink toaster over! I bake all of mine in a convection oven, where the heat is evenly distributed at a precise temperature. Wouldn't trust a customer's board in anything less.
- moe
Well, admittedly it DID perform its function just fine! And many others seem to have used toasters as well... really I don't blame the toaster oven for the failure (I was actually monitoring it, I'm no electronics-repair newbie), but that dang memory chip and its deceptive "center bar" that made the balls go all blob-ey when I tapped on it.

I spent a good 3 hours last night working on the thing, using a heat gun (as I've repaired some 10-15 failed nVidia GPUs/northbridges with) to re-reflow the chip from the underside and trying to straighten it out. It wasn't until the ~2.5 hour mark that I realized the balls were blobbed together though. On one hand I wonder if I have a chance at removing and "re-balling" the memory chip with some BGA balls from eBay and a stencil...

Still, I'd love to know where those eBay sellers charging $100 for a formatter for a $75 printer have the nerve to do so... :/
by Falcon4 on Jul 5, 2011 at 9:57am Add comment
Because they can. Also if you had a heat gun you could have just aimed at the main processor chip as that is the culprit to reflow the solder and all would have been fine.
by dmzcompute on Jul 5, 2011 at 6:10pm Add comment
Everyone said to use the oven, and at the time of the original repair, I hadn't gotten too confident with the heat gun yet. Now I'd say I'm about 75\% "good" with this heat gun, and I'm taking the plunge into BGA reballing right now as I type (just sending the payment for the balls and stencils now)... so... I'll definitely post back in a few weeks when I get the parts, and if it works!

I did remove the RAM chip, cleaned the pins with braid (two non-connected pins came off with the chip though - no traces were connected to them), and the printer does the *exact* same thing it did from the start: "jam", then about 20 seconds later, "toner". So I'm definitely on the right track... just hoping I don't mess up this re-balling trick! ;) - Falcon4
Second time done this on the same printer. Winter has come around and the unit gets cold at night. Shows up as offline and a power recycle fixes it. Baking does a longer term job. Could well be room temp that brings this on

with the problems indicated above, if the printer or network card is not working suddenly, COOK IT!!
If you just shy of ordering a new formatter or network, take a breath, and cook the boards. Wont hurt, and you could save a lot of cash.
it could be the new 'environmental' solder, thats comes from China or other asian countries, that is the cause.
Mind you, its environmentally friendly for the 'earth' but deadly to humans, go figure the CEO's logic on that one.

Baking the formatter board on the HP Laser Jet P2015dn Printer:
This morning at 0900 I preheated the toaster/convection oven on "bake", bottom coil only with shielding pan on lower rack and another rack in the vertical center, to 350 degrees, as measured by an oven thermometer put in the back of the center rack. I removed the black plastic shield in the board's memory module slot. I broke four round toothpicks in half and inserted both pointed ends into the four screw holes that anchor the board to printer chasis to act as legs. I placed the board, chip side up, in the center of a 7 1/2" x 12" Teflon coated baking pan, and placed that in the center of the oven for 8 minutes. I had to keep the oven temperature dial on 400 degrees to maintain the 350 degree internal temperature.
I removed the pan with the board and it cooled to room temperature within 10 minutes; the board was cool when the pan was cool. I put the back into the printer. I then did a NVRAM reset by holding down the green Go button for 20 seconds while turning on the printer. The roller and toner lights flashed and then paper light came on and stayed on for a long time. I did another reset and the paper light again came on a long time, but then finally the printer went through the flash sequence and stopped on a steady ready light.
I then sat down at 0928 and typed this document and I am going to print it double sided. Wallah! It worked perfectly. And I had put back in the memory board that I thought was the problem. It is now 0940

I just finished: removed the formatter board as per instructions, lifted off the black plastic strip from the one end of the board (so it didn't melt in the oven), put the board on a cookie sheet with (2) 1/2" tall wine cork stumps under it for support and separation from the metal pan, and placed it in my 375-degree oven for 10-minutes. After removing it from the oven I let it cool for 15 minutes before touching it, put the black plastic tape back on, reinstalled the board and now the printer is now WORKING just like new!!! This could not be any easier. Thanks to one and all on this thread!

I have 4 P2015's at work. Two were bad and two were good. I baked one and it worked! I am amazed! Waited a couple days and then baked the second one. Now my paperweights are working again!

Thanks so much for the info.

I had posted a message on 9/13/11 about baking my formatter board. Well it quit working again yesterday. It works when the board is cool, but if you leave it on it quits; after printing 10 pages the main chip reaches 105F. I baked the board again today, but this time I kept the oven at 400 degrees and kept track of the board's temperature with an infrared thermometer. It took 10 minutes for the board to reach 365 degrees F in my little oven. I quit there and it works fine now. It appears that the first time I probably did not get the board up to 350F. From my surfing I found that 60/40 solder melts at between 361 and 374F and 63/37 melts at exactly 361F (lead free solders are said to melt at 482F, so obviously the boards are not soldered with them, or melting the solder is not what is fixing the boards). If it quits again, I am going to first bake it up to 375F, and if that does not hold, to 400F and then 420F, as 50/50 melts between 365 and 419F.

This forum is fantastic! My P2015 has been malfunctioning the past several weeks-power reboot seemed to heal it. But tonight it totally died. After reading some reviews about new printers I decided to check out the review of this beast-which I bought in July 2008. It mentioned the potential problems with the formatter board so I did another search and wound up here. With the help of the service manual I managed to remove the board--baked it at 375F for 8 minutes and replaced it. The printer now works!!!

My wife was just laughing at me when I told her I was going to bake a board at 375 for 8 minutes. She thought I was joking!

Thanks a lot to the person who started this site and thanks to all of you folks who shared your knowledge. With your help I fixed my own printer in about 2 hours. Wow!!!

Well, it worked for me too so thanks. I once managed to recover data from some Western Digital drives with overheating controller chips by putting them in the freezer (In Ziplock bags of course) and after reconnecting them (Still in the bags) running them with a pack of frozen peas on the board side. Strange uses for Kitchen appliances.

I have researched this all week and kept coming up with the same solution - bake the formater board. I was extremly hesitant to do it, but given that it wasn't working anyway - why not. So I set the office toaster over to 350* ... let it warm up ... put the board on the tray (with pennies to keep it up & off the tray) ... set the timer for 8 minutes. Took it our of the oven ... let it cool while I had my lunch. Put the machine back together - performed a test print ... then a word print ... and then I began my happy dance (not sure the others in the office could really relate, but oh well). Great way to end the work week.

Man, this is awesome, thanks guys for this thread! I just saved my 2015dn by baking the formatter board in oven (8 min / (180 C / 356F). Removed the black tape from memory slot & barcode sticker. All plastics survived baking, no problem with reconnecting all the wires. Cooled down for 20-30 minutes. Thanks once again.

Another baking success story. I work in electronics, but never would have thought of that. Eight minutes at 375F. The panel to pop off is the left panel as you look at the front of the printer. I baked it with the black tape on, no problem. It shrunk as wrap on the components below. Thank you.

Check the cables and make sure that you connected all the wire connections back on the formatter as one of them is a set of wires that goes to the lights. You probably just missed that connector so just recheck.
Sometimes one of the connectors to be connected will be there behind the board so user cant see those. Look on the board itself to see if there is a connector at the top or left side when looking at the board for connectors that does not have a connection. If they are all there, then it is possible when you removed the connections you pulled to hard and the connection at the other end where the cable plugs into the small circut board for the lights has come out. Refer user manual and see how to remove the top cover which is where the other end of the cable goes. As to points no important but all you have to do is click on the drop down that says unassigned by the post that helps and after assigning click on the button at the lower left of the thread to assign the points.

Just had service man come to the office to work on two 2015d's. Told him what I had found here and once he verified the formatter board was the problem, he just took them off and left them for me to try baking. Said his company could fix the two for $450. I said I would get back to him. Thought what the heck if baking doesn't fix it, we won't repair them; just replace them. Baked my first one and voila! it works perfectly. The other is baking now. Thanks to all!!!

Just wanted to add my thanks to everyone who has posted here - I tried the baking trick last night and it worked fine, 180 °C in a fan assisted oven for 8 minutes worked great. I didn't remove the black tape and while it shrunk very slightly there don't seem to have been any ill effects. Printer is now working and even printing large (filesize) files, which it hasn't done in years.

Particular thanks to snewo (1/10/10 9:31 PM) for giving such detailed instructions on the board removal, I couldn't have done it without them!

I've been a systems engineer for over 15 years and nothing surprises me anymore. To keep the prices down (so we'll buy the product) they cut costs. The bottom-line is we end up paying for it some way. My 4M was 12 years old before it died. RIP old friend! This 2015 was Mfg'd 9/06 in China. So, it's at the half life of the 4M at half the original price. I tried the "Hold the green button down for 1 minute trick" first and that didn't work. Now we will BAKE ! With a nice bottle of chianti to go with it. This rates up there with freezing hard drives with seized bearings..... Maybe I'll get another 5 years out of it. I wish the OKI's were more affordable for end users!

Found this thread, baked for 10minutes @ 350F. Back in business for now. Yes, I lament the "old" HP, including 5si and 4, and example of old fashioned American manufacturing quality. Made a decision years ago that my business will NEVER lower quality for market share.

My P2015dn had different symptoms. It would always print after a power reset, but usually stopped printing after one document. Nothing would make it print again other than a power reset. The lights always worked normally.

Baked the formatter board for 8 minutes at 350 deg F and all seems to be well. Another one fixed.

It happens that the HP M1522nf multi-function printer has this same formatter board problem. I baked as directed and got my printer working again, however it went bad again in six months. Has anyone had consistent long term results?

I usually get a year out of them. You can't expect the baking to last forever. It is free and not that difficult a procedure. - moe
Are you suggesting that a second and, maybe, third baking might work as well as the first. I assumed that I had only one shot at this. If I can keep the printer going for a baking per year, I would try it again.

The board only lasted you for a year to begin with. The new solder mandated by our wonderful EPA has all kinds of problems. You can bake it as many times as you want. It's not like you can make it any worse. - moe

This is getting more interesting. You say the EPA mandated this new solder? Are you suggesting that if I get a new board for $108 to $285 plus shipping, it might use the same solder and the same short life-span?

My M1522nf is printing again after it's second baking. Any suggestions on whether the printer will last longer if not plugged in while not in use. Or, does the solder fail whether plugged in or not.
Thanks, dtschak

LATER NOTE: Actually,I got only one printing out of this baking before it went dead again.

If your board only works a few times after baking, you may not have gotten the board hot enough. Here is my post of 09/22/11:

I have not had a problem since then and I print with it every day. You need either a hotter oven or to leave the board in longer. Using an infrared thermometer to pinpoint the temperature of the board is best.

Hiya folks, I had a similar issue with a m2727. The thing would crash during initialization or when idle for 5-10mins.

When I found this page I was a bit skeptic but had nothing to lose, since the device is out of warranty.

So I baked the thing, 10mins on 175C and let it cool for 15min. the printer is online now for 45 mins, no problems no crashes, my face:

well, I baked mine at 400 for 5 minutes and it did not fix it.

I must say, I am very disappointed in HP.

I have used their products at home and in my business for many years. Ever since my first HP LaserJet 2 I have been a HP only user.

Their products was the best bar none.

Since they have decided the way to compete is to have cheap Chinese parts instead of quality at higher prices and protect their good name they have really gone down hill.

At least I can count on sites like this and the great people that figure this stuff out and post to share with everyone.

Thank you all that help others keep their sanity! :)

Two weeks ago I baked my HP M1522nf at 380 in a gas oven for nine minutes. It is working fine. This is my third baking. The first bake was at 360 for 8 minutes and lasted six months. The second bake was again at 360 for 8 minutes, but it didn't fix the problem totally. This time, I upped the temp and time. I am crossing my fingers. This time, I did not replace the plastic cover over the Formatter card - just in case.

The baking fix was never meant as a permanent repair. You have to realize that the non-lead solder is the problem and it will continue to be so. I've gotten as long as a year on my numerous baking projects. Best part of it is that you can repeat it and it doesn't cost anything. I have been fortunate in not gaining any weight from the chocolate chip cookies I bake before I put the boards in. Save energy, save the environment.

I used a claw hammer to pry the panel off a used p2015dn I bought today, the hammer worked great (it's the hammer carpenters use).

How about using a halogen lamp for doing the baking? I have a 500watt yellow lamp that I know gets extremely hot, I just need to obtain a temperature measuring device to know the proper distance for about 380 deg F.

This way I can bake outdoors. I'll post my results once I get a temp device, wish me luck!

I couldn't unscrew the "MH3" & "MH4" screws, too tough!

So I tried this first: I applied light pressure with my thumb on the large chip in the middle (I can see the ball contacts on the perimeter, on mine the upper right corner seems like an inadequate contact so I pressed there while turning on) - I was just now able to print a config page at least, before today this printer was DOA !!

Originally I was planning to apply heat to the chip using a halogen lamp without removing the board from the printer (by laying the printer sideways so the board is topside). and I was gonna mask the rest of the board and printer with aluminum foil. But lemme see how far I get just by applying pressure on the chip.

Reading your posts, one gets the idea that you probably shouldn't be fixing your own printer. I'll try and give you a helpful hint, but doubt it's going anywhere since you seem to want to ignore all the helpful suggestions on the thread. First you turn the printer on its side so the board is vertical. Then you take your screwdriver and insert it into the "stuck" screws. You then bear down on the screws with your body weight and turn the screw. This will keep the bit from slipping and stripping the screw if it already hasn't done so.

Bought this 2015D locally used ($40) for a friend. Only 5K Pages.

After printing with it for a while I set it aside and waited for a USB print server (Ebay $9) to arrive. Several months in between both purchases as the friend changed residence and newly required the Network.

Connected the print server and the 2015 died with toner and jam lights. Came ready after removing power and restarting, but after sending it a job it froze.

So much for me having immunity from formatter issues. :-]

Baking formatter worked fine.

If there is a repeat I will preheat oven AND cookie pan to 400F and bake at 400 for 2 min and 375 for 6 more to ensure more thorough melting of the alloy if that is the cause this baking addresses (likely).

Done plenty of jet directs. My first formatter.

There were no plastic parts to remove. Before baking I did remove some sort of residue on the bottom of the board.

Today my P2015 stopped being recognized by my computer again and would not print. It has been a year since I baked the formatter board. Here is my post of 09/22/11:

So, I put my oven on 400F, preheated it, put the formatter board in propped up on toothpicks on a cookie sheet and kept track of its temperature with an infrared thermometer. At 10 minutes, it reached 375F on the green printed circuit board, but 365F for the white plastic pieces, and 385F for the big black chip in the center. I put it back in the printer and turned it on; after a few minutes it went to the green go light, showed up ready on my computer, and then printed like a champ. See you next year.

I had one in the shop today with just the Paper Jam light on. HP's site suggests a NVRAM reset. That failed, so I figured nothing to lose by baking. Of course, it fixed it. I've never had to buy a formatter board for a P2015 yet.

I have the same problem with my HP P2015, and I'd like to try baking the formatter board.

I´ll thanks a lot if anyone let me know.

Yes, the temperature has to be maintained at 350-375 for 8 minutes. - moe
11-12 minutes at 220°C and, voilà, the formatter board is back to life. Temperature and baking time are a bit higher because there was an additional tray in the oven and I only had the board with me (and no printer to test it on), therefore I had to be sure to succeed.

I think this is the fourth time for us in a few years (the first attempt is also posted in this forum): we are becoming baking experts ;-)

I was skeptical about this thread, but after skimming through the long list of satisfied customers, I decided to give baking a try. We have an oven in our break room and the CFO walked in and thought I was completely insane, as did my boss. However, I was the last one laughing when I showed them each a printout and touted that I saved the company a couple hundred bucks on buying a new printer. THANK YOU for this original post so many years ago.

Note: I did 350 degrees F for 10 minutes, but our CFO turned off the oven prematurely, so it was maybe only in there like 6 or 7 minutes. Also, I didn't even bother removing the white paper in the middle or the big black piece of sticky paper, although in retrospect I probably should have because the black part started to shrink-wrap to the board. I did pull off the black part before I re-installed it.

It has a static IP and was frequently used across the network but now it drops offline everytime someone trys to printer to it. The network lights at the RJ45 port are still flashing to show network traffic, but when you ping it you get "destination host unreachable". The lights on the top printer only show the power light is on, nothing else.

Would this Shake-N-Bake fix work for this problem we are having?

Probably. Cost nothing to try.

Thank you, it worked. 180°C - 8 minutes.

Today I baked my printer's formatter board for the third year. See my posts for 9/22/11 and 9/11/12. I put the board back in, plugged the printer in and turned it on, and, after flashing through the lights and settling on green, it immediately printed the last document that it would not print. As I said in my last post, see you next year. (P.S.: I will not be getting another printer as I have gone fully digital in the interim, as well as the agencies I deal with, and printing on paper is done rarely now. I do not even print enough to keep the heads clean on my color inkjet. I started on a manual typewriter, using carbon paper and onion skin fifty years ago. I am still waiting for my flying car, however.)

Baked my formatter board a couple of days ago and installed it yesterday. Printer working like new. Thanks to all that posted this solution.

Same problem, happened during my busiest time of year when I need my printer to work. So I just now fixed it. Baked it at 350 for 8 minutes. Reinstalled the board and working again. I did try the reset suggestions first.

Thanks for the help.

Add one more statisfied customer to the baking solution.

We had a P2015 in the recycle pile at work with the constant Paper Jam light. After reading this thread, decided to bake it at 350F for 8 minutes. Printer is currently working again.

Thanks all who went before...

Many thanks to all the all the bakers out there.

I have two P2015's. I don't have locked Paper Jam and Toner lights. Just crashes. Mac printer queue says the communication to the printer was lost. Power cycling fixes it, but one printer is so bad that we were only getting one print out of it before we needed to power cycle again.

I baked the board at 350 for 9-10 minutes this morning and it's hasn't crash yet. It's a Summer day at a school, so it didn't really get a workout, but I'm crossing my fingers. I'll bake a second P2015 board before fall classes start. has a new formatter (w/o network) fro $159, a refirb (w/network) fro $149 and a refirb (w/network) for $139 with an exchange. I say keep bakin' 'em until they don't work any more

Thanks again.

Baked at 350F for 8 minutes and we're back in business. Yea!

Thanks for the encouragement and how-to from all who have tried this and posted your results.

Got through almost 4,000 pages before my M2727nf locked up during startup. Showed 3 bars on the display and hung there.

Has anyone performed the baking technique more than once on the same P2015 printer? We performed the baking procedure about 1-1/2 years ago. Printer worked great until about a month ago. Started to have issues occasionally, but now is back to not printing and the paper jam light is on constantly. Tried a manual reset per HP instructions. I'm reluctant to try this again, but the printer is useless at this point.

I just finished baking my board for the third time in 3 years: 10 minutes @ 375-degrees. If you are a wine drinker you can save your wine corks, cut them in half then use them to separate your board from the cookie sheet (or whatever metal surface you are using).

I'm on my third bake, too.

One late but no less happy baker from Germany.
After baking I noticed that the board is not entirely flat, so I fixed it only with two screws in the printer. Maybe this tension is responsible for all the trouble...
Thank you, thank you, thank you!

Stuck the board in the oven on 200C for 8 minutes last night and the printer is back in business.

Great thread, great experience.

Fixed and printing up a storm! 7-yr old P2015 that worked fine until two weeks ago. Could only get a connection for 2-3 minutes, whether network or USB. No manner of reset helped. Went so far as to order a replacement laserjet, but decided to make one more attempt, searched Google and found these threads. Baked my board 350F for 8 minutes by my old egg timer, cooled 15 minute and popped back in. It immediately cranked back up and now looks like a champ.

I hate Officejets for lots of reasons, but I still think Laserjets are a fine product. This was my first real hardware problem with an LJ, and the cold weld sounds like a flawed process. The fix was easy, but finding my way to it wasn't. I've tried other laser printers over the years and think they're all inferior to HP. I'll still probably stay with HP for my next laser printer.

Fourth bake! Computer reported my P2015dn was offline. I power cycled it. It stuck on the paper jam light. I baked it 375°F for 12 min. Back online! See my several posts above.

Chalk up one more reflow success. 350F/176C for 8 minutes got it mostly working, but some operations would still cause a reset. A second round at 370F/188C for 6 minutes (followed by a hard reset) seems to have made it perfect again.

For the record, reflow solder profiles typically involve a pre-soak at an intermediate temperature (~150C) followed by a short transient into a higher temperature.

Today I baked my printer's formatter board for the fourth year. See my posts for 9/22/11, 9/11/12, and 7/13/13. This time I pushed the limit and turned the little oven up to 450F. Measuring with my laser thermometer, at 10 minutes, it reached 410F on the green printed circuit board, but 400F for the white plastic pieces, and 420F for the big black chip in the center. Since 50/50 melts between 365 and 419F, I decided to go for the maximum temperature that might be needed and perhaps the lower temperatures might be why it does not last and the times between cooks are getting shorter; maybe I had not hit the flow point. This was the first time I could smell the hot board, but nothing melted, except, I assume, the solder. I put the board back in, plugged the printer in and turned it on, and it flashed through the lights and settled on the amber no paper light. I had paper in it, but it just sat there; I thought I had over cooked it this time. Then at exactly two minutes it cycled again and lit on green; I printed off a double sided page and it is good to go. Funny, since I have gone paperless, I only print a couple of pages a week and I do not want to buy another printer to do that. Anyway it has become a game now. At the rate I print, I have ten more years of toner left.

Thanks for the info. on the oven trick. I have a laser jet M1522nf that wouldn't initialize. I had a repair company come in & they told me it needed a firmware update. They took the machine & they couldn't fix it. They bought it back to me with broken wires on the board & screws missing on the covers & now the auto feed doesn't work, Don't ever call in Office Technology Experts in Melville, NY to do anything to any computer or printer, there butchers. I baked the main board in the oven like other posts suggest & repaired the broken wires & walla, the printer works like a charm. Thanks again for the quick fix trick :)

I sure hope you didn't pay the morons anything. Go on Yelp and give them a bad review. They deserve it. - moe
I'm printing barcodes with my HP printer (I'm using this generator:, but somehow the black bars inside the images seem to be a little wavvy. I changed a few settings but it just won't do. Has anyone got a clue what's going on?

Well, I picked up the HP 2015dn for free and it had this same issue. so I tried the cold reset and that didn't help.

Since i got it for free, I Figured what the hell, try the the oven thing. So I got the formatter board out.

preheated my oven to 350, and set the timer for 7 minutes. (Assuming 1 minute from me to get to oven, grab oven mitts and get the thing out). then i let it cool down (Didn't want burnt fingers).

I stuck it back into the printer and plugged everything back in and prayed.

At first I didn't think it worked because I still had the two lights. But then I Did a cold reset again and it worked then.

A bit scary sticking a board in the oven, but it works.

Thanks to prior posters I now have a working P2015dn laser printer.

Thanks to Mo and all the pioneers and follow up posts. Just to update in 2014, the bake fix still works to fix the issue. Bought my P2015 new (2008?) and the two trouble lights just lit up. Replaced the toner cartridge and the jam light was still lit. No paper jam so I did some research and found your forum. Followed the instructions and it worked perfectly. To those that still have these printers and they fail do to this issue, you have nothing to lose. The whole fix was less then an hour, including cooling time. Thanks for your valuable forum!

toners or ink catridges...what is the best possible choice???!!!
looking forward to ur replies...
by syedfazian on Oct 21, 2014 at 3:51am Add comment
All lights except paper constantly on.
Firstly tried hot air gun 300C. error changed: paper jam light always on.
Then baked my P2015 board 250C 5 minutes and it now works!!!

Indeed, obedient is better than sacrifice! Just a trial convince me and it can be applied to various things that are malfunction in serious of ways because principle of the manufacturers are the same. I appreciated the initiator of this trend and all of you that have contributed earlier. Special thanks to Mr Moe.

Fifth bake and back alive! My toner cartridge is getting low, so I'm just gonna let it run out, and that's it for the P2015. I'm definitely NOT buying a $80 cartridge for a printer that could permanently die at any time. So I'm looking for a new printer. Guess what brand I'm NOT going to buy! HP can go have a personal backdoor love party >:( . (They didn't give me my rebate either!)

Hah, that's funny! Three inches above where I'm typing right now, Google AdChoices is showing me the printer I was most considering as a replacement (Brother HL5470DW; $189 and **** on Amazon).

I use P2015dn to print barcodes on papers.The paper jam indicator stays on even though I cannot find any jams. Also, it is often necessary to turn the printer's power off and on between print jobs to get it to work. Any ideas anyone? Thanks!

Today I baked my printer's formatter board for the fifth year. See my posts for 9/22/11, 9/11/12, 7/13/13, and 3/17/14. This time I was using a new toaster/convection oven and made the mistake of setting it on toast; the top element was on and I did not notice it. I had an oven thermometer set behind it at it read 370F at 6 minutes; all appeared well, but I thought I noticed a faint sparkling on the board. I have done a lot of soldering and when I looked closer I realized that I was seeing the solder hit that melt point where it is no longer cloudy looking but bright silver. I decided to measure the board with a digital infrared thermometer. It read 429F for the big black chip and 417F for the white plastic parte, so I quickly turned off the oven and opened the door. It went down below 90F in 10 minutes, so I put the board back into the machine and turned it on. My computer recognized it immediately, it cycled to the "no paper" light within 5 seconds, sat there for 80 seconds, cycled to green. It then printed normally. I bought this printer in March 2008; I cannot believe that there are still some left. What a piece of crap that I have to put it in the oven five times.

Here's how to do it, remember to remove the black plastic before baking! -1_o1_jUaxATku0ylKHqk
