Hp HP LaserJet P3005

HP LaserJet P3005 hangs during startup

I have a network user who complains that his HP LaserJet P3005 won't print. This printer is attached directly to computer via parallel port.

The user stated that the printer just hung up on one of his print jobs. The user powered off the printer and received an error:
blank screen on the control panel of the printer.

The user powered off/restarted his computer and then powered off/restarted his printer...this time the screen is stuck as:


After many reboot and restart attempts (of both the computer and the printer), the problems still persist:

stuck at a blank screen
stuck at the 048MB***** screen

I have also powered off the device, unplugged power, unplugged the parallel port from the printer and still I cannot progress past the above mentioned screens.

Please help!!
Thanks, Eric
The blow dryer method is the same as what we were using on the JetDirect card. Since then, I've started heating the whole board in the over at 400 degrees for 5 minutes. That yields much better, longer lasting results. At least it has on the JetDirect cards I've used it on. Put the board in component side up and support each corner on something to keep it off the baking sheet or whatever you use. Remove carefully from the oven and let it cool for awhile.
This is for after the service note expires. If HP is replacing the boards, better to do it that way.

The formatter may be the problem. If it has the Toshiba chip at the top left of formatter, HP will replace it.

I can't seem to find any documentation on how to remove the formatter so that I can see if it has this Toshiba chip. The manual has two entries for formatter and neither one are helpful. I also searched HP's site with no success. Does anyone have access to "HOW" to get to the formatter?

Does nobody have any information on how to take this thing apart? I can't find anything in the documentation and am hesitant to just start pulling it apart. Any help would be appreciated. - frieste
If you cannot figure it out then maybe you need to take it to someone. All you do is remove the right side cover by pulling back and out to the right and then the open the cover over the formatter and it is right in front of you.

Most technicians that deal with HP know where formatters are, those of you who are not sure where these are should not attempt to mess with them. The slightest EM shock will kill it. Take it to a service provider.

friest, You have to realize that we have vast experience in this field, and attempting to give a protracted explaination to someone without the actual knowledge is daunting.
Quick, concise directions for immediate repair are meant for those who know what is what, and where. You have been answered , but fail to recognize the simplicity of it. Do you have the ability to turn screws? That could be a deciding factor in supplying you with advice. Do what you were told, and peel off the white label on the top left most chip. It cannot get any clearer. If it is a Toshiba chip, it will be replaced by HP.
If not, then remove any memory,{there's only 1} and restart.
If this is an on-board memory problem, then the formatter has to be replaced.Good luck, and thanks for all the fish.

This is now VERY off-topic, so: First of all, Mr. Righteous, learn to spell. Secondly, what's with the cynicism and sarcasm? I realize that I was answered: I said as much in my last post. Please stay constructive. I don't think asking someone if they can turn a screw is very constructive. I did as I was told already and have taken my printer to be repaired by HP. I really didn't expect to have all this hostility when I asked where a formatter was. I sincerely apologize that I wasn't prepared for the "vast knowledge" and critical sarcasm when I posted to this site. If you are so smart, why would you post to a site such as this anyway? Why not hoard all that knowledge for yourself? I swear, I can't understand why people can't just answer simple questions without injecting their own little brand of "I'm smarter than you are" into every post they prepare. I'm done with this post and will no longer require help from people like you. And by the way, you can keep all your little fish to the future, let's keep it professional and remember what you mother taught you: If you have nothing nice to say, SHUT UP!!

you know all were saying to you is, if you dont what your doing then take it to a service provider. Most of the info on this site in my experience is for techs to supply knowledge to other techs and to give a helping hand to those who wish to tackle simple jobs on there own. As i said earlier, formatters are not to be taken lightly if you have no idea where they are, then dont mess with it. I would hate you to remove it, kill it, then your worse off than where you started. I have removed hundreds of formatters and for the most part there easily removed and replaced, however i have killed them just by touching them. ignore negitive critism and go as far as you can, as long as your comfortable with what you think you can do.
good luck

Any fix for that error? I have a customer that is in MA, and I am in WI. I know the formatters on these machines have started to flake out a bit. I am wondering if I should just send a formatter?
by printertrouble on Jun 25, 2008 at 7:56am Add comment
I took the printer to a local printer shop....all the tech did was "cold reset" it. He didn't charge me for the work since he said he "didn't really do much of anything"....You may have to look it up, but I believe a cold reset is holding down the "check mark" button when you see the memory being tested on the control panel. There is a little more to the process, so I'd look it up. I fail to see how he was able to do that as I couldn't even get it to start testing memory to begin with....oh well, it works and I ain't gonna complain now!! Good Luck!!

-Eric - frieste
Odds are the problem will come back again. The formatters on these units are really bad and I have seen over a dozen that I had to replace due to flakey startup with crazy messages relating to firmware. Just hope for your sake it happens before the service note expires.

Yep, it will be the formatter. Speaking to a couple other techs and they have gotten the same error. The only fix was the formatter. Thanks, Brian

I have a P3005dn which jams every time you try to duplex. Simplex print never jams but duplex every time, and it jams in the bedwith 3/4 inch into the fuser and the rest concertina'd inside. It seems that the fuser stops turning when it should keep going. The paper stops just before the sensor in the fuser.Anyone got any ideas?.

Do you know how to open the duplex tray? May still be a paper scrap in it. Pull tray, plastic lever on the right, push to open, lift to close. Paper size setting may be wrong.
Timing issue.

GOOOOOOOD NEWS on the formatter boards that are hanging up at the memory count or before READY comes up. It is the defective TOSHIBA chip on the top middle of the formatter board & usually there is a white sticker over the chip. I confirmed it 100\% !!!!
But the bad news is HP will only give the extended warranty to the serial number range which is listed in a post somewhere on this site; I think starting with CND----?? So I called a local warranty center & luckily the guy knew how to look up service notes & said the note is DOC #C01215806 but my printer did not fall under the range & so I was out of luck. ---- So, since the new formatter is $296 from HP & they are on back-order there was no loss in trying the experiment listed previously. My P3005 printer would only get to the ready state once in 20 power on's & then hang when I tried to even run a test page. So I opened the right side doorways to expose the formatter & put a good hot blow-dryer up to the bad chip on the top middle & let it get good & hot & turned on the printer -- it booted but the display was lit but blank & stayed blank. I kept the heat on & re-booted the printer again & the display then stayed black with no light at all & I thought well I am getting somewhere. Then, without the blow dryer I booted it again & still got the dead display -- no light at all. I let the formatter cool for 3 minutes & re-booted & then got the blank display with light; then I knew I didn't destroy the board but the plastic casing above the formatter got a little warped from the heat -- just barely. Then -- by desparate means-- anothe re-boot & the memory counted all the way up & it went to ready & printed. Now it works on the network again & after 4 days it boots up 85\% of the time & prints normally. BUT, when it goes to sleep mode it will not come out of sleep so I have to re-boot it then. Sorry for this long story but it may be worth $300 to someone else. Dave L. Utah.

I find all this very interesting that a company like this can send out JUNK and expect people to pay another $300. I have the non-Toshiba chip and get ALL of the issues listed abover. My machine was built in June 2008 so obviously, there is issues with software and hardware. I thought HP was better than this but in a world of fast bucks and no customer support, I guess this is what we have now. Maybe when their stock price tanks they will realize that the customer is more important that quarterly profits. By the way, not interested in causing a fire with a hair drier every time I want to print something. There a song about this, M I C K E Y M O U S E. Thanks Walt.

--- Even better news --- to 3 posts up. My P3005 worked for 5 days after the blow drier fix & then went back to memory errors & a blank display, etc. so I took it into my warranty center mentioning a service note & they looked it up & said all serial number ranges can get the new formatter if the display is lit but blank & mine does this half the time at boot up. So I got a new board for no charge & it works great again & the warranty center thanked me for teaching them something new about service notes.

Lit but blank display... Anybody know what the service note is for that one? - tcholmes
You need a new formatter board for the unit. Blank Display, freezing during memory count/initialization, and dimm errors all require the new formatter. Upgrading the firmware has been known to help in some cases....

I went through all of these troubleshooting but no result. I read somewhere to heat up the motherboard. I borrowed our facilities heat gun, set the gun to 1200 Degress High, shot the the back side of the formatter for 5 minutes, specially the other side where the memory was and viola they work again. Concentrate, when shooting, where the solder points are. I just fixed 3 of them. This works ladies and gents.

I had a printer that hangs during startup so I baked the formatter in the oven at 170 degrees Centigrade (we use Centigrade in the UK) for 8 minutes and it worked fine.

Thanks for all the help that this site gives.

Had the same problem, checked the basic stuff and called HP support.

Usual guarantee is 1yr (according to HP), but with these kind of problems (production error or something like that), +1yr extra guarantee.

Printer kept hanging in different stages of startup (where the animation on the display and shows 024MB, 048MB, 065MB, 1/6 2/6 3/6 4/6 5/6 etc, stops at any point).
Did some tests, like pressing+holding the green V button after it starts memory counting, but to no avail.

Opening the right side of the printer (slide it backwards), opening the metal cover and checked if extra card is installed in the white slot (there wasn't any extra memory installed in mine), closed the metal cover (but not the plastic one)
Then use the test button 5cm below the fan (can only be seen with the right side panel slid off), it produced striped output.

With this information the HP technician concluded it was a 'formatter error', printer will be replaced for free.

If HP wouldn't have provided the factory guarantee, I could also have used my legal guarantee (Europe > 2jrs(minimum!), probably a lot more), but I prefer HP as I know they care for their customers.

HP has noted that there is a firmware problem which results in corrupted flash memory. They have an updated firmware which should be flashed to any p3005. It must be flashed twice to have a good upgrade. If you have any of these which have not yet failed, you should insure that the firmware is updated.

They are also extending the free replacement/repair of these units, so HP support should be able to fix you up if you contact them w/ the particulars.

Funny - all the garbage about the bad flash chips, bad BGA installations, and ultimately it comes down to HP actually programmed them all to fail. - unknown
Bull. If the baking of the board corrects the problem then the issue is the main chip with cold solder joints and nothing else. I have personally repaired over 20 of these boards with baking and everyone of them is still working. The problem is cold solder joints and nothing else.

"They are also extending the free replacement/repair of these units, so HP support should be able to fix you up if you contact them w/ the particulars."

I was recently fobbed off by HP for not having bought the extended warranty on the unit. Could you please advise on how to get them to push it forward?

We are a business, and I had thought we had a 3 year carepack on these units but apparently in my 1-week absense they weren't procured. Typical.

Rather than banging your head against the proverbial wall, it's a lot easier to just remove the 4 screws holding the board in, disconnect a few connectors and bake it in the oven. Whole job takes about a half hour including letting it cool off. Not worth the aggravation of dealing with hp and all the levels of tech support, mgt. you have to fight through and all the hours of time you have to spend on it. - moe
OK, I'm getting to bake the board but have some questions. There a few hundred small parts on the bottom side including 3 ICs so what keeps them in place when the solder flows? Surface tension or are they glued down? There also seems to be a bit of discoloration around the large BGA chip, is this normal? Thanks.

The P3005 has a history of bad formatter boards.
Replace the board.

I have heard many stories of "baking" the board, with various recipe's of temp and baking times.

All I know is that there is no way that I would ever use my oven for food, after a circuit board has been baked in it!

Duh! I'm sure that I get enough toxic exposure in my daily life, without trying to save a buck by contaminating my oven!
by unknown on Mar 29, 2011 at 8:24pm Add comment
Well I use my food oven after baking boards with no after effects, so far. I have baked many of these boards very successfully.

The recipe is to heat the oven to 170 degrees Centigrade, when it has reached that temperature put the board into the oven on one of the wire shelves with the components uppermost, close the oven door and leave it for 8-10 minutes to reflow the solder connections.

After the 8-10 minutes turn off the oven and open the door to let some heat out to cool the board a little allowing the solder to set then remove it from the oven (with heatproof gloves or similar!!). Place it somewhere to cool for an hour and reinstall it.

170 degrees Centigrade is 338 degrees Farenheit.

This proceedure can be used for network cards, main boards, dc controllers, etc. Anytime I get a suspect board of any description this is the first thing I do. You would be surprised how many boards you can fix this way.

So I put the board in the oven 170 centigrade. After about three minutes in, components starting melting and this thing is toast.

I'm not sure how you all can successfully bake the board but I must be missing something here or I just misunderstood.

Now to air out the house....

Either your oven is messed up or you put it in broil. I just baked a board after a yummy batch of chocolate chip cookies. I'm going to try it tomorrow and have no doubts about it working. I even brought an LCD panel with no display back to life yesterday. I was kind of afraid of the plastic face melting, so I hit it with a hair dryer instead. Sorry you toasted your board, but with the all the success stories, it must have been something you did wrong. I've lost track of how many boards I've brought back from the dead. - moe
Did you put it on the middle shelf and turn the oven on and not the broiler? It should not have melted it.

170 Celsius = 338 Degree Fahrenheit.

I took my board off my printer and was getting close from the baking in oven but just wasn't quite there towards fixing it. So I wrapped it in aluminium foil and cranked up my concrete pizza bake oven to the max heat that usually does my pizzas in under two minutes, then put my now wrapped board in there for seven and a half minutes and now works flawlessly.
If you have the same problem as I did and have the privilege of either having a pizza oven like mine or a very nice and modern fan-forced oven you will be able to get a fix. If you have a powerful fan-forced oven I suggest eight minutes in there at 220 degrees Celsius.

Thanks for all the constructive help on this forum guys =)

Should I use Parmesan or Romano chesse when I bake my formatter board?
by unknown on Feb 8, 2012 at 8:07am Add comment
Heating the board to 170C for 8 minutes does work - it has for the board in my p3005, that had the same lock up problem as noted above.

However, that temperature would be risky for some of the components on the board - specifically the larger capacitors and the Li battery. When I did this I took the precaution of desoldering them from the board, doing the baking, and resoldering them (make sure you pay close attention to the polarity on the caps and the battery of course. If you are not comfortable doing this you can take a chance baking the board, but I suspect you may see the capacitors leaking and the battery failing or worse.

Baking boards is a time honored method in board manufacturing, and probably is a good idea for this problem too.

Good luck!

This is a very common problem with this machine. You can officially replace the formatter board to fix the problem.

The baking of circuit boards is not a manufacturing step unless you are referring to the Wave Soldering process. Boards are baked after the manufacturing process as a Quality Control function, we would conduct environmental testing in which the boards were heated and cooled while being tested to ensure they will function while in various thermal and physical environments.
by unknown on Mar 13, 2012 at 11:07am Add comment
What is important is that baking the boards will give an extra year of more of life. The board isn't functioning, so there is no down side. The upside is that it is a free repair, not including the pennies to heat the oven. Why would anyone in these tough economic times, prefer to spend good money to buy a replacement formatter for such an easy repair involving 4 screws and less than a half hour including cool down?

Has anyone ever came across an issue with replacing multiple formatters in a short time for the same issue? I have one in particular that has had three seperate formatter replacements over the past year, and after replacing the third one a week ago, it again has to be restarted to get it to print (only one account). I have not seen any freezing yet, though. Before I replaced the third one, it was freezing on the memory count. I also found the power cable plugged into a cheap dollar store surge protector, and the network cable had a few kinks in it, so I fixed both of those issues as well. Yet, it appears to need a fourth formatter. The RAM gets carried over so it almost seems obvious that is the issue. But if the RAM is the issue, you would think the problem would still happen immediately after replacing the formatter. I'm going to try the DC controller for the fun of it..

I don't know where you're getting your replacement formatters from. Perhaps they aren't new. In any case, why are you replacing them? I get longer results from baking them and it costs nothing except a few pennies of electricity for the oven and minutes of my time. - moe
The company I work for gets our HP parts from Parts Now. They appear new, but who knows I guess.. The first two were replaced by other techs, so I'm not exactly sure of the symptoms. My symptoms were the user had to restart the printer to get it to print and then it would freeze on the memory count. The typical signs. Personally, I'm not okay with baking electronics in the same oven I bake food. Also, I've had mixed results with the baking method, some work fine, some fail. Since I work for a larger company, we're graded on call backs, I just try to avoid anything that can give me a call back, including baking/heating the boards.

I doubt there is a vendor out there that is selling a new unused formatter. Easy to tell. When you get a replacement run a config page and see what the serial number and page count are. If the board is one that has never been used the serial number, page counts and network settings will come to the new board from a backup chip on the dc controller. It will even have the model number since the same board is used for duplex and non duplex models but model ID'd when the new board is installed. If the board you receive does not do this, then it has been used before. Most of these "used" boards are taken from surplus printers and sold as duplex or non duplex depending on the model it was taken from. A duplex board from a used machine put into a non duplex machine will make that machine duplex. I have baked over 75 of these boards over the last 3 or 4 years and maybe had to replace or bake again on only 2 that I can remember.
by dmzcompute on May 9, 2012 at 5:08pm Add comment
DMZ, according to HP, the proper procedure for replacing a formatter (to ensure the serial/meter/etc. are copied over to the new formatter) is to:

1) Turn printer on
2) Let sit in "ready" state for 15 minutes
3) Power cycle
4) Let sit in "ready" state for 15 minutes
5) Power cycle
6) Let sit in "ready" state for 15 minutes
7) Print config

Really, I'm not making that up. HP says this allows the DC controller to communicate with the new formatter and apply the previous serial/meter/etc. data. - luttrell
here in australia, whenever i ordered a new p3005 formatter board from a hp authorized parts outlet, it always come with a ram board. and i've not yet come across any new board gone bad yet (fingers crossed).

baking, on the other hand, i've the same mixed results as you. infact i've more failures than sucesses. that's why nowadays i only quote new board for repair. not worth mucking around. it's only going to cause more disputes when they failed again, and impact on your company's reputation.

I have done many new formatters and you only have to wait 5 minutes at the most after it comes to ready for the printer to transfer the information. You can do any of the other items, but once you have waited 5 minutes after the first power up all the information has transferred.

Just pop it into the oven while it's warming up for say, a pizza and take it out when up to temp. However, even though this model isn't that reliable, it's still way better than the junk that Lexmark produce. Anyone who buys Lexmark deserves to have it shoved up their arse!

Another half baked idea turns into full baked success! So-far.

I got my printer when I bought a business last year from an interesting woman. I would have jsut dumped the printer and gone for an updated model. However, she somehow, for some reason, had bought about 20 perfectly good toner cartriges for the printer which I received for free - far more valuable than the printer itself. Needless to say, saving the printer had some value.

I was experiencing the same issue as others posted here. Printer started to go off-line, no menu function, and had to be turned off then on again to get it to work. Eventually it would not boot up at all without hanging up during initialization.

So, I tried the baking of the format board and it started right up and appears to be working fine.

On first boot up I had to reset the date and time so perhaps the battery got fried in the oven. I didn't want to bother try to de-solder the battery and put it back on. I will verify the next time I cycle power.

Thanks for everyone's postings here.

You might want to sell the cartridges that you're not going to use in the next 3 years as that's about their shelf life. After that you're going to experience wiper blade deterioration even in a factory sealed box and that will result in toner streaks after the first few pages. - moe
Thanks Moe,

The cartridges that I have are all out of date. Someone had already gone through all of the cartridges (about 50 actually) and returned all of the eligible ones. I am just trying to salvage what I can for as low a price as possible = $0.

Fortunately I have not experienced any problems - so far. When I do, if it's not a quick fix like baking a board, then off to the trash heap it all goes.
by unknown on Aug 15, 2012 at 11:39am Add comment
In my experience, the baking lasts about a year and it's repeatable.
The only other problem you're likely to experience is the fixing film and we have a low cost kit to repair that. - moe
The best place for a P3005 that "hangs" is just that...hanging from a rope/chain into the ocean, as a boat anchor.

Has anyone noticed that with the P3005's add-on tray 3 feeder, the tray 3 cassette cannot be swapped with the tray 2 cassette? What kind of goofy BS is that? This is the worst design I've ever seen.

Also, the newer HP trays are made with tiny, cheap, fragile plastic parts that always break. Who came up with this garbage? HP must think their customers are absolute fools.

In my business I have 3 HP P3005dn printers, 2 of which had failed in different ways during startup. No amount of resetting or retrying made any difference. I was about to throw them out when I came across this thread. What the hell, I thought, they're dead anyway -- so last night I took out the formatter boards, preheated the oven to 350F and baked the boards for 8 minutes on a preheated cookie sheet covered with parchment paper. I did remove the snap-in DDR memory board, but did NOT remove the battery, capacitors, or anything else. The house smelled vaguely of overheated electronics, but there was no obvious damage to the boards. I reinstalled the boards this morning, and BOTH printers now work perfectly!

It really works.

cook it! the printer does not work anyway, so what do you have to lose. Make sure you leave the board overnight to cool natural.
done it a few times on this end, works well!
by unknown on Nov 7, 2013 at 5:40pm Add comment
A simple test. After opening up covers to expose formatter, Press the chip on the top left side as you switch on the printer. Maintain continuos even pressure as printer boots.You will realize that it wont freeze and will fully boot till ready. The moment you release pressure it will hang as before. Thats a good test for the culprit chip. Other chips can be tested as well.
A perfect way to avoid the oven. Remove formatter. Apply solder oil on both the leads of culprit chip. Using a small solder gun or hair drier or preferably hot air equipment, apply even heat on the leads as you press down the chip. The old solder will melt and reconnect the chip.
The failure of P3005 is attributed to vibrations that the powerful motors produce during operation. Not heat as earlier mentioned because formatter is surrounded with metal that keep away the heat. over time solder connecting chip leads and printed board crack causing disconnection. The process outlined here simply melts back the solder to reinstall connectivity.

I had the same issue, even with a non-toshiba chip, it seems to be a relatively recent board. I did some baking during 6 minutes about 175 C° and it went great. The printer is up and running and I hope it will last more that one year.

Somehow, i don't think that "hesitant" equals "can't figure it out"....i don't know if you're being cynical, but I don't appreciate it. I just don't like taking things apart without instructions. Thanks for your input.

Again, I appreciate your concern, but I am not an idiot. Simply answer the questions put before you and stop putting in your two cents. All I ask is a simple question that few people really answered. Is this a forum for asking questions or is it a forum for showing others that they don't really know what they're doing? Please stay constructive and ANSWER the QUESTIONS!!!!!!
