|I've just been given an HP4550DN with a JetDirect 610N card.|
The previous owner said the printer would "occasionally lose network connectivity".
The printer powers up and runs the self-tests successfully.
But when I want to configure the JetDirect through the front panel, all I see are parallel port I/O options. There no menu items for EIO.
I tried moving the 610N card between EIO ports 1 & 2, but it doesn't make any difference.
1. Am I overlooking something obvious ? - Yes, I did read the manual but it was pretty vague in this area.
2. Is it likely that the JetDirect card has died and needs replacing ? Is there any other way to test it ?

|Its a bad jetdirect card, I'm sure if you look on the configuration page under installed options, the 610N isn't there. You'll have to replace the card if you want a network connection again. In my experience doing a cold reset to the printer didn't help in the long run, card always came back & failed eventually if it started working at all. You could send Moe an email he might have some 600 series cards, those work great still. |

|I ran out of 600N cards. Had 2 610N and 1 615N cards go bad in the past week. Too bad they weren't all 615Ns as HP is still replacing those free. All I have in stock at present are 620Ns and they're all brand new.|

|Ok folks I was told an old trick to get the 610N working and believe it or not out of 7 bad cards I acutally go 5 of them going and they are still working. Here is what you need to do. If you place the card down with the connection to the printer in front there is a big black chip labeled Phillips Arm. To the left is a small silver piece which looks like an old crystal piece. Now you need to get a real good hair dryer which puts out hi temp heat. You then need to point the hair dryer putting it close to the chip in the left and front corner of the chip and keep heating it for 1 to 2 minutes at very high heat. There are solder joints below the chip which you can not reach and evidently a couple of them become cold joints and if the hair dryer is hot enought and you keep in pointed at that location for the alloted time it sometimes repairs the cold solder joints. I would like to see as many people post back there resutls who try this either with success or not just to see if I am imagining the results I got or it really works good.|

|Hairdryers won't work. They don't put out enough heat. You need an industrial heat gun that puts out more heat. I tried it on the 2 I had. The printer wasn't seeing either one before I heated it and it came right up on the display afterwards. I heated it for 10-15 seconds. The industrial guns cost about $200. I got mine for $7 at an auction. I had 2, but one broke. The new model has a nifty LCD display and variable temp settings. Mine just has cold and "start fires" settings. I guess I can't complain for $7 and over 10 years of use.|

Some hairdryers might work.
I checked with my brother who has an engineering degree, but I think the heat gun would be better.
DMZ fixed his with a hair dryer.

|I just assumed that since you couldn't get yours to work that it was because the hair dryer wasn't putting out enough heat. It takes a lot of heat to melt solder. I wouldn't trust using a soldering iron in all that delicate circuitry. Too easy to slip and wipe something out. Didn't know dmz used a regular hair dryer on his. I've had several and some put out more heat than others, but the mfgs. don't want them getting too hot because some dummy will set his hair on fire and sue. I'm saving up for that nifty digital display one. Love my toys.|

|Its my sister's conair deluxe model and it puts out a lot of heat. One of the hotest I ever encountered. I first tried to hold the card by the back where the rj45 connector is located and the air dryer was so hot that I could not hold on and had to lay the card on a hardwood floor and point the air dryer at the area in question.|

|I can add my thumbs up to this trick, although I read about it on HP's user forum. Used a hairdryer (a Revlon 1800 watt model) to bring my JetDirect 610n back from the dead: just heated both sides for about 5 minutes each and it worked!|

|Had the same problem here with my HP2200D (not sure what board it is, parallel, iR and USB interface), same story, big square BGA (Ball grid array) chip and intermittent failures ( all 3 lights fixed on permanantly).|
Hit it with the heatgun for about 2 minutes at 300'C and 5cm away, waving it around a little to warm up the board, then flicked over to 500'C at about 5cm from the board, working around the edges of the chip a bit too for another minute or two then left it to cool.
If it doesn't work, try again for a bit longer.
Now I can hope to see another couple of years out of this very reliable printer.

|This trick worked for me today on a 610N - 4100TN Laserjet.|
About 2-minutes of hot air from a Revlon 1850 dryer, let it cool for a min or so and put it back into EIO1. Jobs started printing right away.

I only had a 1250 watt hair dryer.
Just covered some of the air intake with
my hand and ran it at low. Got nice and hot.
Couple of minutes, both sides on a HP 610n jetdirect.

|The fix worked perfectly for me! At the university somebody throwed away a HP Jetdirect 610N. I picked it out of the recycle bin and took it home where I put it Into my printers. It wasn't even recognized :-( So I saw the hint with the industrial heat gun here and just gave it a try, and it workded perfeclty! Two thumbs up. This cold solder seems to be quite often a problem as I got my dead iBook back to life using the same method :-)|
I had a 2000W Black&Decker heat-gun and pointed it at the maximum temperautre for about 10-15s just above the Philips ARM Processor. As soon as the plastic of the Printer-Connector began to melt it stopt it. Perhaps a heat-gun with a smaller output hole would have been even better for this job, but the card works now anyway.

|Fantastic Fix. It certainly works. Thank for finding and posting it!|
I did it with a hairdryer too.
It's interesting to think about why this fixes the problem with this board. A cold joint can be only fixed by heating it with a soldering tool to the melting point of solder (360 to 370 °F) so that the solder reflows.
I don't think our hot air blowers, as hot as they are, are hot enough. If they were then the small surface mounted components nearby would be loosened and blow off.
I suspect there is some other flaw with in this chip that is somehow "repaired" by the application of heat.
In a quick search of the web, I cannot find any other descriptions of cold solder joints in any other devices being fixed by hot air. In fact if you Google the words "cold solder joint hair dryer" you get this thread as the top result! None of the other top hits tell of similar fixes. Lots of diagnostic testing with head and using heat shrink tubing, but no fixing cold joints.

|That's how they solder the surface mount chips in the factory. Did you think they did all the soldering with a soldering iron? They put the chips on the board and hit it with hot air. I remember seeing one of the industrial units once at an auction.|

|As far as I know, HP is still replacing the 615Ns with new 620Ns under an extended warranty. Otherwise, it might work. The way I see it, the card is dead. Heating it up couldn't make it any worse. It will either resurrect it or it would still be dead.|

|Add me to the list. Th HP printer's EIO port stopped recognizing the jetdirect and showed a solid activity light on card. Using a heat gun got it working. I had my doubts at first, but after heating it for about a minute on top and a few seconds on the bottom it worked. The heat gun was strong, so I used low heat about 4" to 5" away from the chip. I wonder how long its going to last? Thanks for everyone's input.|

|Hi everyone. My brother's lab does a lot of custom prototyping with multilayer boards and surface-mount components, so I talked to him about the heatgun method after my 610N died. Turns out he uses a precisely-controlled oven for his soldering; he says he'd be worried about hotspots with a hairdryer, not to mention the possibility of literally blowing the tiny surface-mount resistors off the board once their solder melted. He says it's not at all uncommon to have bad solder joints due to inadequate amounts of solder paste applied to a few pads before the components are stuck on.|
- preheat my kitchen oven to 400 fahrenheit (mine has a reliable digital readout - a thermometer would also work)
- remove the plastic bezel and any stickers from the 610N card
- arrange for some kind of support to make sure the top and bottom surfaces of the board are horizontal and completely exposed to air (I found 4 screws that fit the holes around the outside edges, attached them so the board looked like a low-standing coffee table)
- quickly open the oven door, pop the board in, and close the door
- wait 5 minutes (not much more than 6) for the board to reach 400 degrees
- open the door, very gently remove the board (solder will be liquid at this point, but surface tension should prevent parts from slipping around if you're careful), and let it cool down to room temperature on its own
- re-attach the plastic bezel, and put it back in the printer!
My 610N that I had totally given up for dead has now been working perfectly for a month, thanks to all you guys. Hopefully this alternate method will prove useful to someone...

|Hi Everyone - |
Tried the hairdryer routine on my dead JetDirect 610N (on an HP 4100N) and it brought it to life for about 2 minutes - as soon as it cooled down the connectivity was lost again. Would baking it provide better results? (The reason I didn't do this first is that the plastic bezel is held on by some screws with weird phillips-type star head screws - no idea where to find a proprietary-looking screwdriver like this.
If not - do they still make el cheapo parallel port print servers?

|I tried the oven method with an apparently dead JetDirect 615n, after a cold reset failed to make the card appear in the print configuration printout.|
I put the JetDirect on a plate, horizontal position, chip side down. Then I baked it for five minutes in a preheated oven at 350 degrees.
That fixed the card, but it melted the tan colored molded plastic that forms a handle for inserting and removing the card. Removing that warped plastic took a while. While the handle per se is not necessary, the same plastic piece projects across the back plate to receive two little Torx screws that hold the card in place. I eventually managed to cut the rest of the plastic away and left just the plastic 'nuts.'
Installed the JetDirect, followed HP's instructions for using telnet to access the card's setup at 188.8.131.52, changed the IP, and now it works fine.

|The oven trick is well documented and if you had read previous posts it tells you to remove the back plate before heating and also to prop up the card using screws or whatever in the 4 holes one in each corner. Also the recommended temp is 400 degrees in a convection oven for 5 minutes. Remove a let cool at room temp before putting back together and trying.|

|Thanks, dmzcompute, for reiterating the basic instructions for the oven method; people are not likely to backtrack to the original post. Since being baked almost a year and a half ago, my 610N has worked flawlessly, and I don't even worry about knocking on wood anymore.|
By the way - after the 5 minutes are up, it's somewhat safer and simpler to just turn off the oven, open the door all the way, and let the board cool off in situ; doesn't take that much longer and there's less chance of burned fingers or slipping components.
About the recommended temperature of 400 fahrenheit: The various lead-based solders melt somewhere between 350 and 400. Lead-free solder (which melts at much higher temps) wasn't really in use before 2006, so it seems probable that any 610 board will re-solder itself at 400 without getting fried. If you're worried about heat damage, maybe try 375 the first time and bump it up if the board fails again later.

|Personally, I stand amazed. I baked my 610n board at roughly 400F (my oven sucks, and the thermostat is wildly inaccurate) on an oven-safe dish of just the right size to suspend the board off the plate surface by the board's corners. By the way, the two little screws holding the back plate on are called Torx head screws. I opened the oven and turned off the heat after 5 minutes. I let the board cool in the oven for 10 to 15 minutes before I removed it. Then I took it outside on a cold Fall day in the Northwest to let it cool faster. After about an hour, I put it back in my LJ-2200, and the dang thing came right up. It still had all its settings.|
I've frozen hard drives in last-ditch data recovery efforts, but I've never baked a populated PCB -- or any PCB, for that matter -- and had it not only survive, but actually function as intended. That blows my mind. I paid $10US for that card a few years ago at a local technology refurbishing/recycling shop, so if I get a further year and a half of functionality, I'd say that I more than got my $10 worth.

|Had a JetDirect 615N card that had died - printer couldn't find the card anymore. Printer was outside of warranty, and the card itself was just outside of HP's JetDirect replacement program.|
I was planning on buying a new card, but stumbled across the "oven method" on another post, which led me to this forum.
As described above, removed the plastic backplane on the card, suspended it in an oven dish and placed in an oven pre-heated to approx 400F (205C) for five minutes. Then opened the door of the oven and let it cool gradually.
Re-attached the backplane and put the card back in the printer. IT WORKS! Thanks to all of you for this info. Saved me a few bucks buying a new card if nothing else.
I'm guessing that HP's soldering on this card is fairly dodgy, and that the solder joints crack or something after a while (maybe due to thermal expansion after the card has been used for a while...) Obviously putting it in the oven causes the bad joint to re-flow and come good again. Typical HP hardware...
Thanks again :-)

|Gilles - I've only baked one 610 card; I believe others in this forum have much more experience with them. But I can tell you that mine is still functioning perfectly, and it's been close to 2 years since its date with the oven. Before that, I had revived it several times with a hairdryer but it always failed again within 24 hours; I'd like to think that this means that the original faulty solder joints were permanently repaired, but I guess I'll never know for sure.|

Your Mileage May Vary....these faults are clearly the solder joints, and there is no way to tell whether the same joint or some other one is failing each time.

|Wohoo, this is awesome thread!|
Tank you dmzcompute for your info, tried with a solder torch, worked ok for 30min or so. Torched again, worked for a moment and died again :/
Then took the extreme measures and baked that card for 5min in 200 celcius, and now there is a shortcut some where, printer wont boot with the card inside, lol.
So to awoid shortcuts after baking, shut down oven and leave door open for a while, dont move that hot card untill it has coolen down a bit ;)
Will give second card a go tomorrow :)

I've got a second-hand 4550DN in excellent condition with only 8,000 pages through it, and fitted it with a replacement 610N card off eBay that came with a test page to show it was working. The original card didn't show up on the config page even after a cold reset.
I simply can't get DHCP to work, and I can't seem to access the manual IP setup either.
I've followed the HP instructions on bpl08785 for setting up DHCP several times, both on and offline.
I've cold reset several times.
I've tried every combination of TCP/IP settings apart from a manual address which, as I said, I can't seem to access.
On the config page (and I've got dozens of them) I get-
DEFAULT IP CONFIGURED
CONTINUING TO DHCP
Host Name: NP153556D5
IP Address: 192.00.192
Subnet Mask: 255.255.255.0
Default Gateway: 192.00.192
Config by: Default IP
BOOTP/DHCP Server: Not Specified
TFTP Server: Not Specified
Config File: Not Specified
Domain Name: Not Specified
DNS Server Not Specified
WINS Server:Not Specified
Idle Timeout: 270 seconds
Web JetAdmin URL: Not Specified
Firmware version: L.25.08
I use Macs and Mac OS 10.5 and below will see the printer using the AppleTalk protocol, so the card works, but 10.6 does not have AppleTalk so I need to use DHCP. Apple's Bonjour will see the printer but won't print to it. As the printer is a bit long in the tooth that's fairly understandable.

|Thanks dmzcompute! We had 2 cards that had gone bad within 1 month. I tried the hair dryer and it indeed fixed 1 of them! I would never have thought to try this on my own. I have heard the oven trick works on some too if the hair dryer isn't hot enough. Might try the hair dryer a bit longer on the other one first before I try that. I'll put another post up here if that works. Thanks so much!|

|Off topic, but I just did the same trick with the mainboard from a Samsung LN37N550 LCD TV. TV was kicking in a protection circuit which would switch it off whenever we connected a signal...|
I was ready to order another one on Ebay, and as a last resort I put the mainboard in an oven at 400deg for 4 minutes, and it has been stable since!
In the future, the last step before sending any board without visible damage to the trash is to bake it in the oven....you never know!

|The oven trick worked like a champ for me - I had a 615N that had quit working altogether. I fashioned two wire supports from a coathanger, and baked in the oven for 5 minutes @ 400 Degrees F. The only trick was that the supports were not perfectly level, so one of the larger surface mount resistors or capacitors (don't remember which it was) slid out of where it was supposed to be slightly. fortunately it was still making a good solder joint. I allowed the board to cool for about 10 minutes, unplugged the printer, put the card in, powered the printer up, and immediately two print jobs printed off - it never lost its settings!|
So, make sure your support (whatever you use) is perfectly level, and you should be fine. If you can afford the time, I would even open the oven door and let the board cool in the oven with the door open, so that you don't run the risk of parts shifting while the solder is still fluid.

I ovened 2 610N's (not recognized at all) and a 615N (recognized, but saying that the f/w upgrade was incomplete) at 375 F for 5 minutes and now they all work perfectly.

|I have an 8 year old 4100n with a 610n card that lost network connectivity last week. I determined that the NIC card had failed , so I bought a new card from e-bay($25.00) and got the machine working again.|
During my research as to how to repair the printer I saw several oblique references to "baking" the card. I found this thread and decided to put the old card in the oven @ 400 degrees for 5 minutes.
I put the old card back in the machine and it functions perfectly.
Thanks to all.

|Well I own a computer shop in East Stroudsburg, Pa and i use an HP 4100n for my b/w invoices everyday for years.. I have it networked in obviously so i can print for anywhere in my shop.. Well Just 2 days ago my printer would not print ...no network.. So i did the obvious cold reset and it would just keep getting stuck on the dual asterisk bars and never go to ready... Well after pulling the jetdirect and unplugging and plugging back in it worked fine.. therefore i knew it was the card.. |
Well i found this forum and thought i would try it.... first with the hairdryer just seemed like the safe way...
i used a 1875w hair dryer for 5 minutes and nothing
So i tried the Baking trick using 2 toothpicks in each corner to suspend it up from the baking dish and hold it level
375degrees for 6 minutes and a gradual cool down about 10 minutes
SURE ENOUGH IT WORKED LIKE A CHARM THANKS ALOT

|This worked for me recently: 615n, had been completely dead. 375F for 5 minutes in toaster oven.|
It seems like the success rate is close to 100% as reported by others here.
Does anyone have ideas about the limitations of this repair method? Only appropriate for surface mount devices? Any different recipes for different board types? Any recommendations for a good wine to go with a freshly baked 615n?

I was wondering just how elaborate this hoax was to generate such a long list of testimonials. But after I found the same fix in 3 or 4 other places I decided I had nothing to lose. My decade-old LJ 2200 network printer is back in business. Hurraayy!! I don't have to reconfigure printing on all my computers.

The 610N had all lights on solid green, and there was no menu selection for the EIO card. All internet research pointed to a bad JetDirect card. I spent 15 minutes looking at Amazon and ebay to buy a new card, and by TOTAL luck I stumbled upon this fix.

|This baking procedure worked for my JetDirect 615n that was not being detected at all in my HP 4050N.|
Preheated oven to 200 deg C.
Removed plastic external shield from 615n card.
Used 1" bolts with nuts to space board horizontally off oven tray, with chips facing upwards.
Baked for 5 1/2 min.
Turn oven off, open door, allow board to cool.
Reinstall plastic external shield.
Now it works.

Now let's see how long it lasts. When I powered the 4050 back off and on again it didn't recognize the 610N. I had to put it back out and give it another shot with the hair dryer to bring it back to life.
