Hewlett-Packard LaserJet printers use several models of network cards with same typical failure after several years of work. Those are cards HP Jetdirect 600N, HP JetDirect 615N, HP JetDirect 610N
Easy fix with almost no tools available:
- You get hair dryer and heat BGA chip for 10-15 minutes
- Let it cool slowly without moving.
- Test it in the printer.
- Leave comment including model of your card and printer here.
Usually those 3 steps are enough to make it work again.
If you are for example graduate student and have wonderful toys to play around such as temperature controlled furnace you can do the following:
- Remove white plastic top plate with name of the card on it.
- Place card horizontally the way it suspended in air inside furnace (see picture)
- Heat it to temperature of 160C (320F) for 15-20 minutes
- Let it cool without touching
- Test it in printer.
- Leave comments here including model of your card and printer.
Good luck champions! :-)
Hard to believe it but I was given an HP 2200 series with the inevitable dead Jetdirect card. I've seen more dead JD cards in my time than I can shake a stick at. I tried baking it at Regulo mark 4 for 15 mins and, hard to believe it, but it's now working! I did have to reseat the card and reboot the printer twice but it's now installed fine. Thanks for the tip!
ReplyDeleteI have been heating my 610N chip with a hair dryer for 2 minutes for more than a year and it worked great for quite awhile. Then, the card lost connection many times a day, increasingly. Now, heating it no longer works. I tried 5 minutes, but that didn't work. I'll try 10-15 minutes, but meanwhile, bought another jetdirect card. Don't have the time to mess with this problem over and over.
