HP 2100 Service Error 3 lights, troubshooting

[Bigears]

Hi all, my 2100 was working great, maintenance kit installed about a month before, 35XXX copies on the clock. Now I'm getting the dreaded 3 light service error. I've reset it by leaving it off for 24 hrs and then it will print one page fine and goes back into error mode. I have to leave it off for at least 12 hours before it resets, but then it always reboots with normal lights until it prints one page. I tried to reset it with the go button but no different. Paper path is clear.

I have a high mileage 2100 that works. I switched the formatting card, and no difference. I'd have no problem using my 775XXX page working printer for parts.

Thanks!

We have a lot of 2200's here which are very similar to your 2100. About the only thing you can do with these is swap the formatter, which you have done, pull the NIC if you have one in it, then try the fuser. Since it does print one page the fuser is a good possiblilty. It also has a paper path sensor in the fuser which could be the culprit. If it is not the fuser then it probably is best as an organ donor. You could get a replacement printer for far less than the main board under the printer and changing it is no picnic. Good luck!

Thanks for the info. I had considered that the main board was bad and you confirmed what I expected, it is a lot of work to swap out. I will swap the fuser with the good printer and report back. If that doesn't solve the problem, I will swap the maint kit parts to the high mileage working unit and keep the other for parts I guess.

I'll report back after I swap fusers.

I swapped out the fuser from the good machine and that solved the problem, good call, working great. I put the suspect fuser in the high mileage machine and now it has the same symptom. I discovered that the other machine had a Jetdirect NT card. Can this be used to put the printer on a wireless nework?

Thanks for the great info.

Good work! NO the NIC is for a wired network. You could plug the printer into your router if you have one. If you have two or more computers in the house you can share that printer with the other computers. Some 2200's have an infrared port, not sure if the 2100's do?

So If I understand....I have a wireless router/access point. I could wire the 2100 into that and then all the computers on the network would see the printer and be able to use it? My 2100 does have the infrared port.

Thanks again.
