0 HP LaserJet 4 HP LaserJet 4 HP Laserjet 5L Error light will not go away! I purchased the feeder roller repair kit and installed it. I also checked to make sure the cables were securely fastened. I also checked the registration sensor and the pivoting sensor in the front of the machine. According to the CD video guy, both of my sensors are responding correctly (or at least look like they are). I followed the instructions in my manual to fix the problem.

1) Add paper

2) Close the door

3) Reinstall the cartridge

4) Check for paper jam

5) Reset the printer by using the front button

6) Disconnect the power

7) Use expletives and cry a lot

With paper in the tray, when I open and close the door the printer makes noise (probably the rollers rotating) for a couple of seconds and then stops. All of the cable connections are fine and I changed out the data cable just to try to chase down the problem. Unfortunately the problem is internal to the printer, so the data cable idea is mute. If only I could run a test print…



Do you have any ideas how I can rectify the problem?

0 Are all the lights on or just the error light? If all the lights are on hold the front button down to show the true error. by unknown on Mar 21, 2002 at 6:49pm

0 Thanks for asking Will, only the top (amber) light is on. Any Ideas? by unknown on Mar 24, 2002 at 8:09am

0 Assuming the light wasn't on before you did the repair, that would mean that it was a fault you put in during the repair. The most likely cause would be the connector at the back of the Pickup Assy. The one with the blue wires going to it. The sensors run through that connector. Either it isn't seated firmly enough or you might have bent a pin installing it. by moe on Mar 24, 2002 at 1:34pm

0 Thanks Moe,



I believe the light was present before I installed the new hardware. I was very careful not to damage the contacts or the pins during reassembly. I could disassemble the printer again (for the third time), but I do not want to compound the chances of damaging anything. Do you have any other suggestions as to what could be the error? If the error was present prior to the roller installation, where would you look? Is there any way I could hook up my meter to some contacts to chech for continuity? If so, which contacts and where do I place my meter contacts. Thanks for your help! by unknown on Mar 25, 2002 at 5:25pm

0 I'd check out the interlock switch on top of the printer. I've seen them break. You can manually trip the switches and simulate the door being closed and see if the light goes away. Make sure the cartridge is installed and paper is in the tray. You'll have to remove the covers of course. by moe on Mar 25, 2002 at 10:23pm

0 Well Moe, you may have called this one. I did as you instructed, remove the cover, put paper in the tray and trip the upper switch. I still have an amber error light. Maybe that is the problem. I will attemp to find a replacement switch locally. Unfortunately, they mushroomed the end of the post so the switch would not come off. Of course I broke the post off trying to remove the switch. I'll have to find a self tapping screw small enough to pass through the mounting hole. Do you have any suggestions? And by the way, thanks for your input! by unknown on Mar 29, 2002 at 4:12pm
