Hp HP LaserJet 5MP

HP Laserjet 5MP

on powering up, this HP5MP a friend asked me to look at for him sits there with all the lec's lit, hitting the online button causes the leds to chase up the line twice from the online button to the formfeed button, then it settles on the paper jam led on solid.

This printer was working fine until the owner removed the fuser to remove some paper that was wrapped around the upper roller.

Any suggestions?

is there any way to get a meaningful disgnostic from this thing?
When you get all the lights on, you have to hit both buttons to get the secondary error code.

Ok, I found 1 loose connection inside so far, but it's still not working.
on powerup all LED's light and stay that way for ~ 60 seconds, then the leds go into thir chase sequence then it stops withthe error led lit.

it's not heating the fuser or anything like that... just coming up into an error condition

If the owner removed the fuser, he probably messed up the exit sensor somehow.

any suggestions on how to fix the exit sensor?

You could try to remove the fuser and re-sit it and see if that would help or not. If that doesn't fix it. You will need to remove the Fuser and the bottom metal place to check the linkage arm and the sensor which i son teh main board.

to remove the metal plate am I going to have to remove the printers logic board? it looks like it to me, there seem to be 2 small screws behind the logic board.

no. take the covers off (four screws and locking tabs). don't forget, slide the formatter cover off first. and the fuser comes out of the back via 4 screws, after you take the little black protective cover off. inspect the fuser, and it's jam flag, and seat it correctly. good luck

Chris, I've already done that twice, and it made no difference :( so i'm up to removing the metal plate and cheking the linkage arms and sensors.

You don't have to remove the logic board but you do have to remove the two little screws that help jold the plate from the side where the logic board is at. You have to use a longer screw driver for that job but should be able to do it.

The logic board and the fuser both have to come off as they plug into the controller board.
