HP LaserJet 4 - 41.3 error

I am getting 41.3 errors.

This printer is over 10 years old. Not used much. Error-free until now.

Can this be fixed reliably or should I just get a new printer?
Unexpected paper size. Make sure the printer knows what size paper is going through.

Checking the print properties - it is set to Letter size.

Are you getting this error out of the manual tray 1 or tray 2?

If I print pages individually, there is not a problem.

If I select to print a multi-page document, I get the 41.3 error around the 3rd page.

If you are printing out of tray 1, it may be time for you to replace the pickup roller and the separation pad.

If you go to the bottom and type lj 4 in the search. It will take you to another page. Look to the right for repair kit.

Actually, all you have to do is scroll to the top of the page. The 41.3 error in the subject line automatically creates a link at the top of the page. - moe
Basically the 41.3 error occurs when the paper reaches ps1 sensor which is the registration sensor is activated by paper before the dc controller expects that to happen. Usually it is because of 2 sheets feeding where it grabs one sheet and then about 1/3 of the way in another sheet starts. In other words it is a misfeed issue. If you are drawing from tray 1 (manual feeder), then yes the separation pad is probably worn. If drawing from the cassette tray, the paper holder on the left side may have become bent. Another issue which can lead to this happening is one of the selenoids on the paper input assembly having an issue with glue residue. HP used to use a velcro like material on the L shaped arm which locked the pickup gear until the paper cyele starts when the selenoid forces the L shaped arm towards the center and releases the gear. The power is turned off to the selenoid and the arm returns with spring action and locks the gear until the next time. To keep the noise of the L shaped arm down, HP used a velcro like material which was glued to the arm to muffle the sound. Over time the material will start to disintigrate and all that was left was the glue which held it. What would happen is when the L arm was pulled towards the center it would stick to the selenoid even after the power was off and eventually return but not when it was suposed to. If the arm stick, the printer immediatly picks up another sheet of paper and it reaches ps1 to fast and hence the 41.3 error. If this is your problem you can fix it, but you will have to remove the PIU (not that hard), clean off the L arm and then put a piece of electrical tape over it.
