HPLJ 4 Jams All The Time

[herring367]

Hi. My HP LJ 4 jams all the time. The paper start to come out and then it stops, and of course the jam light comes on. Every once in awhile I can get a test page to print completely.

What are some things I can check? Can the rollers be cleaned or adjusted? I don't mind pulling the printer apart since I'm going to toss it if I can't fix it.

Thanks!

It sounds like the output rollers are slipping. Those are the rollers located right at the exit. Typically when they slip, the trailing edge of the paper gets crumpled because the output rollers arent't pulling the paper through and the rollers at the bottom are still pushing the paper.

I don't believe a new set is very expensive. I have had some success in applying a thin coat of automotive brake fluid to the output rollers. Not too much. It make take a few sheets to get rid of surplus fluid.

The rollers are RF5-1076 AND RF5-1077...cheap & easily replaced.
