HP LaserJet 4P Paper Jams - strange problem

Archived from groups: comp.periphs.printers (More info?)

Hi all

With my HP LaserJet 4P experience the following problem:

1. When job of few pages is processed from the tray, after few pages
are printed I get eventually "Paper jam" error. The actual reason
found by me is that there is overlapp (of ~1 inch) between previous
paper and the new one: The printer begin to load new paper too early,
before the previous paper left the path, and it prints the bottom of
the previous page on the head of the new paper, then stop on "Paper
jam".
2. When job is processes from manual feed, and I wait until I see the
previous paper begin to get out before I feed the new paper, there are
no problems.

Do someone experienced this problem? Have any idea how to locate/solve
the problem?

With best regards
