Hello Folks,
My trusty old LaserJet 4 has, all of a sudden, started getting paper jams. The jams are 100% consistent, paper jams every time and in exactly the same place. The sheets get about 3/4 of the way out of the fuser and just reach the output assembly rollers and then stop. I have also tried various paper types and my usual brand is HP Laser Paper (so that ought to be OK!).
There are no paper fragments in the path. I have removed the fuser unit and there are no broken gears and the mechanism seems to be functioning normally. The output assembly also seems to be functioning correctly (and it never creates an "accordian" fold). I have tried paper both from the cassette tray and the manual feed tray and the outcome is the same.
My guess - there is a malfunctioning sensor somewhere but I don't know where.
Ideas anyone?
