HP 4100 tn paper tray 2

When I open my papertray and then close it, my HP 4100 gives the message: "paper tray 2 empty, please load". Problem is: the tray is never empty. I have to push all paper several times to the front and then (if I'm lucky) the printer starts to print.

Is there something wrong with the papertraysensor and if so: how can I fix this?

Are you receiving the message after the machine cycles and tries to pull paper from the tray. If this is the case replace the paper feed roller in the machine. Located in the front of the paper cavity in the top,front,center. You may also want to replace the roller on the front of the paper tray.

If you're needing to push the paper to the front, then it would seem the back stop is not latching in place. Replacement back stops are available. You can also tape it in place as a temporary fix and if you don't need to move it to adjust for different paper sizes.

(In respons to aerolaser) No, the machine doesn't cycle or try anything. He gives this message instantly. And I have replaced the paper feed roller some time ago. IF the machine "sees" that there is paper in the tray, it always works out fine. So that doesn't seem to be the problem.

(In respons to moe) Yes, I have to push the paper (and also the back stop) to the front, but only 1 or 2 millimeter (just a little bit). The back stop remains in place, but it looks like the machine doesn't "see" the paper and I have to put it in front of a sensor or someting, I don't know.

Is there some papersensor in the HP4100?

Print a config page to see what the printer thinks that tray 2 has in it. Config page is in the Information Menu. Tell us what that says and what size paper you really have in the tray.
