hp laserjet pro 400 color show tray 1 paper jam issue

[kkkchuhk]

When I try to print it goes through the motions, I can hear things turning, but then it stops and says "Jam in tray 1." The feed roller doesn't turn. The tray does not lift. I can clear the error by removing tray 2 and opening/closing the back door. Opening the back door with the cassette still installed does nothing.

If I start over, remove all the paper from tray 2 and put paper in tray 1, and then try to print it says "Insert or close tray 2." Tray 2 is installed, and adding paper to tray 2 does nothing. Opening and closing the back door causes it to immediately show the "Jam in tray 1" error again, even if I already canceled the job.

Hello!

Please take out the carton and consumables and check whether there is paper jam or foreign matter inside the printer.

Restart the printer to confirm that the printer can return to the ready state.

If the printer is not ready, repair is recommended.

If the printer is ready, clean the paper take-up wheel of carton 1 and retest printing with normal A4 paper.

If the printer still has a paper jam problem, repair is recommended.

Sorry for the inconvenience.
