I ahve a printer problem with the third tray of a Phaser 8560MFP. After printing from the 3rd tray (legal side letter), it gets jammed. After removing the jammed paper (completely intact with no torn), the error message didn't go away like it normally does. It still displays this message on the front display "Jam at front cover, lift the front cover to clear". Checked all the point and there aren't any paper anywhere. Even used a card board to slide thru the wheel to make sure no debris were left behind. Removed all the trays, checked the control panel area and turn on and off the machine but the error message is still displayed. At this point, with the error display, the printer is completely useless.
Any pointers on why the error message does not clear?
If you are 100% certain there is nothing in the printer to trip the sensor, and don't mind losing everything set on the printer, you can do an NVRAM Reset (Factory reset).
Hold down UP and then push OK
select Reset NVRAM > OK
If the above steps fail, the same can be found via System > Information > OK > Troubleshooting > OK > Service Tools > OK > Reset NVRAM > OK
If that fails to clear the message there is something in it tripping a sensor, try compressed air.
Would depend entirely on the fault codes.
Xerox does not supply service manuals, but if you were to Google "xerox 8560 service manual", I'm sure you cxould get this sorted out ;-)
I found the service manual and retrieved the error code:
after one hour, the paper path status test finished and here are the results:
