Diagnostics information 2-13
231.00 Duplex jam while reversing into the device Open the rear cover and look for obstructions
between the rear cover ribs, the fuser exit rollers,
and below. The media entering the duplex passes
outside the exit roller while the media exiting the
fuser passes above and inside the exit rollers.
Remove the tray, open the duplex door, and remove
the obstructions. If there are no obstructions and the
problem persists, then disconnect all of the cables,
tilt the printer onto its back (be sure to protect the
antenna on a wireless unit), and inspect the flag of
the duplex sensor. If the flag does not rotate freely,
then replace the paper input and duplex sensor. See
“Paper input and duplex sensor assembly
removal” on page 4-44.
Check the belt and drive of the duplex unit. Replace
it if necessary.
