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 machine 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 (
p.4-60 "Paper Input and
Duplex Sensor Assembly
Removal").
Check the belt and drive of the
duplex unit. Replace it if necessary.
