Remove the tray and turn it upside down.
The tray guides are connected at the center
of the tray by a toothed gear that ensures
they move in unison. If not, remove the
screw at the center of the gear and, using a
sheet of paper in the tray as a template,
realign the guides.
Reseat the roller at the leading edge of the
transfer belt.
Make sure the correct amount of paper is in
the tray and that it is under the corner
bucklers.
The paper lift tray must be pushed down to
the lock position every time the drawer is
closed.
Check to ensure that the paper size
adjustment is correct for the paper being
used. Ensure that the paper size sensor
actuators are not bent or broken. Make sure
that there are no broken parts on the
cassette that would allow the cassette to
move or shift from it's intended position
inside the printer.
Be sure that connector CN2 on the printer
controller board is connected properly. Also
check CN4 on the expansion paper feeder
control board for the associated tray.
