5. Ensure that the drum maintenance tray is fully installed by pushing
firmly.
6. Check that the pick roller is being rotated. If it is not, go to the topic
"Checking the process motor and drive train" on page 6-13.
Otherwise, go to Step 5. In its starting position, the pick roller's flat
side should face down; the flat, keyed end on the left end of the pick
roller shaft faces up.
7. Clean the pick roller. Paper dust can coat the pick roller and affect its
ability to grip the paper and pull it out of the tray. Also clean the
transport rollers.
8.
Refer to the later topic "PC-based diagnostics" on page 6-29. Use the
Sensors/Actuators and Paper Path tests to check the operation of the
paper pick system.
9. Inspect the wiring harness leading to the paper transport clutch for
nicks, cuts or crimped wiring. Ensure the connector is seated.

1. Test the paper preheater sensors. Refer to the later topic, "PC-based
diagnostics" on page 6-29. If the sensor fails the test, replace the paper
pre-heater.

of its pulleys. In such a case, the upper roller does not rotate when the
lower roller rotates.
3. Inspect the idler rollers on the inside of the top-front cabinet panel;
they should rotate freely.
4. Check that the feed rollers rotate smoothly and that the front cover is
fully closed and seated.
5.
Check the paper-eject path for obstructions. Test the sensors i the
paper path.
6. Ensure that the transfer roller rotates during the transfix process.
