Steps Actions and Questions Yes No
1 Check the stack full actuator:
1.Open the paper exit assembly cover.
2.Manually operate the stack full actuator.

smoothly?
Does the flag move between the sensor
arms when there is no paper, and out of
the sensor arms when paper is present?
Go to step 2. Replace the
stack full
actuator
(“Output Tray

on
page 8-52).
2 Check the output tray full sensor (1):
1.Enter Service Diagnostics, and from the
Sensor Tests menu select Output
Tray Full Sensor.
2.Manually raise and lower the stack full
actuator.
