10-112 Machine Exit Sensor On RAP
The Machine Exit Sensor detected paper when closing the Front Cover or when power was
switched on.
Initial Actions
Refer to BSD 10.7 and 10.12 for the following procedure.
Check for the following:
•
Obstructions in the paper path.
•
Ensure there is no paper on the Machine Exit Sensor.
•
Ensure that connectors

•
Ensure the Inverter is closed. Switch the power Off then On.

The Exit Path Sensor did not actuate within the specified time after the Fuser Exit Sensor actu-
ated.
Initial Actions
Refer to BSD 10.7, 10.4, and 10.12 for the following procedure.
Check for the following:
•
Obstructions in the paper path or damage on lead edge of sheets
•
Contamination on the Fuser Exit Roll.
•
Cheat the Front Door Interlock and observe the paper as it feeds out of the Fuser Exit
Assembly and into the Inverter Top Chute Assembly. Ensure that the lead edge is not
catching on the Inverter 1 Baffle or Inverter Gate. Also, check the function and position of
the Inverter gate and Inverter Gate Solenoid dC330 010-005 Inverter Gate Solenoid (Exit)
and 010-006 Inverter Gate Solenoid (Invert).
