14-372 ROS Motor Fail RAP
The SOS Sensor did not go Low within a specified time after the Polygon Motor energized.
Initial Actions
•
Refer to BSD 6.5, BSD 6.6, and BSD 6.7 in the following procedure.
•
Verify that the Drum Unit is firmly seated and that the screws that hold the unit in place
are installed.
•
Verify that
P/J420A
on the lOT Drive PWB, and
PWB are firmly connected.
Procedure
Open the Front Door and cheat the Interlock. Enter dC330 014-050 Polygon Motor Low Speed.
Press Start. When the Polygon Motor rotates you can feel vibrations by placing your hand on
the Drum Module Cover. The Polygon Motor is rotating.
