The Eject Clamp Sensor does not detect the Eject Clamp in the closed position within
500msec from the start of Eject Roll Down.
Initial Actions
Refer to BSD 12.1 and BSD 12.14 for the following procedure.
Procedure
Enter dC330 012-026 Eject Clamp/Offset Motor Up/Down. Press Start. The

Y N
Switch off the power. Remove the rear covers. Manually rotate the shaft of the Eject
Clamp/Offset Motor (PL 18.21) counterclockwise. The shaft moves freely.
Y N
Disassemble the gear cluster
Manually rotate the motor shaft The shaft moves freely.
Y N
Replace the Eject Clamp/Offset Motor
Check the following:
• Check the gears for damage or dirt that may cause binding
• Check the Eject Roll
• Check the Pinch Roll/Compiler Cover/Set Separator area for binding
