10-133 Duplex Out Sensor On Jam RAP

The Duplex Out Sensor did not actuate within the specified time after the start of Reverse
Feed.
Initial Actions
Refer to BSD 10.8, 10.9, and 10.12 for the following procedure.
Check for the following:
Proper Nip Drive force at Drive Rolls (Baffle latches properly).
Obstructions in the paper path.
Contamination on the Duplex Path Roll
Ensure that connectors P/J412A, P/J417A, and
Drive PWB and there are no obvious crimped or broken wires.
Procedure
Enter dC330 010-133 Duplex Out Sensor. Ensure the Drawer is closed. Press Start. The
display indicates L.

NOTE: To block the Duplex Out Sensor, open the Drawer then open Jam Clearance Lever 3
on the bottom of the Drawer. Place a sheet of paper on the baffle, close the baffle and Drawer.
