11-350 Decurler 1 Fail RAP
This status code is declared when the Decurler Cam Position Sensor did not energize within
the specified time (1400msec) after the Decurler Cam Clutch is energized.
Initial Actions
• Refer to BSD12.6 for the following procedure.
• Ensure that connectors P/J652 , and P/J651 on the Decurler PWB, P/J1028 on the Fin-
isher PWB, and P/J656 on the Decurler Cam Sensor are seated correctly and there are
no obvious crimped or broken wires.
