11-146 Decurler Exit Sensor On Jam Short RAP
The Decurler Exit Sensor did not detect the lead edge of the paper within the specified time
after the MC Exit Sensor detected the lead edge of the same paper.
NOTE: If this machine has a Finisher/Sorter Accessory, go to Section 8D, 11-146 Decurler Exit
Sensor On Jam Short RAP to troubleshoot this Fault Code.
Initial Actions
Refer toBSD11.1, BSD11.2 BSD11.3 and BSD11.4 for the following procedure.
Check for the following:
•
Obstructions in the Decurler paper path
• Bent or out of position paper chutes/guides in the Decurler paper path
• Ensure that there is sufficient nip force at the MC Exit Roll and the Decurler Entrance Roll.
• Ensure that connectors P/J654 , P/J653 , and P/J651 on the Decurler Control PWB, Dou-
ble Plug J571 , P/J570 on the Mail Box Control PWB and P/J658 on the Decurler Exit
Sensor are seated correctly and there are no obvious crimped or broken wires.
