4.2 Document Feeder Jam

1. Verify the original documents conform to the specifications designed for use in the machine and that
they are not damaged in any way.
2. Verify the number of documents placed into the feeder does not exceed its maximum capacity.

cloth moistened with a cleaning solution designed for use on rubber rollers. Replace the rollers if worn
or damaged.
6. Check the operation of DS1 at connector P122, pin 3-5, on the PCB connect ADF.
7. Check the operation of the separator roller, and the pick-up roller.
8. Verify the operation to the ADF Motor at connector P121, pins 1-6 on the PCB connect ADF.
9. Verify that the document feeds into the unit and stops. If the document does not stop, check the
operation of DS2 at connector P123, pin 1-3, on the PCB connect ADF.
10. Check all connectors and cables.
11. Check the operation of the main control board.
