Symptom

Unusual clattering noise is heard when a duplex job starts and the system starts to feed paper. Jam074 occurs, followed by Jam097, which occurs 3 times in succession. The system finally stops with an SC516-02 (sensor shift motor edge detection error).

Cause

The paper size (A4 or 81/2) fixed with the end fence on the tandem tray does not match with the size specified on the control panel.

The shift roller in the duplex unit operates according to the paper size specified on the control panel, resulting in the above jams and SC.

Solution
  1. Check the paper size fixed with the end fence on the tandem tray.
    Photo below describes an example of the end fence fixed to A4 size.
  2. Check the paper size specified for the tandem tray on the control panel.
  3. If the sizes do not match, enter SP5-959-001; Paper Size: 1st Tray (Tandem) and specify the size according to the paper in use.
    0: A4 LEF
    1: 81/2 × 11 LEF
  4. Turn the main power off/on.
  5. Confirm proper duplex printing to complete the procedure.
