6.5.1 Tests and Wiring Diagram
The following tests and the Figure 6–14 wiring diagram can be used to
troubleshoot to components beyond the FRU level:
• Enter 0400.01 to run the drive gears. Look for jerky motion caused by
missing teeth or gear damage and listen for thumps or grinding noises.
• Enter 0810 and manually actuate the registration sensor. If the test fails,
swap the registration sensor and DC control board.
• Test the upper turn and registration roller clutches for slippage. Test the
clutch by manually rotating the roller. The roller must turn freely when
the clutch is deactivated and must lock up when the clutch is energized.
– Enter 0851 for the upper turn roller clutch (shown in Figure 6–4).
– Enter 0805 for the registration roller clutch.
