N
Press Stop . Check the circuit of the Decurler Cam Clutch ( Figure 3 ). Refer to the OF 99-4
RAP for troubleshooting procedure.
Press Stop . Enter dC330 [012-071] and press Start . The Decurler Cam ( PL 17.7 ) energizes.
Y N
Press Stop . Check the following:
• The Decurler Cam Clutch for slippage.
• The Driver Gear for wear, a drive failure, and breakage.
• The belt for disengagement, breakage, and improper tension.

N
Remove the Rear Cover ( PL 17.5 ). +24 VDC is measured between P/J879 -2 and 3 on
the Finisher Drive Motor and GND ( Figure 4 ).
Y N
+24 VDC is measured between
P/J846 -5 and 7 on the Finisher PWB and GND.
Y N
Replace the Finisher PWB ( PL 17.13 ).
Check the wiring from P/J846-5 and 7 to J879-2 and 3 for damage or poor contact.
Enter dC330 [012-001] and press Start . Less than +1 VDC is measured between P/
J879 -1 on the Finisher Drive Motor and GND.
Y
N
Replace the Finisher Drive Motor ( PL 17.7 ).
Check wiring between P/J879 and P/J846 for damage or poor contact. If the check is OK,
