Initial issue
12-267 Decurler
The Decurler Cam Home Sensor did not actuate after the Decurler Cam Clutch energized.
Procedure
Remove the Rear Cover (PL 17.5). Enter dC330 [012-217] and press Start. Actuate the
Decurler Cam Home Sensor (PL 17.8) (Figure 1). The display changes.
YN
Press Stop. Check the circuit of the Decurler Cam Home Sensor (Figure 2). Refer to the
OF 99-2 RAP for troubleshooting procedure.
Press Stop. Enter dC330 [012-070] and press Start. The Decurler Cam Clutch (PL 17.7)
energized.
YN
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.
YN
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.
Remove the other mechanical causes of the Decurler Cam not operating.
Press Stop. Enter dC330 [012-001] and press Start. The Finisher Drive Motor (PL 17.7)
energizes.
YN
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).
YN
+24 VDC is measured between P/J846 -5 and 7 on the Finisher PWB and GND.
YN
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.
YN
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,
replace the Finisher PWB (PL 17.13).
• Ensure that the connectors shown in the circuit diagrams (Figure 2, Figure 3, Figure 4)
are securely connected and that the wires are not damaged.
• Replace the Decurler Cam Home Sensor (PL 17.8).
• If the problem persists, replace the Finisher PWB (PL 17.13) (Figure 5).
