Status Indicator RAPs Initial issue
12-281 Set Clamp
The Set Clamp Home Sensor does not actuate after the Set Clamp started operation.
Procedure
Remove the Rear Cover ( PL 17.5 ). Enter dC330 [012-211] and press Start . Actuate the Set
Clamp Home Sensor ( PL 17.8 ) ( Figure 1 ). The display changes.
Y N
Press Stop . Check the circuit of the Set Clamp Home Sensor ( Figure 2 ). Refer to the OF
99-2 RAP for troubleshooting procedure.
Press Stop . Enter dC330 [012-040] and press Start . The Set Clamp Solenoid ( PL 17.8 )
energized.
Y
N
Press Stop . Check the circuit of the Set Clamp Solenoid ( Figure 3 ). Refer to the OF 99-4
RAP for troubleshooting procedure.
Press Stop . Enter dC330 [012-034] and press Start to energize Eject Clamp up and then [12-
032] and press Start to lower the Eject Clamp. Enter dC330 [012-041] and press Start . The
Set Clamp ( PL 17.12 ) rotated.
Y N
Enter dC330 [012-030] and press Start . The Eject Motor ( PL 17.8 ) energized.
Y N
Remove the Rear Cover ( PL 17.5 ). +24 VDC is measured between P/J881 - 2 and
5 on the Eject Motor and GND ( Figure 4 ).
Y N
+24 VDC is measured between
P/J846 - 6 and 12 on the Finisher PWB and
GND.
Y
N
Replace the Finisher PWB ( PL 17.13 ).
Check wiring between P/J846- 6 and 12 and P/J881- 2 and 5 for damage or
poor contact.
+24 VDC is measured between P/J881- 1, 3, 4 and 6 on the Eject Motor and
GND.
Y
N
Replace the Eject Motor ( PL 17.8 ).
Check the wires from P/J846 to P/J881 for damage or poor contact. If the check is
OK, replace the Finisher PWB ( PL 17.13 ).
Check the following:
•
Eject Roll for wear and a drive failure ( PL 17.8 ).
• Eject Shaft for wear and a drive failure ( PL 17.8 ).
• Each Driver Gear for wear, a drive failure, and breakage ( PL 17.8 ).
• Belt for disengagement, breakage, and improper tension ( PL 17.8 ).
Press Stop .
• 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 Set Clamp Home Sensor ( PL 17.8 ).
• If the problem persists, replace the Finisher PWB ( PL 17.13 ) ( Figure 5 ).
