A
• SCT Exit Roll (PL 18.10)
• Drive Belt (PL 18.10)
Check the Drive Belt Tension Roll for proper tension.
Enter dC330 012-142 Mailbox Entrance Sensor. Manually actuate the Mailbox Entrance Sen-
sor actuator. The display changes from L to H to L as the actuator moves in and out of
the sensor.
Y N
The display is always H
Y N
Go to Flag 8 on BSD12.7. Check the harness for a short circuit to ground. If the har-
ness is good, replace the Mailbox Entrance Sensor
+5 VDC is measured between P/J1040-2 and P/J1040-3
Y N
CR1 on the Mailbox PWB is on.
Y N
Go to the +5 VDC wirenet and troubleshoot the wires between P/J1040-4 and
P/J44-22 on the Distribution PWB.
Replace the Finisher PWB (PL 18.4).
Go to Flag 8 and Flag 7 on BSD12.7. Check the harness for an open circuit. If the har-
ness is good, replace the Mailbox Entrance Sensor
With paper at the sensor, less than +0.5 VDC is measured between P/J1040-4 and GND.
Y N
Replace the Mailbox Entrance Sensor
Check the following parts for wear, glazing, or slipping.
• Mailbox Entrance Roll (PL 18.10)
• Pinch Rollers (PL 18.12)
• SCT Exit Roll (PL 18.10)
• Drive Belt (PL 18.10)
Check the Drive Belt Tension Roll for proper tension.

11-145 Decurler Exit Sensor On Jam Long RAP

The Decurler Exit Sensor did not detect the lead edge of the paper within the specified time
after the M/C Exit Sensor detected the lead edge of the same paper.
Initial Actions
Refer toBSD12.1, BSD12.5, BSD 12.6 and BSD12.7 for the following procedure.
Check for the following:
• Obstructions in the Decurler paper path
• Bent or out of position paper chutes/guides in the Decurler paper path
• Ensure that there is sufficient nip force at the MC Exit Roll and the Decurler Entrance Roll.
• Ensure that connectors P/J654, P/J653, and
P/J661, P/J1028 on the Finisher PWB and
seated correctly and there are no obvious crimped or broken wires.
Procedure
The lead edge of the paper is at or past the Decurler Exit Sensor.
Y N
The paper entered the Decurler.
Y N
The Entrance Rolls are rotating when the Jam occurs
Y N
Enter dC330 012-010 Decurler Stepping Motor Speed 60. The Decurler Step-
ping Motor rotates.
Y N
Check F1 fuse on the Decurler PWB. The fuse is open (blown).
Y N
+24 VDC is measured between
Decurler PWB.
Y N
+24 VDC is measured between P/J1026-1 and GND on the
Finisher PWB.
Y N
Replace the Finisher PWB
Go to Wire Net +24VDC-2. Check the wire for an open circuit. If
the wire is good, replace the Decurler PWB
Press Stop. +24 VDC is measured between P/J653-3, 4, 5, 6 and
GND on the Decurler PWB.
Y N
Replace the Decurler Motor
replace the Decurler PWB
Press Start. approximately +1.5 VDC is measured between
J653-3, 4, 5, 6 and GND on the Decurler Control PWB.
Y N
Press Stop. +5 VDC is measured between P/J1026-3 and
GND
