YN
+5 VDC is measured between P/J
651-3 and P/J651-4 on the Finisher PWB.
YN
+5 VDC is measured between P
/J1028
-3 and P/J1028-4 on the Finisher
PWB.
YN
+5 VDC is measured between P/J
880
-3 and P/J880-2.
YN
Go to the +5VDC F
igure 1
wirenets and check wires for an open or
short circuit.
Go to Flag 17 on BS
D12.1 and check the harness for an open circuit.
Replace the Finisher PWB (PL 18.4).
Replace the Decurler Exit Sensor (PL 18.6).
Go to Fl
ag 9 on BS
D12.6. Check the wire for an open circuit. If the wires are good,
replace the Decurler Exit Sensor (PL 18.6).
More than +4.5 VDC is measured between P/J658-2 and
GND on the Decurler Exit Sen-
sor.
YN
Replace the Decurler Exit Sensor (PL 18.6).

11-146 Decurler Exit Sensor On Jam Short RAP
The Decurler Exit Sensor did not detect the lead edge of the paper within the specified time
after the MC 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/J651 on the Decurler PWB, Double Plug
P/J661, P/J1028 on the Finisher PWB and P/J658 on the Decurler Exit Sensor are
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.
YN
The paper entered the Decurler.
YN
The Entrance Rolls are rotating when the Jam occurs
YN
Enter dC330 012-010 Decurler Stepping Motor Speed 60. The Decurler Step-
ping Motor rotates.
YN
Check F1 fuse on the Decurler PWB. The fuse is open (blown).
YN
+24 VDC is measured between P
/J653
-1 and GND on the
Decurler PWB.
YN
+24 VDC is Measured between P/
J1026-
1 and GND on the
Finisher PWB.
YN
Replace the Finisher PWB (PL 18.
4).
G
o to Wire Net +24VDC-2. Check the wire for an open circuit. If
the
wire is good, replace the Decurler PWB (PL 18.6).
Press Stop. +24 V
DC is measured between P/J653-3, 4, 5, 6 and
GND on the Decurler PWB.
YN
Replace the Decurler Motor (PL 18.
8).
If the problem continues,
replace the Decurler PWB (PL 18.6).
Press Start. app
roximately +1.5 VDC is measured between P/
J653-3, 4, 5, 6 and GND on the Decurler Control PWB.
