The Stapler Rear Straight Sensor does not detect the presence of the Stapler within 1600
msec. after the Stapler Position Motor was energized to move the Stapler.
Initial Actions
Refer to BSD 12.12 for the following procedure.
Check the following:
• Obstructions in the Stapler Rail Assembly (PL 18.18) t
hat would prevent movement of the
Stapler
• Bent or out of position End Wall
• Bent or out of position Compiler Tray
• Clean the Stapler Rear Straight Sensor
• Ensure that connector P/J
1035 on the Finisher PWB and P/J1060 on the Stapler Rear
Straight Sensor and seated correctly and there are no obvious crimped or broken wires.
Procedure
Remove the Stapler Cover Assembly (REP 15.3.3). Manually move the Stapler to the rear of
the Finisher until it has cleared the Stapler Rear Straight Sensor and the sensor is not blocked.
Enter dC330 012-279 Stapler Rear Straight Sensor. Press Start. The display indicates
Lo
w.
YN
Go
to F
lag 1 and Fl
ag 5 on BSD 12.12. Check the wires for an open circuit or a short cir-
cuit to GND. If the wires are good, go to Flag 2
on BSD 12.12. Check the wire for an open
circuit. If the wire is good, replace the Stapler Rear Straight Sensor (PL 18.18). If the prob-
lem continues, replace the Finisher PWB.
Block the Stapler Rear Straight Sensor. The display changes to High.
YN
Go to F
lag 2 on BSD 12.12. Check the wire for a short circuit to GND. If the wire is good,
replace th
e Stapler Rear Straight Sensor (PL 18.18). If the problem continues, replace the
Finisher PWB (PL 18.4).
Perform the following:
• Manually move the Stapler toward the front and rear of the Finisher to ensure that it
mov
es s
moothly and that there are no obstructions in the Stapler travel. Correct any prob-
lems found.
• Replace the Stapler Rear Straight Sensor (PL 18.
18).
•
If the problem continues, replace the Finisher PWB (PL 18.4).
12-251 RAP
When either of the following occur:
• The Eject Paddle Home Sensor does not detect the Eject Paddle in the Home position
within 400mse
c of the signal, Eject Paddle Motor On.
• The Eject Paddle remains at the Home position 200msec after the signal, Eject Paddle
Motor O
n.
Initial Actions
Refer to BSD 12.1 and BSD 12.14 for the following procedure
Procedure
Enter dC330 012-053 Eject Paddle Motor. Press Start. The Eject Paddle rotates.
YN
Remove the Belt from the Eject Paddle Motor (PL 18.
19).
Enter dC330 012-053 Eject
Paddle Motor. Press Start. The Eject Paddle Motor rotates.
YN
Go to Fl
ag 12 and Fl
ag 13 on BSD 12.14. Check the wires for an open circuit. If the
wires are good, replace the Eject Paddle Motor (PL 18.19). If the problem continues,
replace the Finisher PWB (PL 18.4).
Check the Eject Roll (PL 18.
19)
for damage, binding or misalignment
NOTE: The output of the Eject Paddle Home Sensor is Low when the sensor is blocked
, and
High when the sensor is not blocked.
Enter dC330 012-241 Eject Paddle Home Sensor. Press Start.
Manually actuate the Eject
Paddle Home Sensor. The display changes from High to Low to High as the actuator
moves i
n and out of the sensor.
YN
The display is always Low.
YN
Disconnect P/
J1055. T
here is +5 VDC from J1055-1 to J1055-3.
YN
+5 VDC is measured from P
/J1037
-2 to P/J1037-3.
YN
+5 VDC is measured from P
/J1026
-3 to P/J1026-2.
YN
Go to F
lag 17 on BSD 12.1. Check the +5VDC wiring for an open cir-
cuit
.
Replace the Finisher PWB (PL 18.4).
Go
to Flag 5 on BS
D 12.14. Check the harness for an open circuit.
There is +5 VDC from J1055-2 to J1055-3.
YN
Go to Flag 6 on BS
D 12.14. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB (PL 18.4)
