The Stacker Tray could not be lowered to the correct height, relative to the ejected sheets,
within 250msec during the height adjustment operation.
Initial Actions
Refer to BSD 12.15 for the following procedure.
Check that the actuator for the Stack Height Sensor is free to move.
Procedure
Enter dC330 012-250 Stack Height Sensor. Press Start. The display is High.
YN
Remove the Compiler Cover (R
EP 15.2.
22). Check that the Actuator is positioned cor-
rectly, and is blocking the sensor.
If the actuator is functioning correctly, Disconnect P/
J1073. Th
e display changes to
High.
YN
Go to Fl
ag 2 on BS
D 12.15. Check for a short circuit to GND. If the wire is good,
replace the Finisher PWB (PL 18.4).
Replace the Stack Height Sensor (PL 18.20).
Raise th
e Actuator. The display changes to Low.
YN
Disconnect P/
J10
73. There is +5 VDC from J1073-1 to J1073-3.
YN
+5 VDC is measured from P/
J1039-10 to
P/J1039-8.
YN
+5 VDC is measured from P/
J1026-3 to P/
J1026-2.
YN
Go to F
lag 17 on BS
D 12.1. Check the +5VDC wiring for an open circuit.
Replace the Finisher PWB (PL 18.4).
Go to Flag 1 on BSD
12.15. Check the harness for an open circuit.
There is +5 VDC from J1073-2 to J1073-3.
YN
Go to Flag 2 on BS
D 12.15. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB (PL 18.4)
Replace the Stack Height Sensor (PL 18.20).
If the problem continues, replace the Fin-
isher PWB (PL 18
.4).
Go to Flag 1 and F
lag 2 on BSD 12.15. Check for loose connections or an intermittent short cir-
cuit to GND. If the problem continues, replace the Stack Height Sensor (PL 1
8.20).
12-306 RAP
The Stapler Door Interlock Switch detects the Stapler Door open.
Initial Actions
Refer to BSD 12.3 for the following procedure.
Ensure that the Stapler Door is closed. Check f
or damage to the actuator, or an incorrectly
installed door. If the fault remains when the door is closed, continue with this RAP.
Procedure
Close the Stapler Door. Enter dC330 012-304 Staple Door INTLK Switch. Press Start. The
display is Low.
YN
Open the Stapler Door. Use the Interlock Cheater to actuate the Interlock Switch. The
di
spl
ay is Low.
YN
There is +5 VDC from P/
J1033-3 to
GND.
YN
Replace the Finisher PWB (PL 18.
4).
Go to Flag 3 and F
lag 4 on BSD 12.3. Check for an open circuit. If the wires are
good, replace the Stapler Door Interlock Switch (PL 18.11).
Check the Stapler Door (PL 18.2) f
or damage.
Open the Stapler Door. The display is High.
YN
There is less than 1 VDC from P
/J1033-
5 to GND.
YN
Replace the Finisher PWB (PL 18.
4).
Go to Flag 3 and Fl
ag 4 on BSD 12.3. Check for a short circuit. If the wires are good,
replace the Stapler Door Interlock Switch (PL 18.11)
The problem may be intermittent. Check the Stapler Door for warping or damage. Ensure that
the
actuator lines up with the switch.
Go to Fl
ag 3 and F
lag 4 on BSD 12.3. Check for loose connections or an intermittent short cir-
cuit to GND. If the wires are good, replace t
he Stapler Door Interlock Switch (PL 18.11)
