11-273 Mail Box OCT Offset Fail RAP
The Control Logic determined that either the Offset Home Sensor or the Offset Position Sensor
did not detect the OCT position within 600msec. for three consecutive attempts.
Initial Actions
• Refer to BSD11.7 for the following procedure.
• Ensure that connectors P/J564 on the Mail Box Control PWB, Shorting Plug P/J801A ,
Double Plug J880 , P/J803 on the Offset Motor, P/J806 on the Offset Position Sensor,
and P/J806 on the Offset Home Sensor are seated correctly and there are no obvious
crimped or broken wires.
Procedure
Manually move the Offset Catch Tray to the front/home position. Enter dC330 011-273 Offset
Home Sensor . The display indicates H.
Y N
Remove the Offset Catch Tray from the machine. leave the Offset Catch Tray electrically
connected. Open the Offset Catch Tray to expose the motor and sensors.
Enter
dC330 011-273 Offset Home Sensor . Press Start . Block the Offset Home sensor
with a sheet of paper. The display indicates H.
Y N
+5 VDC is measured between
P/J564 -7 on the Mail Box Control PWB and GND
Y N
Go to Flag 3 on BSD 11.7. Check the wire for a short circuit to ground. If the
wire is good, replace the Offset Home Sensor ( PL 14.1 ).
Replace the Mail Box Control PWB ( PL 13.10 ).
Ensure that the sensor actuator is properly installed, and not bent or distorted. If the prob-
lem continues, replace the Offset Home Sensor (
PL 14.1 ).
Manually move the Offset Catch Tray to the rear/offset position. The display changes to L.
Y N
+5 VDC is measured between
P/J564 -7 and GND.
Y N
Replace the Mail Box Control PWB (PL 13.10).
Disconnect P/J564 form the Mail Box Control PWB. +5 VDC is measured between P/
J564 -4 and GND.
Y N
Replace the Mail Box Control PWB ( PL 13.10 ).
Go to Flag 2, Flag 3 , and Flag 5 on BSD 11.7. Check the wires for an open circuit. If the
wires are good, replace the Offset Home Sensor ( PL 14.1 ).
Enter dC330 011-274 Offset Position Sensor . The display indicates H.
Y N
Remove the Offset Catch Tray from the machine. leave the Offset Catch Tray electrically
connected. Open the Offset Catch Tray to expose the motor and sensors.
Enter dC330 011-274 Offset Position Sensor . Press Start . Block the Offset Home sen-
sor with a sheet of paper. The display indicates H.
Y N
+5 VDC is measured between
P/J564 -6 on the Mail Box Control PWB and GND
Y N
Go to Flag 4 on BSD 11.7. Check the wire for a short circuit to ground. If the
wire is good, replace the Offset Position Sensor ( PL 14.1 ).
Replace the Mail Box Control PWB ( PL 13.10 ).
Ensure that the sensor actuator is properly installed, and not bent or distorted. If the prob-
lem continues, replace the Offset Position Sensor (
PL 14.1 ).
Manually move the Offset Catch Tray to the front/home position. The display changes to L.
Y N
+5 VDC is measured between
P/J564 -6 and GND.
Y N
Replace the Mail Box Control PWB ( PL 13.10 ).
Disconnect P/J564 from the Mail Box Control PWB. +5 VDC is measured between P/
J564 -4 and GND.
Y N
Replace the Mail Box Control PWB ( PL 13.10
).
Go to Flag 2 , Flag 4 on BSD 11.7, and Flag 5 on BSD 11.7. Check the wires for an open
circuit. If the wires are good, replace the Offset Position Sensor ( PL 14.1 ).
Enter dC330 011-095 OCT Offset Motor Rear On . Press Start . The Offset Catch Tray
moves to the rear/offset position.
Y
N
Press Stop . Less than +1 VDC is measured between P/J564 -1 and P/J564 -2
Y N
Replace the Mail Box Control PWB ( PL 13.10 ).
Enter dC330 011-095 OCT Offset Motor Rear On . Press Start . +24 VDC is measured
between P/J564 -1 and P/J564 -2
Y N
Disconnect P/J564
from the Mail Box Control PWB. Press Stop. Press Start. +24
VDC is measured between P/J564 -1 and P/J564 -2
Y N
Replace the Mail Box Control PWB ( PL 13.10
).
Go to Flag 2 on BSD 11.7. Check the wires for a short circuit to ground. If the wires
are good, replace the Offset Motor ( PL 14.1 ).
Go to Flag 2 on BSD 11.7. Check the wires for an open circuit. If the wires are good,
replace the Offset Motor ( PL 14.1 ).
Enter dC330 011-093 OCT Offset Motor Front On . Press Start . The Offset Catch Tray
moves to the front/home position.
Y
N
Replace the Mail Box Control PWB ( PL 13.10 ).
