10-280 OCT Offset Sensor Failure RAP, 10-300 In-
Status Indicator RAPs
Reissue
Connect the meter from P/J422A -9 on the IOT PWB to GND. Manually move the Stacker
Tray toward the rear until it stops, and then toward the front, until it stops. The voltage at
P/J422A -9 goes from than +5.0 VDC when the tray is to the front, to less than +1.0
VDC when the tray is moved off the front position.

Go to Flag 1 and Flag 2 on BSD 10.11 and check the harness for an open circuit. If
the harness is good, replace the OCT Offset Home Sensor ( PL 14.1 ).
Replace the IOT Drive PWB ( PL 9.2 ).
Enter dC330 010-299 OCT Position Sensor . Press Start . Enter dC330 010-086 Offset Motor
Forward . Press Start . Enter dC330 010-085 Offset Motor Reverse . Press Start . The dis-
play changes from L to H to L.

Go to Flag 3
on BSD 10.11 and check the harness for a short circuit. If the harness is
good, replace the OCT Offset Position Sensor ( PL 14.1 ).
Connect the meter from P/J422A -8 on the IOT PWB to GND. Manually move the Stacker
Tray toward the rear until it stops, and then toward the front, until it stops. The voltage at
P/J422A -8 goes from less than +1.0 VDC when the tray is to the front, to +5.0 VDC
when the tray is moved to the rear position.

Go to Flag 3 and Flag 4 on BSD 10.11 and check the harness for an open circuit. If
the harness is good, replace the OCT Offset Position Sensor ( PL 14.1 ).
Replace the IOT Drive PWB ( PL 9.2 ).
Check for obvious damage, missing and/or broken Offset Motor gear assemblies.
10-300 Inverter Cover Open RAP
The Inverter Cover is detected open.
Initial Actions
Refer to BSD 10.8 and 10.12 for the following procedure.
Check for the following:
•
Open and close the Inverter Cover. While physically pushing on the Inverter Cover, switch
the power off then on. If the Fault Code does not appear, check Inverter Cover latch and
alignment for damaged parts.
• Ensure that connectors P/J412A and P/J152 are seated correctly on the IOT Drive PWB,
and the Inverter Cover Switch and there are no obvious crimped or broken wires.
Procedure
Enter dC330 010-300 Inverter Cover Interlock . Open the Inverter Cover. Manually actuate the
Inverter Cover Switch. The display changes from H to L when the switch is actuated.
Y N
Connect the meter from P/J412A -11 on the IOT Drive PWB to GND. Manually actuate the
Inverter Cover Switch. The voltage at P/J412A -11 goes from +5 VDC to less than +1.0
VDC when the switch is manually actuated.
Y
N
Go to Flag 3 on BSD 10.8. Check the harness for an open circuit. If the harness is
good, replace the Inverter Cover Switch ( PL 2.24 ).
Replace the IOT Drive PWB ( PL 9.2 ).
If the fault code is present and can not be cleared, replace the IOT Drive PWB ( PL 9.2 ). If the
fault code is not present and is occurring intermittently, go to Flag 3 on BSD 10.8 and check the
harness for an intermittent open circuit. If the harness is OK, replace the Inverter Cover Switch
(
PL 2.24 ). If the problem continues, replace the IOT Drive PWB ( PL 9.2 ).
