Troubleshooting
Step Check
Check of connection of DRIVE ASSY PRO
1
(IBT Cleaner Retract Motor)
Is connector P/J414 connected firmly to
PWBA MCU?
24 VDC power supply check to DRIVE
2
ASSY PRO (IBT Cleaner Retract Motor)
The voltage of P414-3 ↔ P414-2 on PWBA
MCU 2 is 4 VDC?
Check after replacement of DRIVE ASSY
3
PRO
Replace DRIVE ASSY PRO.
Does the error recur when a test print is made?
5 VDC power supply check to SENSOR
4
IBT RETRACT
The voltage of P415-3 ↔ P415-4 on PWBA
MCU is 5 VDC?
Continuity check of HARNESS ASSY MAIN
5
Disconnect P/J415 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J415-3 ↔ J107-3
J415-4 ↔ J107-2
J415-5 ↔ J107-1
