PWBA MCU LV/HVPS
Step Check Yes No
1Check of 2ND BTR ASSY attachment
Is 2ND BTR ASSY attached correctly?
Go to Step [2]. Re-attach, and
go to step [2].
2Does the error recur when restarting the
printer? Go to Step [3]. End of
procedure
3
Continuity check of HARNESS ASSY MAIN
Disconnect the P/J403 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J403-1 ↔ J600-3
J403-2 ↔ J600-2
J403-3 ↔ J600-1
Go to Step [4]. Repair broken
or shorted part.
4 24 VDC power supply check to MOT ASSY
MICRO (2nd BTR Retract Motor)
The voltage of P403-3 ↔ P403-2 on PWBA
MCU is 24 VDC?
Go to Step [5]. Go to Step [10].
5Check after replacement of MOT ASSY
MICRO
Replace MOT ASSY MICRO. (p.399)
Does the error recur when restarting the
printer?
Go to Step [6]. End of
procedure
65 VDC power supply check to SENSOR
2BTR RETRACT.
The voltage of P418-4 ↔ P418-5 on PWBA
MCU is 5 VDC?
Go to Step [7]. Go to Step [10].
7
Continuity check of HARNESS ASSY ADC
Disconnect the P/J418 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J418-4 ↔ J112-3
J418-5 ↔ J112-2
J418-6 ↔ J112-1
Go to Step [8]. Replace
HARNESS
ASSY ADC.

Check after replacement of SENSOR 2BTR
RETRACT
Replace SENSOR 2BTR RETRACT.
Does the error recur when restarting the
printer?
Go to Step [9]. End of
procedure
9
Check after replacement of PWBA MCU
