HARNESS-
ASSY P/H1.
16
Check after replacement of MOTOR-PH
Replace MOTOR-PH.
Does the error recur when the power is turned
ON?
Replace PWBA
MCU. (p.432)
End of procedure
17
Shape and operation check of 2ND BTR
ASSY
Remove 2ND BTR ASSY. (p.374)
Is 2ND BTR ASSY damaged?
Are the SHAFT-CENT 2ND, FRAME ASSY
BTR and BEARING-BRUSH CAM damaged?
Does any of them operate abnormally?
Replace 2ND
BTR ASSY and
other relevant
parts.
Go to Step [18].
18
Check after replacement of Photoconductor
Unit
Replace Photoconductor Unit.
Does the error recur when a test print is made?
Go to Step [19]. End of procedure
Step Check Yes No
19
Operation check of SENSOR FUSER IN
The voltage of P418-2 ↔ P418-1 on PWBA
MCU is 5 VDC when white paper is brought to
the sensor sensing area, and is 0 VDC when
paper is removed?
Go to Step [23]. Go to Step [20].
20
5 VDC power supply check to SENSOR
FUSER IN
The voltage of P418-3 ↔ P418-1 on PWBA
MCU is 5 VDC?
Go to Step [21]. Go to Step [39].
21
Continuity check of HARNESS ASSY ADC
Disconnect P/J418 and P/J620 from PWBA
MCU.
Do all of the wiring below have normal
continuity?
J418-1 ↔ J620-3
J418-2 ↔ J620-2
J418-3 ↔ J620-1
Go to Step [22]. Replace
HARNESS
ASSY ADC.
22
Continuity check of HARNESS ASSY 2BTR
SENS
Disconnect P/J620 from HARNESS ASSY
2BTR SENS.
Do all of the wiring below have normal
continuity?
P620-1 ↔ J111-3
P620-2 ↔ J111-2
P620-3 ↔ J111-1
Replace
SENSOR
FUSER IN.
(p.369)
Replace
HARNESS
ASSY 2BTR
SENS.
23
Shape and operation check of CAM ASSY-
2ND
Does CAM ASSY-2ND move smoothly
without any damage, and does it enter the
sensor sensing area?
Go to Step [24]. Replace CAM
ASSY-2ND.
(p.376)
Step Check Yes No
