Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J408 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J408-3
↔
J603-10
J408-4
↔
J603-9
Go to Step [12].
Replace
HARNESS-
ASSY P/H1.
12
Continuity check of HARNESS-ASSY P/H2
Disconnect P/J603.
Do all of the wiring below have normal
continuity?
P603-3
↔
P203-2
P603-4
↔
P203-1
Go to Step [13].
Replace
HARNESS-
ASSY P/H2.
13
Check of resistance value of CLUTCH
ASSY REGI
Disconnect P/J203.
Is the winding resistance between the
terminals of CLUTCH ASSY REGI is 144
Ω
±
10% (20°C)?
Go to Step [36].
Replace
CLUTCH
ASSY REGI.
(p.329)
14
Check of 24 VDC power supply to
MOTOR-PH
The voltage of P409-6
↔
P409-5 on PWBA
MCU is 24 VDC?
Go to Step [15].
Go to Step [36].
15
Continuity check HARNESS-ASSY P/H1
Disconnect the P/J409 from PWBA MCU.
Do all of the wiring below have normal
continuity?
Is the continuity normal between all terminals
of J409
↔
P604?
Go to Step [16].
Replace
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.404)
End of
procedure
Step
Check
Yes
No
17
Shape and operation check of 2ND BTR ASSY
Remove 2ND BTR ASSY.
(p.348)
Is 2ND BTR ASSY damaged?
Are 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
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.
Step
Check
Yes
No
