Step Check Yes No
1
Check of connection between Photoconductor
Unit and CONDUCTOR attached to frame
Is the contact surface of Photoconductor Unit
and CONDUCTOR attached to the frame
deformed or are there foreign objects on the
surface?
Clean, and go to
Step [2]. Go to Step [2].
2Check of dirt and foreign bodies on surface
of SENSOR ASSY ADC
Are there any dirt or foreign bodies on the
SENSOR ASSY ADC surface?
Clean, and go to
Step [3]. Go to Step [4].
3Does the error recur when the power is
turned ON? Go to Step [4]. End of
procedure
4
Check after replacement of Toner Cartridge
Replace Toner Cartridge of each color.
Does the error recur when the power is turned
ON?
Go to Step [5]. End of
procedure
5Check after replacement of
Photoconductor Unit
Replace Photoconductor Unit.
Does the error recur when the power is turned
ON?
Go to Step [6]. End of
procedure
65 VDC and 24 VDC power supply check to
SENSOR ASSY ADC
The voltage of P422-2 ↔ P422-4 on PWBA
MCU is 24 VDC?
And the voltage of P422-8 ↔ P422-4 is 5
VDC?
Go to Step [7]. Go to Step [14].
7Continuity check of HARNESS ASSY ADC
Disconnect P/J422 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J422-8 ↔ J431-1
J422-4 ↔ J431-5
J422-2 ↔ J431-7
Go to Step [8]. Replace
HARNESS
ASSY ADC.
8Check after replacement of SENSOR ASSY
ADC
Replace SENSOR ASSY ADC. (p.353)
Does the error recur when the power is turned
ON?
Go to Step [9]. End of
procedure
95 VDC power supply check to SENSOR
HUM & TEMP
The voltage of P413-4 ↔ P413-2 on PWBA
MCU is 5 VDC?
Go to Step [10]. Go to Step [14].
10
Continuity check of HARNESS ASSY MAIN
Disconnect P/J413 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J413-1 ↔ J104-4
J413-2 ↔ J104-3
J413-3 ↔ J104-2
J413-4 ↔ J104-1
Go to Step [11]. Repair broken
or shorted part.
Step Check Yes No
