Step Check Yes No
1
Check of transparency setting
Does the transparency in use match the
NVRAM setting (which type of transparency
(with or without white margin) is enabled or
disabled.)
Go to Step [3]. Replace the
transparency in
use with a one
that matches the
NVRAM
settings, or
change the
NVRAM setting
and go to [2].
2
Does the error recur when a test print is
made?
Go to Step[3]. End of procedure
3
Check of dirt and foreign bodies on surface
of SENSOR OHP
Open COVER-P/H.
Are there any dirt or foreign bodies on the
SENSOR surface?
Clean to remove
any dirt or
foreign bodies,
and go to step
[4].
Go to Step [5].
4
Does the error recur when a test print is
made?
Go to Step[5]. End of procedure
5
Operation check of SENSOR OHP
The voltage of P408-8 ↔ P408-7 on PWBA
MCU is 5 VDC when white paper is brought to
the sensor sensing area (transparency must not
be used), and becomes 0 VDC when paper is
removed?
Replace PWBA
MCU. (p.432)
Go to Step [6].
6
Power supply check to SENSOR OHP
Disconnect the P/J408 from PWBA MCU.
The voltage of P408-9 ↔ P408-7 on PWBA
MCU is 5 VDC?
Go to Step [7]. Go to Step [9].
7
Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J408 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J408-7 ↔ J603-6
J408-8 ↔ J603-5
J408-9 ↔ J603-4
Go to Step [8]. Replace
HARNESS-
ASSY P/H1.
8
Continuity check of HARNESS-ASSY P/H2
Disconnect the P/J603 from PWBA MCU.
Do all of the wiring below have normal
continuity?
P603-7 ↔ J101-3
P603-8 ↔ J101-2
P603-9 ↔ J101-1
Replace
SENSOR OHP.
(p.359)
Replace
HARNESS-
ASSY P/H2.
9
5 VDC power supply check to PWBA MCU
The voltage of P410-3 ↔ P410-4 on PWBA
MCU is 5 VDC?
Replace PWBA
MCU. (p.432)
Go to Step [10].
10
Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-3 ↔ J502-3
J410-4 ↔ J502-4
Replace LV/
HVPS. (p.435)
Repair broken or
shorted part.
Step Check Yes No
