Step Check Yes No
1Check of FUSER ASSY attachment
Is the FUSER ASSY attached correctly to the
printer?
In particular, is the connector connected
firmly to the printer?
Is the connector latched normally?
Go to Step [3]. Re-attach, and
go to step [2].
2Does the error recur when the power is
turned ON? Go to Step [3]. End of
procedure
3
Check after replacement of the FUSER ASSY
Replace FUSER ASSY. (p.388)
Does the error recur when the power is turned
ON?
Go to Step [4]. End of
procedure
4Continuity check of HARNESS ASSY
MCU C/L
Allow FUSER ASSY to cool down
before performing work.
Remove FUSER ASSY. (p.388)
Is the continuity normal between all terminals
of J614A ↔ J417 and J614 ↔ J3?
Go to Step [5]. Replace
HARNESS
ASSY MCU
C/L.
WARNING
5Continuity check of FFC-ASSY LV/MCU
Disconnect P/J401 from PWBA MCU and P/
J500 from LV/HVPS.
Do all of the wiring below have normal
continuity?
P401-21 ↔ J500-2
P401-22 ↔ J500-1
Go to Step [6].
Replace FFC-
ASSY LV/MCU.
6Continuity check of HARNESS ASSY AC
Disconnect P/J503 from LV/HVPS and P/J2
from PWBA FUSER CONT.
Do all of the wiring below have normal
continuity?
J503-5 ↔ J2-5
J503-6 ↔ J2-6
Go to Step [7]. Replace
HARNESS
ASSY AC.
7Check after replacement of PWBA FUSER
CONT
Replace PWBA FUSER CONT. (p.410)
Does the error occur when the power is turned
ON?
Go to Step [8]. End of
procedure
8Check after replacement of LV/HVPS
Replace LV/HVPS. (p.407)
Does the error occur when the power is turned
ON?
Go to Step [9]. End of
procedure
9
Continuity check of HARNESS ASSY MAIN
Disconnect P/J1 from PWBA FUSER CONT
and P/J410 from PWBA MCU.
Do all of the wiring below have normal
continuity?
P/J1-1 ↔ P/J410-10
P/J1-3 ↔ P/J410-9
Replace PWBA
MCU. (p.404) Replace
HARNESS
ASSY MAIN.
Step Check Yes No
