Replace PWBA
MCU. (p.435)
End of procedure
Step Check Yes No
30
Operation check of EXIT SENSOR in
FUSER ASSY
The voltage of P417-8 ↔ P417-7 on PWBA
MCU is 0 VDC when ACTUATOR enters the
sensing area of EXIT SENSOR, and is
5 VDC when it leaves the sensing area?
Go to Step [33]. Go to Step [31].
31
5 VDC power supply check to EXIT
SENSOR in FUSER ASSY
Allow FUSER ASSY to cool down
before performing work.
Remove FUSER ASSY. (p.415)
The voltage of connector J614A-7 ↔ J614A-6
that connects FUSER ASSY on the printer is 5
VDC?
