Note!
CN6: A connector used to switch the AC input voltage setting
100V short plug is mounted/ 230V short plug is not mounted.
(1) Take the cassette Assy out.
(2) Remove the print engine controller PCB. (See section 4.2.9)
(3) Remove the control PCB. (See section 4.2.8)
(4) Remove all cables from Guide cable PowerLow.
(5) Remove the fuse I/F connector from low voltage power supply, disengage the
claws (2 places), and remove the Guide cable PowerLow .
(6) Remove the two screws (silver) and four connectors (CN1, CN2, CN3), and
remove the low voltage power supply .
At the same time, remove the screw and remove the AC inlet Assy .
(7) Disengage the claw C and remove the low voltage FAN .
(8) Disengage the claw D(2 places) and claw E, and remove the motor cover .
(9) Remove the 3 or 4 screws (silver) and connector, and take the fuse motor out.
(10) Remove the three screws
(silver) and connector, and take the ID motor out.
Notes! • Be careful to install the low voltage FAN in the proper direction.
• Please confirm the setting of AC input voltage when installing the low
voltage power supply .
100V: the short plug is mounted to the connector CN6
230V: the short plug is not mounted to the connector CN6
• Low-voltage power supply and AC Inlet Assy should be replaced
together.(The pair of low-voltage power supply and AC Inlet Assy meets
the safety standards.)
• The number of screws varies between fuser motors.
Three screws: 43963301 (Sanyo)
Four screws: 43070601 (Nidec)
Warning
Risk of Electric Shock
There is a risk of electric shock during replacement of the low voltage power
supply.
Use insulating gloves or avoid direct contact with any conducting part of the
power supply, and caution should be exercised during replacement.
The capacitor may take one minute to complete discharge after the AC cord
is unplugged. Also, there is a possibility that the capacitor doesn’t discharge
because of a breakage of the PCB, etc., so remember the possibility of
electric shock to avoid electric shock.
