(4) Remove the two screws (golden) 5 and the four connectors (CN2, CN3, CN4, CN6) to
demount the Low-voltage Power Unit 6 (Tool No.1). Remove the screw B to detach the
AC Inlet Assy C.
(5) Demount the Low-voltage Power Unit FAN 7 by releasing the claw C.
(6) Remove the two screws (black) 8 and the connector to detach the hopping motor 9 (Tool No.1).
(7) Remove the two screws (black) 0 and the connector to detach the fuser motor A (Tool No.1).
Note!
• When reassembling the ID FAN 4, Low-voltage Power Unit FAN 7, check the
attachment direction.
• When reassembling the Low-voltage Power Unit6, check the setting of AC input voltage.
100V series: Install a short plug to the connector CN5
230V series: Do not install a short plug to the connector CN5
• The Low-voltage Power Unit 6 and the AC Inlet Assy C must be replaced in a pair
