(1) Disconnect the HVPS flat cable from the High-voltage power supply PCB ASSY. Disconnect
the HVPS flat cable from the Main PCB ASSY, and release it from the securing fixtures.
(2) Disconnect the Fan harness from the High-voltage power supply PCB ASSY.
(3) Remove the Screw cup M3x8 (black) screw. Release each Hook and pull out the right side
of the High-voltage power supply PCB ASSY in the direction of the arrow A to remove it

Harness routing: Refer to “8. Rear side of the machine”, “9. Top side of the machine”.
Note:
• After disconnecting flat cables, check that each cable is not damaged at its end or
short-circuited.
• When connecting flat cables, do not insert them at an angle. After insertion, check
that the cables are not at an angle.
Assembling Note:
• After attaching the High-voltage power supply PCB ASSY, push the Electrode springs
from inside of the machine to check that nothing is caught. (Refer to Fig. 2-12.)
