HVPS flat cable / High-voltage power supply PCB ASSY
 
(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 
from the Pins. And then pull out the High-voltage power supply PCB ASSY in the direction 
of the arrow B to remove it from the Rib.

Harness routing: Refer to “2. Rear side of the machine” and “3. 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. 2-8.)
