PCB*

(*Provided on models available with a 2nd paper cassette)

(1) Remove screw "a" and take off the inner insulation film.
(2) Remove three screws (two "b" and one "c") from the high-voltage power supply PCB and

engine PCB.

(3) Slightly lift up the high-voltage power supply PCB and disconnect it from the engine PCB.
(4) Pull the spring up and out.
(5) Slightly hold up the engine PCB and disconnect the following harnesses:

• Toner sensor (light-receiver) harness (3-pin, P1)

• Main-LV-engine harness (2-pin, P15)

• 2nd cassette relay harness* (8-pin, P8)

• Heater thermistor harness (2-pin, P6), if the heat-fixing unit has not been removed

• Fan harness (2-pin, P7), if the fan has not been removed

• Toner sensor (LED) harness (4-pin, P10)

• Main motor harness (6-pin, P9)

• Polygon motor harness (5-pin, P12)

• Solenoid harness (2-pin, P13)

"a," "b," and "c": Taptite, bind B M4x12
