Harness Assy OPF PLG (PL17.4.2), Harness Assy OPFREC (PL4.2.9) and Harness Assy
OPF Main (PL15.2.8) continuity check
1. Disconnect the P/J21 connector from the PWBA MCU & HVPS. (Refer to Ch4-4.2.18.1)
2. Disconnect the P/J81 connector from the PWBA Feeder (PL17.4.1).
3. Check the continuity for the following lines.
J81-11 <=> J810-B3/P810-B11 <=> J210-A3/P210-A11 <=> J21-16
J81-12 <=> J810-B2/P810-B12 <=> J210-A2/P210-A12 <=> J21-15
J81-13 <=> J810-B1/P810-B13 <=> J210-A1/P210-A13 <=> J21-14
Is there continuity between each terminal?
Go to step 7.
Replace any Harness Assy with
no continuity.

Actuator Size (PL3.2.21)
While changing the paper size settings, check the Actuator Size operation. (Refer to Ch7.)
Does the Actuator Size operate correctly?
Go to step 8.
Replace the Cassette Assy
(PL2.1.4), or replace the
defective part.

Switch Assy Size (PL17.2.7) signal
1. Insert a Cassette Assy (PL2.1.4) that contains paper.
2. Check the voltages between the following terminals, and compare them with the specified
paper size values. (Refer to Ch7.)
P/J82-1 <=> P/J82-3
P/J82-2 <=> P/J82-3
P/J82-4 <=> P/J82-3
Do the signals match the paper size settings?
Replace the PWBA MCU &
HVPS. (Refer to Ch4-4.2.18.1)
Replace the Switch Assy Size
TRAY 2.
