Power supply to Toner Motor (K) of Holder Assy (K) (PL12.2.8)
Measure the following voltages at the PWB Drive (PL15.1.15) connector.
P/J51-24 <=> P/J60-2
Is there +24V DC between P/J51-24 <=> P/J60-2.
Go to step 10.
Go to step 9.
9
24V DC power supply to PWB Drive (PL15.1.15)
1. Disconnect the P/J60 connector from the PWB Drive.
2. Measure the voltage between J60-1 <=> J60-2.
Is there +24V DC between J60-1 <=> J60-2?
Replace the PWB Drive.
(Refer to Ch4-4.2.18.5)

Harness Assy TNR (PL12.1.6) continuity check
1. Disconnect the P/J514 connector from the Holder Assy (K) (PL12.2.8).
2. Disconnect the P/J51 connector from the PWB Drive (PL15.1.15).
3. Check the continuity for the following lines.
J514-1 <=> J51-28
J514-2 <=> J51-27
J514-3 <=> J51-26
J514-4 <=> J51-25
J514-5 <=> J51-24
Is the continuity between J514 <=> J51 normal?
Go to step 11.
Replace the Harness Assy TNR
(PL12.1.6).
