OF 5 Developer Motor RAP
Initial Actions
Ensure that the Front Interlock 1 Switch is actuated
Procedure
Execute Component Control [042-004 Developer Motor ON]. The Developer Motor can be
heard.
YN
Check the connections of P/J409 and P/J213. P/J409 and P/J213 are connected cor-
rectly.
YN
Connect P/J409 and P/J213.
Check the wire between P/J409 and P/J213 for an open circuit or a short circuit (BSD
4.3A)
The wire between J409 and J213 is conducting without an open circuit or a
short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between P/J213-1 (+) and P/J213-2 (-) on the Developer Motor
(BSD 4.3A).
The voltage is approx. +24VDC.
YN
Measure the voltage between P/J451-3 (+) and P/J451-4 (-) on the Relay PWB
(BSD 1.2A).
The voltage is approx. +24VDC.
YN
Measure the voltage between the P/J450-4 (+) and P/J450-2 (-) on the Relay
PWB, (BSD 1.2B).
The voltage is approx. +24VDC.
YN
Go to 7.3.27 Wire Net +24VDC-6. Troubleshoot the circuit between P/
J510-3 and P/J450-4 for +24VDC.
Replace the Relay PWB (PL 11.1).
Check the wiring connectors between P/J451 pins 3 and 4 and P/J213 pins 1 and 2
for an open or short circuit.
The wiring and connectors are OK.
YN
Repair or replace as required.
Replace the Developer Motor (PL 1.1).
Measure the voltage between the MCU PWB P/J409-B12 (+) and GND (-) (BSD 4.3A).
The voltage is approx. +5VDC.
YN
Go to BSDs 1.1A and 1.2A and check the +5VDC distribution. +5VDC distribution
is OK.
YN
Repair or replace as required.
Replace the MCU PWB (PL 11.1).
Replace the Developer Motor (PL 1.1) If the problem persists, replace the MCU PWB (PL
11.1).
Check the following wires an intermittent circuit.
• Between J409-B9 and J213-10 (BSD 4.3A)
• Between J409-B10 and J213-9 (BSD 4.3A)
• Between J409-B11 and J213-8 (BSD 4.3A)
If the problem continues, replace the Fuser Drive Assembly (PL 1.1) If the problem persists,
replace the MCU PWB (PL 11.1).
