OF 4 Fuser Drive Assy RAP
Procedure
Execute Component Control [010-001 Fuser Motor ON]. The Fuser Motor can be heard.
Y N
Check the connections of P/J412 and P/J226. P/J412 and P/J226 are connected cor-
rectly.
Y N
Connect P/J412 and P/J226.
Check the wire between J412 and J226 for an open circuit or a short circuit (BSD 4.1A)
The wire between J412 and J226 is conducting without an open circuit or a short
circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between P/J226-1 (+) and P/J226-2 (-) on the Fuser Motor.
(BSD4.1A) The voltage is approx. +24VDC.
Y N
Measure the voltage between P/J425-1 (+) and P/J425-2 (-) on the MCU PWB (BSD
4.1A). The voltage is approx. +24VDC.
Y N
Measure the voltage between P/J426-1 (+) and P/J426-2 (-) on the MCU PWB
(BSD 1.2A). The voltage is approx. +24VDC.
Y N
Measure the voltage between the P/J510-3 (+) and P/J510-7 (-) at the
Power Unit, (BSD 1.2A). The voltage is approx. +24VDC.
Y N
Replace the Power Unit (PL 11.1).
Measure the voltage between P/J450-1 and P/J450-3 on the Relay
PWB. The voltage is approx. +24VDC.
Y N
Measure the voltage between P/J450-6 and P/J450-2 on the Relay
PWB. The voltage is approx. +24VDC.
Y N
Check the wires and connectors between J510 and J450 for an
open or short circuit.
Replace the Relay PWB (PL 11.1).
Check the wires and connectors between J426 on the MCU PWB and
J450 on the Relay PWB.
Replace the MCU PWB (PL 11.1).
Check the wires and connectors between J425 and J226 for an open or short circuit.
Measure the voltage between the MCU PWB P/J412-2 (+) and GND (-) (BSD 4.1A). The
voltage is approx. +5VDC.

Y N
Go to BSDs 1.1A and 1.2A and check the +5VDC distribution. +5VDC distribution
is OK.
Y N
Repair or replace as required.
Replace the MCU PWB (PL 11.1).
Replace the Fuser Drive Assembly (PL 1.1) If the problem persists, replace the MCU
PWB (PL 11.1).
Check the following wires for an intermittent circuit:
• Between J412-7 and J226-10 (BSD 4.1A)
• Between J412-6 and J226-9 (BSD 4.1A)
• Between J412-5 and J226-8 (BSD 4.1A)
• Between J412-4 and J226-7 (BSD 4.1A)
• Between J412-3 and J226-5 (BSD 4.1A)
If the problem continues, replace the Fuser Drive Assembly (PL 1.1) If the problem persists,
replace the MCU PWB (PL 11.1).
