Main Motor Not Controlled Rap - Xerox WorkCentre 5687 Series Service Manual

03-397 Main Motor Not Controlled RAP

03-397 The IOT software has detected that the main motor is not being controlled. The soft-
ware that monitors the main motor and the photoreceptor motor was not reset within the
expected time.
Initial Actions
WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the
customer supply while performing tasks that do not need electricity. Electricity can
cause death or injury. Moving parts can cause injury.
• Switch off the machine, then switch on the machine, GP 14.
• Check the fault history file for other 03-xxx fault codes. If the 03-xxx fault codes occur ran-
domly, the cause may be due to electrical noise. Go to the OF10 intermittent Failure RAP.
Procedure
Ensure that the connectors that follow are securely connected:
• IOT PWB, PL 1.10 Item 2.
• LVPS and base module, PL 1.10 Item 3.
• Main drive motor and PWB, (32-55 ppm) PL 4.15 Item 6 or (65-87 ppm) PL 4.10 Item 6.
The fault is still present.
Y N
Perform SCP 6 Final Actions.
Go to Flag 1 and Flag 2. Check the wiring, GP 7. The wiring is good.
Y N
Repair the wiring, GP 7.
Go to Flag 1. Check the voltages at P/J16, pins 1 and 2 on the LVPS. The voltages are cor-
rect.
Y N
As necessary, refer to:
• 01B 0V Distribution RAP.
• 01G +24V Distribution RAP.
Go to Flag 2. Measure the voltage at P/J3 pin 3, on the IOT PWB. Enter dC330 code 04-010,
Main Motor On. Stack the photoreceptor motor code, 09-010. The voltage changes from
high to low and the main motor runs.
Y N
Perform the OF7 IOT PWB Diagnostics RAP. If necessary, install new components:
• IOT PWB, PL 1.10 Item 2.
• Main drive motor and PWB, (32-55 ppm) PL 4.15 Item 6 or (65-87 ppm) PL 4.10 Item
6.
Reload the software, GP 4, Machine Software. If necessary, install new components:
• Perform the OF7 IOT Diagnostics RAP before installing a new IOT PWB, PL 1.10 Item 2.
• Main drive motor and PWB, (32-55 ppm) PL 4.15 Item 6 or (65-87 ppm) PL 4.10 Item 6.
