Fip2.9 Motor Duplex - Oki B6500 Service Manual

FIP2.9 MOTOR DUPLEX

Step
Possible causes:
MOTOR DUPLEX (PL21.1.29)
PWBA DUPLEX (PL21.1.32)
HARNESS ASSY DUP (PL21.1.7)
HVPS/MCU (PL12.1.19)
LVPS (PL12.1.5)
HARNESS ASSY LVPS (PL12.1.1)
Checking HARNESS ASSY DUP for continuity
Remove Option Duplex.
1 Disconnect P/J50 from PWBA DUPLEX.
Does each cable between J2750 and J50 have continu-
ity?
Checking HARNESS ASSY LVPS for continuity
Disconnect P/J27 from HVPS/MCU.
2
Does each cable between J27 and J2750 have continu-
ity?
Checking MOTOR DUPLEX for rotation
Does the motor rotate?
3 Check by the rotating sound of the motor.
Check using Chapter 2 Diagnostic [Duplex Motor,
Clockwise Normal Speed Test].
Checking after replacing MOTOR DUPLEX
Replace MOTOR DUPLEX.
4
Is the problem cleared after replacing the MOTOR
DUPLEX?
Checking the power to MOTOR DUPLEX
5 Is the voltage across P/J27-8(+) and P/J27-7(-) on
HVPS/MCU, 24 VDC?
Checking HVPS/MCU for continuity
6 Disconnect P/J10 and P/J27 from HVPS/MCU.
Is there continuity between P10-1 and P27-8?
Check
1 – 78
