Chapter 2 Troubleshooting
5
Checking the DISPENSE MOTOR (Y, M, C and K) for
rotation.
Does the DISPENSE MOTOR (Y, M, C and K) function
normally?
Checked by [Digital Output] - [Yellow Toner Motor,Magenta
Toner Motor,Cyan Toner Motor,Black Toner Motor] in [IOT
Diag] of diagnosis.
During this check, cheat the interlock switch (HARN ASSY
INTERLOCK AIO).
Go to step 6. Go to step 7.
6
Checking the gears of the DISPENSER ASSY for shape
and operation.
Are the shape and operation of the gears of the
DISPENSER ASSY normal?
Go to step 11.
Replace the
defective gear(s)
or DISPENSER
ASSY. (Refer to
REP5.1.)
7
Checking the connector for connection.
Check the connectors between the PWBA MCU and
DISPENSE MOTOR (Y, M, C and K).
Are P/J18 and P/J181(Y)/P/J182(M) connected correctly?
Are P/J19 and P/J191(C)/P/J192(K) connected correctly?
Example: For Yellow
Go to step 9.
Reconnect the
connector(s) P/
J18 and P/J181
surly, then go to
step 8. or
reconnect the
connector(s) P/
J19 and P/J191
surly, then go to
step 8.
8
Does the error still occur when the power is turned OFF and
ON?
Go to step 9. End of work.
9
Checking the HARN ASSY TNR MOT for continuity.
Disconnect J18 from the PWBA MCU.
Disconnect J181(Y)/J182(M)/J191(C)/J192(K) from the
DISPENSE MOTOR (YMCK) MOT.
Is each cable of J18 <=> J181/182 continuous? or Is each
cable of J19 <=> J191/192 continuous?
Go to step 10.
Replace the
HARN ASSY TNR
MOT.
10
Checking the power to TNR (Y) MOT (MOTOR ASSY
DISP).
Disconnect J18 from the PWBA MCU.
Is the voltage across P18-3pin <= > ground on PWBA MCU,
about +24 VDC when the interlock switch (HARN ASSY
INTERLOCK AIO) is pushed.
Replace the
MOTOR ASSY
DISP or FRAME
ASSY MOT.
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
11
Checking after resetting the PHD ASSY.
Reseat the PHD ASSY.
Does the error still occur when the power is turned OFF and
ON?
Go to step 12. End of work.
12
Checking after replacing the TONER CARTRIDGE (Y, M, C
or K).
Replace the TONER CARTRIDGE (Y, M, C or K), and check
that the lock key is in the lock position. (Refer to REP5.5.)
Does the error still occur when the power is turned OFF and
ON?
Go to step 13. End of work.
