Checking after resetting the TONER CARTRIDGE (Y, M, C
or K).
Remove the TONER CARTRIDGE (Y, M, C or K), and
shake it from side to side.
Reseat the TONER CARTRIDGE (Y, M, C or K), and check
that the lock key is in the lock position.
Does the error still occur when the power is turned OFF and
ON?
Go to step 10. End of work.
10
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 11. Go to step 12.
11
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 16.
Replace the
defective gear(s)
or DISPENSER
ASSY. (Refer to
REP5.1.)
12
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 14.
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.
13
Does the error still occur when the power is turned OFF and
ON?
Go to step 14. End of work.
14
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 15.
Replace the
HARN ASSY TNR
MOT.
15
Checking the power to TNR (Y) MOT (MOTOR ASSY
DISP).
Disconnect J18/J19 from the PWBA MCU.
Is the voltage across P18P/19-3pin <= > 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.
