Step
Check Yes No
Possible causative parts:
CARTRIDGE ASSY (K) (PL5.1.18)
SENSOR ASSY CRU (PL5.1.4)
HARN ASSY CRU SNR (PL10.1.9)
PWBA MCU (PL9.1.20)
1
Checking the CARTRIDGE ASSY (K) for installation
Is the CARTRIDGE ASSY (K) installed correctly?
Go to step 3.
Reseat the CAR-
TRIDGE ASSY
(K), then go step
2.
2 Does the error still occur when the power is turned ON? Go to step 3. End of work
3
Checking after replacing the CARTRIDGE ASSY (K)
Replace the CARTRIDGE ASSY (K).
Does the error still occur when the power is turned ON?
Go to step 4. End of work
4
Checking the SENSOR ASSY CRU (K)
Does the number on the screen increase by one, every
time the CARTRIDGE ASSY (K) is reseated?
Checked by [Digital Input] - [DI-a(Control Panel)/CRU
K(PC)] in diagnosis.
Replace the
PWBA MCU.

14)
Go to step 5.
5
Checking the connector for connection
Check the connectors between the PWBA MCU and SEN-
SOR ASSY CRU (K).
Are P/J19 and P/J193 connected surely?
Go to step 6.
Reconnect the
connector(s)
P/J19 and/or
P/J193 surly,
then go to step 6.
6 Does the error still occur when the power is turned ON? Go to step 7. End of work
7
Checking the HARN ASSY CRU SNR for continuity
Disconnect P/J19 from the PWBA MCU.
Disconnect P/J193 from the SENSOR ASSY CRU.
Is each cable of P/J19 <=> P/J193 continuous?
Go to step 8.
Replace the
HARN ASSY
CRU SNR.
8
Checking the power to SENSOR ASSY CRU
Disconnect P/J19 on the PWBA MCU.
Are the voltage J19-7pin <=> J19-8pin, about +3.3 VDC?
Go to step 9.
Replace the
PWBA MCU.
(Refer to Removal

9
Checking the SENSOR ASSY CRU for operation
Measure the voltage across ground <=> P/J19-9pin.
Check that the voltage changes when the paper is inserted
into the sensor detecting point.
Replace the
PWBA MCU.
