Step
Possible causative parts:
FUSER ASSY (PL6.1.10)
PWBA MCU (PL9.1.20)
HARN ASSY FUSER (PL6.1.11)
Checking the error
1 Replace to known good paper.
Does the error still occur when printing?
Checking the EXIT SENSOR for operation
Does the number on the screen increase by one, when the
actuator of the Exit Sensor in the FUSER ASSY is oper-
ated?
2
Checked by [Digital Input] - [DI-2(Control Panel)/EXIT
SNR(PC)] in diagnosis.
Warning: Start the operation after the FUSER ASSY
has cooled down.
Checking the connectors of the SENSOR PHOTO(EXIT
SENSOR) in the FUSER ASSY for connection
3 Check the connections between the PWBA MCU and
FUSER ASSY.
Are P/J17 and P/J171 connected correctly?
Checking the HARN ASSY FUSER for continuity
Remove the FUSER ASSY.
4
Disconnect J17 from the PWBA MCU.
Is each cable of J17 <=> P171 continuous?
Checking the power to the SENSOR PHOTO(EXIT SEN-
SOR) in the FUSER ASSY
5 Disconnect the connector of J17 on the PWBA MCU.
Is the voltage across J17-1pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Checking the SENSOR PHOTO(EXIT SENSOR) for oper-
ation
Check the voltage across J17-3pin <=> ground on the
6
PWBA MCU.
Does the voltage change, when the actuator of the Exit
Sensor is operated?
Checking the REGI ROLLs installation
Open the Front Cover and check the REGI ROLLs installa-
7 tion.
Is the ROLL REGI METAL pressed against the ROLL
ASSY REGI by the spring pressure?
Checking the REGI CLUTCH for operation
Does the clutch noise occur?
8
Checked by [Digital Output]-[DO-29(Control Panel)/REGI
CLUTCH ON(PC)] in the diagnosis.
