Checking matter
1 Is the harness connected between
LED Cleaning Motor and DC
Driver PCB?
2 Can the LED Cleaning Motor
(signal code : 83) be operated
properly in the Function Checking
Mode of Service Mode?
3 Is the Screw Shaft of LED Head
Dirty or transformed? (In this case
an over load is detected.)
4 Can the error be fixed by
replacing the DC Driver PCB?
5 Can the error be fixed by
replacing the Main Control PCB?
Checking matter
1 Is the harness connected to
Surface Potential Sensor (SPS1)
and Main Control PCB?
2 Set the Auto SP Control to OFF,
turn off/on the KIP9000, and take
printing. Is any abnormal image
printed, such as "too dark", "with
dark background" and "too light"?
3 Can the error be fixed by
replacing the Surface Potential
Sensor?
4 Can the error be fixed by
replacing the Main Control PCB?
Checking matter
1 Is the harness connected to the
Density Sensor?
2 Is the Density Sensor or LED
Head dirty with toner?
3 Can the error be fixed by
replacing the Density Sensor?
4 Can the error be fixed by
replacing the Main Control PCB?
Checking matter
