Troubleshooting
Step Check
Check of connection between Photoconductor
1
Unit and CONDUCTOR attached to frame
Is the contact surface of Photoconductor Unit
and CONDUCTOR attached to the frame
deformed or are there foreign objects on the
surface?
Check of dirt and foreign bodies on surface
2
of SENSOR ASSY ADC
Are there any dirt or foreign bodies on the
SENSOR ASSY ADC surface?
Does the error recur when the power is
3
turned ON?
Check after replacement of Toner Cartridge
4
Replace Toner Cartridge of each color.
Does the error recur when the power is turned
ON?
