● Error message
29-008 : Machine cannot read the resistance of yellow imaging unit
29-009 : Machine cannot read the resistance of magenta imaging unit
29-010 : Machine cannot read the resistance of cyan imaging unit
29-011 : Machine cannot read the resistance of black imaging unit
● Symptom :
Contact of the OPC unit is abnormal or high voltage part has some problem. So, the resistance of the
charge roller can not be read in a normal area.
● Possible Cause:
1. The proper current value is not sensed by a wrong installation of the imaging unit.
2. High voltage has not occurred.
3. The current value is not sensed by a HVPS defect.
● Troubleshooting method :
[case2] High voltage has not occurred.
[case1] The proper current value is not sensed by a wrong installation of the imaging unit.
[case3] The current value is not sensed by a HVPS defect. Æ Replace the HVPS board.
Check the high voltage contact between SET and imaging unit.
① Take out the imaging unit and check the HV contact in SET.
② Check if the HV contact of the Imaging Unit is contaminated.
Check if the HVPS connector is connected properly.
