Canon IR3300, IR2800, IR2200 manual Resistance of the high-voltage cord white is about 10 k Ω

CHAPTER 4 TROUBLESHOOTING IMAGE FAULTS/MALFUNCTIONS

Transfer guide, High-voltage cord, Composite power supply PCB, DC controller PCB (transfer faulty)

8)Is there foreign matter in the transfer guide assembly or the transfer charging roller assembly, and is leakage noted?

YES: Remove the foreign matter. NO:

1.Check the high-voltage cord for electrical continuity. (The resis- tance of the transfer high-voltage cord is about 10 kΩ.)

2.Check the composite power supply PCB and the DC controller PCB.

Developing assembly

9)Is the developing assembly fitted securely? (Check to see if the develop- ing block members are in firm contact with the photosensitive drum.)

NO: Fit the developing assembly correctly.

Toner level detection assembly (development fault)

10)Is there toner inside the developing assembly? NO:

•Check the toner sensor.

•Check the connectors and the harnesses for electrical continuity. Drum unit, Reader controller PCB, Main controller PCB

11)Try replacing the drum unit. Is the problem corrected/

YES: End.

NO: Real the reader controller PCB and the main controller PCB.

•The resistance of the high-voltage cord for primary charging is about

	10 kΩ
Memo	• The resistance of the high-voltage cord (white) is about 10 kΩ

•The resistance of the cord for the transfer guide is about 10 kΩ
