Potential control pcb drum - Canon CLC 1120 Color Copier

Dear
It may unable to adjust the control voltage at Bk inductance initialization.

1. Check if the Drum Unit (Bk) is installed.
2. Check the Drum Unit Relay PCB (Bk)
3. Check the Drum Unit Memory PCB (Bk)
4. Check the harness/connector between the DC Controller PCB and the Drum Unit Relay PCB (Bk)
5. Replace the Drum Unit (Bk).
6. Replace the DC Controller PCB.

Thanks.

ATR Sensor error or toner supply error. Abnormal detected patch reading value.
1. Check if the Drum Unit (Y) is installed.
2. Check the Drum Unit Relay PCB (Y) (UN26)
3. Check the Drum Unit Memory PCB (Y) (UN30)
4. Check the harness/connector between the DC Controller PCB (UN09/ J25) and the Drum Unit Relay PCB (Y) (UN26).
5. Replace the Drum Unit (Y).
6. Replace the DC Controller PCB (UN09)

Code
E061-0002
Description
There is a potential control error/there is an APC error.
The primary charging output used at time of printer output and the drum surface potential after laser output is identified as being 200 V or more (i.e., causing a solid black image).
Remedy
- Replace the potential sensor unit. - Replace the laser scanner unit. - Replace the DC controller PCB.

canon copiers model ir6020i show code E000061-0001 what happen wiht my copier and how to solve this problem?

The laser shutter is faulty. The laser unit is faulty. The potential measurement

PCB is faulty. The DC controller PCB is faulty.

Mode of

Detection

0001 As the result of potential control, the drum surface potential (VL2)

of the white background is about 200 V (generating solid black images).

0002 The primary charging output used for print output and the drum

surface potential after laser output has been made are about 200 V

(generating solid black images).

There is a potential control error/there is an APC error.

If the sub code is 0001 As a result of potential control, the drum surface
potential (VL2) of the background is 200 V or
higher (i.e., causing a solid black image).

If the sub code is 0002 The primary charging output used at time of
printer output and the drum surface potential after
laser output is identified as being 200 V or more
(i.e., causing a solid black image).

Fix - Replace the potential sensor unit.
- Replace the laser scanner unit.
- Replace the DC controller PCB

Note. If you are a technician get yourself a service manual before you try anything, you can get one from eBay item # 330407696483

Good luck, keep me posted

IF you are meaning E602 - replace hdd and system software
