Error Code C-0010

Hi there, the error code 7401 means that there is a problem with the toner sensor in the black developer unit (see service manual page 1-4-15), replace the black developer unit and the problem will be solved.

Black drum ATDC replace the black developer unit, also check to make sure the black toner is getting into the black developer unit. Open close the front door to reset the code (Not the Toner door)

e000020 is error with toner unit,
several possibility :
- The toner is empty
- The developer failsto be replenished with starter developer properly.
- Related developing unit
- Ahopper motor error is identified by the detail code of E020. However, it may be identified by E02x according to need.

The 7410 indicates a drum error (see below) the 0163053 is the number of prints made by the printer. The drum was most likely knocked loose when installing toner.

Drum unit non- installing error -
The drum unit is not installed or not installed properly.

Canon ir 9070 error 69

you have a problem with your developer or toner add assemblys toneris not going into your dev unit

c380 indicates auto-toner error for black developer (K).

Check following:

Is the harness between the LGC board and the developer unit drawer connector open-circuited?
Is any harness inside the developer unit or the auto-toner sensor harness open-circuited?
Is the auto-toner sensor connector or the connector CN341 on the LGC board disconnected?

IF connector no problems, then u probably need to replace the auto toner sensor.

e0020 is to do with there not being enough toner in the developer unit.

Firstly it may be a good idea to check/change to toner cartridge.


Switch off and disconnect from mains for the next bit.....
If ok remove the developer roller, cover is above the manual tray on the right hand side then once inside dev unit has connectors at either side, check they are properly seated. If you need to remove the dev there are several black screws around a metal plate all need removing. The roller should be black with toner. May need replacing depending on age and usage of copier.

You have an improper black toner density. Likely your black toner suction mechanism is clogged or the black toner supply clutch is not working.

9-357.
Black toner problem.Probably You have low toner sensor defect.
But try first to vacuum and clean black toner dispenser.You must vacuum whole path wich is used to transport black toner to developer unit.Then if printing B/W print only, you must print 10 full color sheets every 100 copies.
