I'm here again !
Another fault !
Error code E 025 - 0000 on a Canon iRC 2880.
The error appears only when the machine works in color mode.
Not in black/white.
I changed with another device the entire "process assembly".
But the error stays......
What can I go to check?

Check for loose or pinched wires on the (Kit) connector board at J551 and J552.

-------------------------
E025 error code is indicated when a copy in color mode is made.
The toner for each color is fed from the toner retainer, via the hopper assembly, to the drum unit. There are two kinds of toner feeding, one is hopper feeding from the toner retainer to the hopper assembly and another is drum feeding from the hopper assembly to the drum unit.
If all is normal, the toner supply motor (M8-M11) rotates clockwise (CW). If something goes wrong and the motor rotates counterclockwise (CCW), however, the toner supply feed-screw will rotate to cause a change in the output of PS3 through PS6 (with the machine assuming malfunction of the toner supply motor).
To execute correct toner feeding, this machine has a toner feed level sensor (PS3-PS6). This sensor detects the sensor flag mounted on the shaft of the feed screw. This sensor flag executes reciprocating movement by the drive of the toner feed motor. It is the structure that the toner feed screw rotates and the specific amount of toner is fed to the drum unit when the sensor flag moves back and forth once.
At the time of the toner feeding, the DC controller monitors this sensor while driving the toner feed motor. The toner feed motor is stopped when feeding is completed. By executing this, the toner feeding is correctly implemented.
Workaround :

[1] Stirring plate
[2] Agitating plate
[3] Scraping spring
[4] Sensor flag
[5] Toner feed screw
[6] Toner feed motor drive signal
[7] Toner feed motor error detection signal
[8] toner container
[9] Hopper assembly
[10] drum unit
M8 through M11: Toner feed motor (FM2-5597-000)
PS3 through PS5: Toner feed level sensor (WG8-5772-000)
PS6: Toner feed level sensor for black (FK2-0149-000)
If the Toner feed motors (M8 through M11) can be activated in service mode under PART-CHK, suspect a fault at Toner feed level sensor (PS3 through PS6).

There is an ATI on this, take off the grey cover when you open the front door, 3 screws, this will give you access to the pcb where the devs are connected, there are 4 interuptors that get toner dropt on them from the devs. Blow them out, you will need to take off the left hand side door cover/magnet so you can access the yellow dev interuptor. There is a mod that the grey cover that covers the pcb has milor to catch any falling toner.
Good evening !
I found the cause of error !
A false contact by main connector place in the machine (the black connector on the right)
was the cause of the error.
Thank you for your help!
