[linuxxpwin]

Good Day all,

I am havingh an issue with this error code, this code points to the Black deveolper motor. I have checked motor and it is all good, I proceeded to replacing the motor, yet the problem persist. I have check wiring and connections, check my sensors and all is good.

I have since then ordered the dc controller, but I am not 100% convince that this problem is the dc controller.

Does any one have any suggestions?

I have other machine of same model, so dc controller would not be a waste.

The dc controller is certainly not the first place I would go. First try checking for a clog or blockage interferring with toner flow to the buffer unit or drum. Is there a noise? try turning the gear on the toner cartridge to see if it seized up. After inspecting what you can to eliminate blockage...then move on to things like motor or connector or sensors or boards or wiring/connectors as possible causes. Did you test the motor in service mode? (under Part-chk)

[linuxxpwin]

all of the above mentioned I have already done, I have even vacuum the developer and stir toner inside the unit tone did move through. When the start button is pressed Image is placed on the transfer belt, black included then I have the error.

Parts were checked in Service mode all checked out fine.
However I am still not satisfied that the dc controller is at fault.

Check the processing unit drawer connectors. FM2-9461-000 is the machine side and FM2-9445-000is the drawer side.

i have had this issue before with connectors
Also Check for loose or pinched wires on the (Kit) connector board at J551 and J552.

service manual refers to this board as the Process Kit Relay PCB while the parts catalog calls it the Connecting PCB Unit.

*****Have u checked the white drive gear teeth on the Black toner cartridge / remove turn white gear over paper to check rotation/inspect those teeth

I have had E025-003 many times.

Mostly its toner dropped down onto the Toner Rotation Volume sensors ( PS5 and PS6 ) as shown in the picture above by the very kind Teckat.
A blow out will do nicely. Machines here post Dec08 have a modified cable holder to stop the toner dropping down. Improves , but does not eradicate.

As said , which I have seen , it can also be the connectors shown above.
Also common is , especially on machines sitting dormant for periods of time, is the cartridge gear getting stuck. Free off or stick a new toner in.

I have it a couple of times where the whole toner reservoir and feed screw have been compacted. You are better to remove the whole hopper assy to get at it.

Oh , yes , I have also had 1 instance where the drum was seized showing E025.

I went looking at the connectors very closely and found the suggestion by tekat have some merrit.

I did check the connectors closely and found one of the pins sticking further out than that all of the other pins, creating no contact on the machine side of the connector, I am in the process of rectifying this and will further inform everyone when I am through if I am successful.

Good Day all, I have double checked everything, connections are fine, and retested all of the motors, all of the developing motor are NG! and of the toner container motor are OKAY.

I double checked the PIT-relay board and all there is fine. If anyone have another suggestion I will love it, but it seems to be all pointing to the dc controller board.

Would be a first for me , but good luck. Did you re clean everything? New toner cart? Try a new drum?

did u clean the sensors behind the cover underneath the actual toners

****Measure to Prevent an E025 Error Code due to Toner Leakage
Toner leaking from the toner cartridge falls inside the toner sensors (PS3/PS4/PS5/PS6), causing an
erroneous detection and an E025 error (Error in the toner motor).

When removing and installing the toner cartridge, the toner in the supply route between the toner cartridge
and the hopper may leak through the gap between the toner cartridge case and the holder of the machine.

P-1 Position where the toner cartridge is installed
[1] Point of toner leak
The gap between the toner cartridge case and the holder of the machine is covered with a plastic sheet so the
shape of the front unit cable guide on the toner sensor has been changed to prevent the toner from flowing
onto the toner sensor.
clean the inside of the photo sensor area and replace the front unit cable
guide to the new type.

[2] Change Point

When the front unit cable guide is replaced, implement a periodic cleaning of twice a year around the photo
sensor area (PS3/PS4/PS5/PS6).

Clean toner from sensors PS3/PS4/PS5/PS6 and add
tape cover to top of sensors to keep toner from soiling
sensors in the future.

[ Inspected by Canon Inc. ]
Description
Since the error code "E025-0003" was displayed, the toner rotation volume sensor (PS6) was cleaned for solution.
- E025-0003 can be displayed when an error of Bk developing assembly toner supply occurs.
Cause
Since the toner cartridge installation was performed repeatedly, cyan toner fell from the gear in the front side and accumulated on the
toner rotation volume
sensor (PS6).
Field Remedy
1. Check if the toner rotation volume sensor (PS6) is soiled with toner; if so, clean the sensor.
2. If the symptom still occurs, re-fit J2005 and J2007 connectors of the DC controller PCB.
3. If the symptom still occurs, replace the DC controller PCB with a new one.

After cleaning PS3/PS4/PS5/PS6
Add a piece of tape on top each of
PS3/PS4/PS5/PS6 sensors making sure
not to block actuator once they are
reinstalled. To make sure actuator does
not hit tape, manually move gears to
move actuator in and out of sensors
before reinstalling PIT Relay PCB
assembly.

Good Morning

I have completed a thorough check of everything once more, checking sensors, gears, motors, augers, actuators and everything is fine, gears are rotating fine manually, all soft and nice
add tape to sensor where applicable, I can rest assure everything has been double checked, all mtr check in service mode, has turned out to be NG, all ot motor function are fine except for those with the y/m/c/bk motors sensors were check with voltmeter for resistance and is good.

Now awaiting DC Controller.

Sounds like your doing all the right stuff, Let me know if the dc controller fixes this for you. We have never fixed an E025 with that part yet. For us it has always been a wiring or connector issue or toner clog or those sensors like teckat posted.

[linuxxpwin]

I have just learn something new this morning from the owner of the machine, in which they said water got into the machine from the Front, I did some water stains, but never anything of it, it is only this morning I learn about the water situation.

What a bummer!


Linuxxpwin

[blazebusiness]

That info would have been very useful to you earlier! That certainly changes how you would begin to diagnose the trouble. Were those water stains in a spot where water may have gotten on the relay board that teckat showed a pic of in his post? Where exactly were these water stains you saw?

[linuxxpwin]

Basically centered on the frame area, under the waste toner bottle no physical area where it may have tracked down. Well that would led to believe that water may have got into the toner housing and clogged toner but no it is all good there. Everything still stands as before.

DC CONTROLLER. yep lolol
