Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
First of all, thank you very much to the thread gods that got my post up! THANK YOU!
mbaublit, thank you for your reply! Would a dev unit fail suddenly like that or would it be a more gradual process? When I slid the process unit out, it was pretty heavily covered in cyan toner. I've attached a picture (hopefully) so you can see what I was dealing with. It's so thick, you can't even see the label on the dev unit.

Is this a dev unit failure? My main concern is I don't want to throw parts at it, especially if we can eke some further life out of them.Comment

On the back of the developer is a little gear it's usually black and it looks like a cross every time I lost the one color or another it that spins in the mag roller doesn't moveComment

Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
Mbau is right. The devs have a gear on them that needs upgraded. You can use a color when they break, Thats not all that could be wrong. The Black drum is the same color as the color drums. That means they are aftermarket drums, at least the black one. You need to run the DPC drum calibrations ASAP. When the HVT and the drums are out of whack they can dump toner up on top of each other like in the pic. I seen it happen on a high speed machine just with test prints! I have seen the aft. drums work good in the low speed models. I wont use them in the highspeed models. The HVT PCB doesnt like these drums. Buy all new OEM drum units. Replace the gears and have another tech double check it.I have used Canon Imagerunner parts for sale. Most are floor model Color and / Advances Imagerunner with some 3025 3235 parts.

Alright, I'll open it up as soon as I get a spare minute and will let you know what I find.
IIRC, I had to salvage the drums out of another machine and they weren't an exact match, so I had to swap a small part on them to get it to work properly with the C5051. On the black drum though, I think I had to notch something in order for it to fit. The old machine may have been a C5035, but I don't quite remember.Comment

New dev propeller(lol) comes with a pin to put through the shaft. The coupling on the machine itself breaks sometimes too..Comment

Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
This threads title is click bait. Toner dumping...sounds like the old C5800 toner /Dev dumping lol. I have replaced plenty pinned gears but still have not had to replace coupler on machine side.
We have not seen any issues with the stop pads. Would like to see that whole PDf.I have used Canon Imagerunner parts for sale. Most are floor model Color and / Advances Imagerunner with some 3025 3235 parts. Several intact machines being parted.Comment

Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
Well, I removed the cyan developer and the gear on the back looked ok to me.

I also checked back into the opening and the coupling looked ok as well. At least it was comparable to the other 3. I put it back together and ran another PG10 to see if maybe there was a loose connection or something that was resolved and got the following result.

The cyan ghosting is new, probably from shaking the dev around when I removed/replaced it as I wasn't getting any cyan before. I'm still getting the little black chunks of plastic on the sheets though. If you look carefully about 3/4s of the way down on the left hand side, you can just make them out. Those aren't toner smears, they're actually small, sharp pieces of black plastic, partially embedded in the paper.
@techandtrader - It's been a while since I swapped the drums around, a year or more. I'm sure it didn't help the current situation any, but we're so cheap here, it's crazy.

Looks like the cyan developer is worn out and so is the yellow drum.Comment

Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
Its a 4 page PDF I posted that talks about everything. I've replaced all of the above a few times. Probably done 3000 service calls on 5000 series. Surely you have had the broken patch shutter...this stop pad stops it from breaking..Comment

Re: Canon C5051 dumped cyan toner, replaced toner & cleaning blade, now no cyan
In order not to throw good money after bad, I've only replaced the cyan developer for now. That went rather smoothly. However, it doesn't appear to have solved the issue quite yet as I'm still not getting any appreciable cyan output. I did run the INISET-C after I replaced it. I've attached a new PG10 so you can see what I'm getting now.
