Ricoh C3003 Developer Spilling

Re: Ricoh C3003 Developer Spilling

Wow, never seen this - it's developer indeed. That drum looks pretty worn out. If you want to give that compatible toner another chance I'd swap or refurb the drum unit and try and save the dev unit since it's new. If you remove the dev unit and turn the mag roller manually that buildup dev might find it's way back into the DV unit, otherwise you can help a little with a small paper sheet.

I am looking for the solution... Removing the dev unit and turning the mag roller manually buildup dev goes back. But if you install in the machine again it will spill again. Same unit works fine in other machine.

OK that's even more weird that the unit makes no trouble in other machine. Since the spilling/buildup only appear at the center I would have suspected something PCDU or toner related or maybe too much toner level inside the DEV unit. Back in the days I had issues with dev loss due to bad development clutches with the Aficio 3228c series. I think the MPC3003 uses discrete motors for BK and CMY so I can't imagine anything is wrong on that end.

See the images.....

That looks more like waste toner to me, not developer.

the drum, so to the eye it seems very worn, here the thing could be that a black pcu (black gear) has been placed instead of the color (white gear) they look the same, but the two gears are slightly moved from each other, the pcu enters, but the shaft and the gear work crookedly, and the gear wears out, or the worm screw breaks, and it no longer discharges the waste toner, it can sometimes happen that the gear cracks/opens white coupling in the machine, the crack opens when the PCU is inserted, and the two gears are off axis, and one of the two does not turn, this is a hypothesis

I seem to have understood that the problem is only yellow(?)...well!...try exchanging the yellow PCU with that of another color, and see if the problem moves (and be careful that the gear behind be white)....the developer unit cant turn backwards!

Yes, the problem is with yellow only. Rest are OK. This dev unit is old and taken from a working machine. Worn out drum works fine on other machine. New unit gives the same output. The problem is not with the unit. Its inside the machine.

Removed the drive section completely. Checked each gear. Replaced high voltage boards (Both). Cleaned the toner spilling inside the process unit. Transfer belt checked.

I think it is related to drum charging. When machine is powered ON. Dev unit and Tr belt rotates. During this developer not comes out. When patches start forming on belt developer starts building up and coming out.

Both HVT boards have been replaced. Drum unit replaced. Then why still there is arching or shortage? I guess not sure. This is what I observed.

Ahh, this lovely issue. I've seen this one a couple of times and it took me a while to find out what the hell causes it.

Remove the ITB and remove the belt.
There is a metal roller that is supposed to help drive the belt that has locked up from dirt and grime in its bushings.
I don't remember exactly which roller it is, I believe it is the one that is attached to the part that you bend in and out to release the belt pressure.
Just attempt to manually turn each metal roller and you'll notice pretty quickly which one is locked up, it is one of the ones located at the edges of the ITB.

Removing them is a bit annoying so cleaning them with some contact spray from the outside usually helps.
If you are really unlucky it has begun to dig into the metal roller but I haven't had that happen to me.

interesting, it's never happened to me, but the fact remains that this doesn't explain why only yellow(?)

Your guess is as good as mine as to why only yellow seems to be affected, but I do know that on every machine I've been on with this sort of yellow dev pattern it was always that roller being locked up or heavily obstructed.
I've seen it on the 03-series and 04-series(Which I believe is just the 03-series but with the SOP).

look, I found on goose guide what seems to be the same problem you have on the same model, I'll give you the exact description:

[streaks yellow]

"Pulling developer out of yellow PCDU.ITB unit's Primary Transfer Roller for yellow has seized.
Disassemble and clean the roller & bushings orReplace ITB Assembly"


....Have you tried another ITB unit?
