Ricoh MP4054 Waste Toner Buildup in Drum Unit

Hey folks, I am experiencing many instances lately on different machines where the Drum Units build up waste Toner and start leaking down all over the transport as well as in the trays... I have replaced the Drums and it would come back after a while... Has anyone had issues with the waste toner auger system??? The Waste Toner Containers seem to be getting toner in...Any Bulletins on this??? Thanks in Advance, Laser801

It happened to me in a machine, I think I remember, a gear or some element of the toner recycling set in the attached image broke and residual toner accumulated in the pcu. I can't remember exactly what it was.

sounds like the auger in the back. this is a known issue.

Does the toner conveying system in the Drum Unit rotate correctly?
On a visit I found something similar and it turned out that the unit did not transport the toner correctly, accumulating it, and that is why the gear was in poor condition.

The strange thing is that in Series 04, these references do not appear. So there are 2 possibilities:
- Improved performance and durability.
- They do not want to replace these parts and are forcing the replacement of the Drum Unit.

SORRY: I just realized it's a monochrome model xD lol

it happened to me 6-7 times, but it was always and only the toner screw broken at the end, for the rest, I always checked both the gear and the toner recycling system with its rotating solenoid, but it didn't work for me never happened that they were broken
