Have a bizhub c280 and is making a lot of noise,found that it came from the itb unit.Replaced ITB.The toner recyling unit was full of toner cleaned it no noise.
Now problem is back.
Seems that toner is not being
transported to waste toner box.Checked this by turning gear and toner was transported.
Anybody have a clue ??

I've had the same fault on 2 seperate C220's now.

On both machines I removed the cleaning unit from the ITB and removed the small shutter assembly that feeds the waste from the ITB into the Wastebox, then vac'd out and cleaned n checked everything also made sure that when the cleaning unit was refitted it was properly seated and screws nice and tight.

Since doing the above both machines have run faultlessly, I'm pretty sure this is an assembly fault at the factory as both my machines were low mileage and less than 6 months old.
