Bizhub C352 high toner consumption

[Guest]

Hi,

I have a Konica Minolta Bizhub C352 which seems to using excessive toner. I recently printed 1,250 copies (4 colour letterheads with 5% coverage) and filled the dump bottle.

The service manual says things like cleaning the TCR sensor window on the underneath of the imaging unit. What do these look like?

What other things could I check for that could be causing this high toner consumption, I'm going through toner really quickly.

Thanks

Any thoughts on this guys? My dump bottle looks like pure toner!

How many copies are on the unit? Might be a bad IU for that color. That would do it.

140k but it's multiple colours too. Any other ideas? It's costing a fortune to run

First check your coverage ratio on the C352. if this is the same as your opion check when the C352 makes the pre drive and open one of the doors.
also do this in a run and the transfer if there is also toner between the copies on the belt
Check then the transferbelt if there is toner on it, if so replace the HV.
