MPC25/4500 cyan pcu
Hi all
I was just wondering if anyone else is having a larger than normal failure rate on the cyan pcu, compared to the other colours that is. I have noticed a trend in my machines in the field, that if the customer produces something which uses a large coverage of cyan, the drum seems to fail even at a low mileage. This results in thick banding of cyan on a colour print/copy.
On the latest machine to have this fault, the page % for cyan are as follows; PCU 48%, Dev unit 50% and dev 100%....I've ordered up a dev unit as I've found in the past that just replacing the dev and drum doesn't solve the problem. I was up there yesterday and cleaned the whole lot. The cleaning unit didn't look over full, but the sponge roller next to the charge roller was rather grunged up with toner.
Has anyone expirienced anything like this, or am I just the lucky one.....
Thanks
