[CQ] Bizhub c308 - Yellow Background

[concept001]

Hi All,

We have a c308 that has yellow background on prints, I've tried a few things, swapped out the yellow DV unit, Yellow DU, charge Board and even tried a laser unit from another machine.

But the yellow comes back after a couple of prints, has anyone else had this issue ??

a sample/photo of problem is better than a lengthy of writing hehe .

have you tried background data reset and stabilize followed by checking the ATDC levels for consistency then a complete set of gradation adjustments?
thats what i'd try.

Drum is new and oem?

Swap out the other drums especially cyan and magenta . That was my fix that makes no sense.

Hope that helps,
