Yes, I have changed everything without any good result (transfert belt, laser unit, HV1, HV2, etc). The problem still persist, does anybody have a suggestion?

you have too much CYAN ..not green. Y & C = G.

look at the dispensing ratios

gradation adjust is not PARTS but a service mode function. replacing parts should be done AFTER calibrations/adjustments have failed.

So you're not even going to look at the consumables, like imaging units? In addition to cyan massively overtoning, magenta is massively undertoning. You must have been talking to the hotline: "Oh yeah, it's got to be a board..."

Hi all,
I would like to mention that I am a field engineer so the first thing I have done was to change the IU. When I say green I understand that Green is mix of Cyan and Yellow. So any feedback would be much appreciated. Thanks all
