Hello,

One customer called print quality no good.
I got test print the pattern is so strange, G 100% to 80% changed blue, one yellow block missed, and yellow edged.
The machine displayed P5, P8, P21.
I tried to replace Y drum, Y developing unit, checked transfer unit and print head unit but still same.

Any ideas about this case?

Are you using genuine Konica Minolta toner ?

Yes, genuine toner.
last time i replaced PH unit and solved Y problem, few months later similar issue occurred but this time is C.
