Agree, recheck developer unit/powder. As a temporary test exchange yelow with cyan developer units and make a few test prints.

DVELOP Unit 79% . Original Drum and Toner OEM.

I think itīs not developer , or drum , because i change it , and print same test , and the print itīs exacly the same .
no diference . i think if i change it i will see some diference , iīm correct ?
