I just replaced the Cyan Developer and Drum due. It worked fine before I did this except it was at the end of its life dumping toner (dev.) and leaving streaks (drum) but cyan was there. After installing the new developer and drum and I ran a PG10 page cyan was not there. I also ran the first page in the full adjust calibration. I just put in a new developer that was taken out of another machine after running a cyan test page and it printed cyan on the other printer. However, after installing it on this one I still have no cyan except for the very light cyan cover the entire page. Anyone have any suggestions on what could have happened and what I need to check. I have attached the 2 pages I printed, one from the full adjust and the other the PG10.
