Black Toner cartridge
New drum set
All blacks are light grey. It does print black on the color test page however, I cannot get color to calibrate or register. Auto Color registration ends with an error but no code. Color calibration ends with a 5-940
I removed the transfer belt and cleaned the CTD sensor as well. Still fails.. I have reset the printer to factor and loaded latest firmware. I am running out of ideas. Any further suggestions?
