Why does it print with no color when the cartidriges are full of the correct color?
I have worked/ serviced similar Laserjet Color Printer with same issue.
prints with faded colors or different colors are due the the dust/ toner dust accumulated on the optics (mirrors and lenses) inside the printer, which refect the laser beams to form prints. For instance, red color is formed by a mix of yellow and magenta toners. The color
is replaced by yellow due the the partial or complete blocking of the image laser beam for magenta as the mirrors which
reflect laser beam get covered with dust and toner (which partially
blocks the laser beams). Hence the image is
not produced properly. This needs professional hands for servicing and cleaning of the optics inside the printer. Note that first magenta goes off, followed by
yellow, then cyan and lastly black. This is due to the mirrors
placement inside the printer. Magenta is the last one facing upwards at 45 degrees angle and gets most of the dust and goes off first.
Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer. So, it is advised that you get the printer serviced by any printer repair/ service professional.
(Please note that the mirrors, lenses and scanner assembly inside such
printers is extremely complex and can get damaged very easily
especially the mirrors).
Hope it would help. If you need any clarification, let me know
