If the C,M,Y color seems to be fine on the printed calibriation sheet then i guess the issue is happening when you are trying to print a file which have RGB Colors
so i would suggest to apply these settings on your driver
try first to use the sRGB scientific profile then try the sRGB Display
Also If you print through Acrobat Go to File > Print > Advanced
and First check the option Let Printer determine color and try to print with the above driver settings
If the issue still then try to uncheck it .
My Xerox Phaser 7800GX won't print photos or skintones properly. Vector images are mostly ok, but I can tell the colours are sligntly not right. It's worse though with photos, inparticular they are washed out compared with the same image printed from a much cheaper HP 1525n.
It's not a new printer, but has been serviced, and has genuine toners. The transfer belt etc... is showing as plenty of life remaining.
What I've already done:
Word documents etc... print perfectly fine, vector graphics (even on t-shirt transfer papers) print OK, but anything photographic is just wrong... help!!!
Any and all advice appreciated.
