I'm trying to print fine greeting cards on a Canon Pixma iX6820, working from a color-corrected Photoshop file. If I print the cards one at a time, the color is fine. If I set the printer to print two cards, the color of the second one will be appallingly off -- purple instead of red, etc.
I have checked ink supply, run test print, downloaded new printer driver and all the usual stuff. Has anyone else encountered this problem?
