I have a Canon BJC-2000 with a Windows XP system. It was printing fine but when I tried a "Canon compatible color cartidge" the colors were way off (too green). So I removed it and got Canon 21 cartridges (color and black) and pout them in the same Canon BCI-21e holder (which also has the printheads) but now i get the message onscreen "unsupported cartridge BCI-23--replace with BCI-21e"!!! Any time I try to print something, even a test page, it doesn't print.
I tried resetting the printer, reinstalling the driver, soaking the printhead in a bit of water and wiping it off with a paper towel. Still "Unsupported cartridge"--but it's the right cartridge!
Sometimes i get "cannot communicate with printer."
ANY SUGGESTIONS? THANK YOU
