I recently purchased the Canon Pro 10 secondhand. Before printing anything, I went through all of the cleaning cycles, printer head adjustments, etc (probably more times than I had to) to make sure things were ready to go. I connect to the printer via wifi, and made sure when installing that I selected the printer through Canon IJ network, NOT Bonjour. I work mainly in lightroom (on a calibrated monitor), and made sure to soft proof with the paper's ICC profile and before printing, I made sure color management was handled by lightroom/the ICC profile, and not the printer itself. However, every print has a purple cast to it, especially where there should be blue. I tried uninstalling/reinstalling the driver, printed from photoshop instead of lightroom, and even let the printer manage the colors -- all came out relatively the same. I also printed a color test image, and the colors are off on that as well. The grays have a pinkish hue as well. The only time the colors looked slightly different is when I printed the test image from Preview, bypassing photoshop/lightroom altogether (still not good, and not a match at all to the monitor). At this point, I have no idea what to do. The previous owner gave me refills of precision color ink, so I know that's what is being used, but could that be the reason the colors are off as much as they are? I've included pics of the images I was originally trying to print, along with the most recent nozzle checks, and the two color test image prints (one from photoshop and one from preview).
