I have a Canon i9900 that is printing reds and pinks where it should be
printing grays. I tried flipping and switching color space and profiles, but
what it came down to was paper selection.
If 'plain' paper is chosen, the colors print pretty close to what I see.
If any other choice of paper, photo, photo glossy, photo matte, etc. is
selected, the images get a rose colored tint.
I suspected a bad color profile, but then I switched the printer to another
computer and it repeated the tinting. On plain paper, it was fine.
On the others, the color was skewed.
Any thoughts or ideas?
Thanks,

Did you simply switch paper (only), did you switch the media type in the
properties section without changing paper, or did you match the media
type with the actual paper being printed upon?
If the media type doesn't match the kind of paper in the printer, a
slight change in color may be expected.
If the color change is large, then probably the print head needs
cleaning. Use the maintenance section of the printer properties to
print first a nozzle check, then followed by cleaning or deep cleaning
if warranted. You may have to clean several times before more drastic
action is required.
The nozzle check will surely tell you if the print head is clogged. If
not clogged, or the colors appear right on the nozzle check then suspect
some other problem than the nozzle. There is a possibility that
something else is wrong with the printer other than the nozzle, either
hardware or software. Investigate this before proceeding.
If the printer is under warranty, try to get a replacement from Canon.
Be sure to remove all non-Canon ink cartridges and replace with Canon
cartridges before taking/sending for warranty repair.
If not under warranty, you will have to remove the print head and
clean. Observe how it fits in the tray so that you can replace it after
removal. Do the removal as a last resort, and be gentle. Try a
bottle of compressed air first; don't blow too close to the print head,
and blow into the nozzles from the nozzle side, not the ink side.
Replace & see if the problem is fixed. If needed soak the print head by
putting several paper towels, folded, on a plate and wet them well with
water. Place the nozzle area onto the towels and let them soak for one
or two hours. Let head dry completely, and see if OK. If not, then add
some Windex Original Formula to the water and try soaking again, using a
new paper towel. If this still doesn't work, you likely need to buy a
new print head, so you can throw caution to the wind. Repeat the
soaking but with some household ammonia added to the water in the
towels. If this still doesn't work, there is probably no hope for the
print head.
