Are you using or have you always used Canon OEM ink. If that is not the
case your luck ran out.

Hi all.

My Canon IP40000R worked fine for months but I've noticed when I print greys
(like a drop shadow or any percentage of black) on lowest quality settings,
it's OK.

If I select glossy or matte papers or increase the quality of print above
standard, the colours all shift - the grey goes pink, blue goes to
mauve/purple. Just one example. Happens from several PCs.

Happens from all apps, I have the 1.8 XP driver from their website... and
getting fed up!

Any suggestions please!
