No you're not [too fussy] - I have the identical problem, even after a
new print head, under warranty, numerous cleanings, out of the printer
cleaning, everything possible. I have wasted too much ink, time and
paper, and I will be contacting Canon very soon to demand a full
replacement printer. Perhaps if we all do the same, they will take
notice?
