I read you replaced the ink tank, but you may need to replace the printhead. I'm
not familiar with this model. I can remember when I used to get Canon inkjets
into the shop for the same issues you're having and they were 1.5 to 2 years old
with much use. Replacing the printhead solved the problem I'd say 98% of the
time and the other 2% had a real hardcore error not worth fixing. It sounds like
the printhead in this model is user replaceable and I'm suprised Canon didn't
recommend it. If it's like it was back then, when you buy the printhead, it will
also come with each ink tank. It may be costly, but unless the tech has one that
is in good shape to test with, then I believe that's your only option, other
than buying a new printer as you sugested.
