question for other Pixma iP4000 owners

Archived from groups: comp.periphs.printers (More info?)

First, I'm running Mac OS X.4. I bought the Canon Pixma iP4000 back in
April and have had a persistent problem with banding. Canon sent me a
replacement printer, and a replacment print head, to no avail. I've
tried printing from a different computer (another Mac), using different
software, different images, etc. Same result. I've talked to Canon
support about 6 times and they've basically given up.
Anyone else on a Mac (or otherwise) have this problem? It sure seems
odd that more people would be having this problem because I've done
nothing out of the ordinary, printing-wise. I'm using the stock inks
that came with the printer, on Canon Photo Paper Plus Glossy paper.
I really wish I'd taken this thing back to the store for a refund when
I had the chance.
Ugh.
TIA
