My first printer was a VERY expensive BJC-4000 and it printed great... so long as I printed every few days. Let it sit too long and you were looking at clogged heads. My in-laws and I never got to use the color cartridge from that printer, because lack of use allowed the head to clog perminantly.
I went with HP after that, and never had those problems again. Naturally, the first time I give Canon another shot, more of the same. My son's iP3000 printed with minor streaking right out of the box. Several cleanings didn't help. After a few weeks, he finally did a few deep cleanings in a row, and it seems to be OK... for now. Hell, even mine is OK at the moment, using generic tanks. Damn things are too fussy. Exactly why I bailed on Canon in the first place!
