Don't get me wrong - I really love the Canon PIXMA MP830. Best color photos I have ever printed. Easy and fast duplex printing - both side of the paper. Automatic Document Feeder that takes about 20 - 25 sheets. And the Canon ink is relatively inexpensive.
Just hate it when it doesn't recognize a new cartridge!
that's ridiculous, esp at the price of canon inks
I have a Canon iP6600D photo printer, I actually use substitute inks (but I researched & got good quality ones)
but point is it was a pain at first cause I had to take the chips from the canon cartridge & add it to the replacement* - then what happens is it's not recognised - like the canon ones you're talking about.
But, at this stage you have the option to disable ink checking and you can then
use your "dud" cartridges - as I say, if you're willing to sacrifice the ink-checking
They dont advertise this & it seemed to have worked slightly differently for different cartridges iirc & to be honest I cant remember what exactly has to be done (only had to do it once for each colour) but sure you could find out easy enough.
p.s. forum looks fine here
* JetTec & KMP inks no longer require this
