I may be making a fool of myself, but here goes with a bit more background.
My current printer (i850) is broken- prints colour stripes and pale intermitent black despite repeated flushing- and I don't know if it's just the printing head (which is
definitely damaged) or something more. I have no idea what a new head will cost (will check this on Mon.) but if it's much more than, say, 50 Euros, I won't take the chance on it being something else and will buy an i865 instead (which will also print CDs and DVDs).
I realize that the i865 uses the BCI-6-colour cartridges (cmy) and 6-photo black and additionally the 3-cartridge for normal black.
Now I recall seeing on some second-source replacements for the 3-cartridges (cmy) that they'd also work in the i865. I still have some 3-cartridges left for the i850 and would like to know if they're usable in an i865 instead of the the 6-cartridges: are the physical dimensions different (they look pretty much the same) or is it the ink formulation that varies.
I guess I'm stingy and just hate to waste things.
