I don't have any word from Canon but I can tell you mine seem to be full cartridges. I have had my printer for a six months and just now replaced all 8. Means little because, how much do I print? And I would guess more than average use. Whatever average is.
EB EOS 1DX and 1D Mk IV and less lenses then before!
Interesting question. I just had my Gray cartridge empty; 3 others were at half or better, and 4 were essentially full. I have been printing mostly 13X19 and most of them were vivid sunsets or verdant greens. Not sure why Gray should empty first. Ah, well . . .
