After two weeks of operation and having to keep the same pace with the MP640 printer, the cyan and magenta cartridges are already half empty when I am not print pictures. Overall, I printed some thirty black and white pages for most. At this rate and given the price of the pack of cartridges, you can buy a new printer every two months. Really outrageous from a brand like Canon. Then pass or ink? It's simple, it melts like snow in the many automatic cleaning cycles of the machine. Besides ignition idling cleaning dramatically the waiting time for printing the first page.
I am really disappointed with this purchase. This printer may well be aesthetically beautiful, I strongly recommend its purchase if you want to avoid breaking the bank consumables! Especially if you use significantly.
