Very unhappy with the life of any of your print cartridges. Don't print very often. Have had to purchase 3 (expensive) since owning. Compared to the HP I had for 10 years, this printer, Pixma MX922, is an ink cartridge hog!!! Replacements are overpriced for the amount of ink within. Printer/fax is soooooo noisy, slow and not at all as expected. Very disappointed!!! Customer service didn't seem to care and only made excuses for the cartridge shortcomings. Made excuses when I called. I had the "so called empty cartridge" checked because the printer would not print and found that it was still 1/2 full. Again, customer made excuses accusing the checker of poking a hole in the cartridge. NOT HAPPY WITH CANON or customer service TO SAY THE LEAST!
