Where did all the ink only ???

Have the Prints been a few months, create it just to print A3 and wonder where the ink disappears. I inkjet printers also use professionally for many years and therefore the approximate consumption of the ink white estimate, I can only wonder about the ink usage of this printer. It consumes much more ink to clean the nozzle (when you turn, also takes forever until he is ready) as the expression. Original cartridges can be forgotten, because the pressure is fiercely expensive. A great deal for the company. Canon selling the cartridges (only the stupid you also get replica cartridges!)
Otherwise: little space for A3, good print quality.
