My biggest disappointment!

This printer is to evaluate my third of the Pixma series of Canon and by far the worst!
The predecessor of the printhead was suddenly broken and limp after 3 years !!! Have only now and then some sheets printed and barely photos. A new print head would have cost me more than 80 and that is the first mess at the customer.
So I decided to thoroughly search and found this unit here on Amazon with relatively good rating, I can not understand in retrospect. Who forgives because here all 5 stars for this scrap ???
Based on the evaluation, I bought the part and after the connection was not listening more to clean the up. I thought I bought a washing machine and a printer. Each printer which has newly come out different cartridges, so you have to buy new ones constantly, although I still had a bag full of home from its predecessor. The course I have thrown away with, worth 25th
Why can not use the same cartridges with new equipment this company, if it is even the same series ???
When finally a sheet was printed, there was constantly in trouble with the printed image, even though I had several times made the print head alignment. Constantly more lines were overprinted and distorted. 4. After orientation we went I do okay.
Already after a week came forward one after the other at 3 ink tanks to change. Since I do not print much, I turn the unit off after printing. After each power has nothing further to do than to clean itself and about 3 minutes. It's obvious that the color runs out like water from the tap. What the hell this crap ???
To date, many customers have already complained that bought a Canon or other printer. This is to mafia states for spare parts and printer cartridges, or to manipulate the printer software. So that the printer can be programmed after a short time to "scrap". Such intolerable conditions are before the Federal Cartel Office and punished !!!
I'll try to avoid printer from Canon in the future and would recommend the device in any way.
