Canon G3470 Printer Issues—Frequent Errors, Slow Printing, and High Maintenance Costs

I bought the Canon G3470 printer about a year ago, and I regret it completely. There are too many issues to count! First, before I even finished my first set of ink cartridges, I got a "maintenance box full" error. I replaced it with an original one, but now it’s happening again—even though the cartridges still aren’t empty! Am I supposed to keep buying expensive maintenance boxes forever?
On top of that, this printer is extremely slow and frequently stops mid-print, giving a "paper jam" error even when there’s no paper stuck inside. And now, to make things worse, the colors aren’t printing correctly—reds don’t show up at all, as you can see in the attached image.
This printer has become more of a burden than a solution. I would have saved money just using a print shop! Canon, fix these issues or provide a real solution!
