I have a excellent condition, but not brand new, Canon Pixma MX722 printer. I have purchased and installed new, genuine (IE. from Canon) cartridges in it.
Even when I set the print head alignment for black to the highest values (+5) on the printer, I still cannot get crisp black printing. I have run the nozzle cleaning routine.
Edit to respond to comment of Appleoddity
Here is a scan of the latest manual print head alignment sheet: https://i.stack.imgur.com/KODLL.jpg
The printer utility asks which value for each column is best. For the columns C, D, E and F even the high end of the scale (+5) is not enough.

A picture would be worth a thousand words here. I’m assuming by new cartridges you are talking only about ink cartridges? Most likely if you are not getting the print quality you expect it is the printhead that needs to be replaced. However, if the printer has been sitting unused for even a small amount of time, there could be other things clogged like the waste ink pump and lines. It can be fixed but is not typically worth the time, effort and ruined clothes. – Appleoddity – 2018-12-29T17:03:49.963
The printhead might need cleaning, which is not a simple operation. – harrymc – 2018-12-29T19:18:55.853
The problem shown in the image isn't a dirty or bad printhead or even alignment. Alignment can't correct something that far off. That looks like mechanical damage, or at least something requiring mechanical adjustment, or a firmware problem. You might want to contact Canon tech support and see if they can offer any suggestions. Check the user manual and see if that covers this issue. Unfortunately, consumer inkjets are now built to be disposable. There generally isn't even a supply chain for replacement parts because it costs more to repair than to replace. – fixer1234 – 2018-12-30T01:39:31.920
BTW, even for printers out of warranty, the manufacturer will often offer you a discount on a replacement printer so they can continue to sell you ink. – fixer1234 – 2018-12-30T01:40:48.857
