PIXMA TR4720 doesn't print well

[RogerBlair]

I run Windows 11 Pro on a Dell Inspiron laptop. I recently got a PIXMA TR4720 printer/scanner/copier. The printer worked fine until I replaced the black ink cartridge; then things went bad. I'm enclosing links to the Alignment Sheet, the Nozzle Clean report, and a test sheet I printed showing the problem:

How do I fix this?

Thank you for participating in the forum.  Many kudos and thanks for providing the prints.  It seems you have already diagnosed the issue as the new ink cartridge.  I would suggest you coordinate a replacement with the provider - hopefully that was Canon.  If so I'm sure they would be happy to support you by calling Canon USA support, Phone number: 1-800-OK-CANON (1-800-652-2666) Monday to Friday, excluding holidays.

If it is not a Canon cartridge, you can certainly try to get support from your cartridge provider, but since they sent you a cartridge that fouled your printer I suspect you could get less than a fully satisfactory result going down that path.  I suggest that you get a Canon cartridge and contact Canon directly for assistance in cleaning up the mess.  It looks to me like you may need to physically clean the print head and run a number of nozzle cleanings to get the mess cleaned up.

(Written with a VERY red face!) It turns out the problem was operator error--I'd forgotten to remove the tape from the print head of the cartridge; I removed it, and all is well.

Sorry for the hassle.

Yikes!!!  I should have thought to ask that.  Many years ago when I was working more in IT we always asked "is the computer plugged in?"  It was surprising how often the answer was "Uh-oh".  I even did it myself one time.  So, thanks for passing the info along and don't beat yourself up too much!  Life happens.
