Pixma MG7720 Won't Print

[atloomis]

My Pixma printer is printing blank pages. I have tried following directions in a previous post (disconnect power cord, re-install cartridges, perform cleaning, test print page). Nothing is working. 

I have tried calling Customer Support. They need my phone number from my registered account but don't recognize my number. When I try to review my Canon Account online, I cannot reset the password to get through, but Canon recognizes my email address. 

I am striking out with Canon today. Please help.

Hi atloomis,

When your MG7720 is not printing correctly, please make sure that each ink tank contains ink.

Next, perform 3 deep printhead cleanings.  To perform cleanings, please follow these steps:

 1.  Swipe the HOME screen and then tap Setup on your PIXMA MG7720.

 2.  Tap Maintenance.

 3.  Tap Deep cleaning.

 4.  Tap Yes to clean the printhead.

 5.  Tap Yes to print another Nozzle Check.

If your PIXMA MG7720 still does not print correctly, it would require service.
