Pixma MG7720 Error message - The type of print head is incorrect - install the correct print head. It has stopped working.  I have not changed the print head - all lights are solid red with the exception of M and C. I have removed the print head and cleaned it 3 times- still does not work when powered back up.  Assistance on how to fix?

Hi Mich777,


It would appear that your PIXMA MG7720 would require service.  You are eligible for Canon's Upgrade Program. This is for out of warranty units which have been diagnosed to require service, or for some reason are incompatible with a new or upgraded system. This option allows you a one-time opportunity to purchase a replacement product, discounted from the list price.

To help you get up and running quickly, we also offer free standard shipping (if the order is completed by 12:30PM ET). If you would like to take part in this option, please call our Sales Department at (866) 443-8002.  They're available weekdays and Saturdays after 11 AM ET (8 AM PT). Let them know you have been working with technical support and the Canon Upgrade Program was offered.
