PIXMA 4720 - installed new Canon ink cartridges after starter cartridges ran out. Now my print quality is terrible. I've run the maintenance, nozzle cleaning, deep cleaning, head adjustment, roller cleaning.. nothing helps. My printer is less than 4 months old. Canon support is horrible - I work during their "open" hours so unable to speak or even "chat" with tech support. Anyone have any suggestions?

Hi joanio406,
Please follow these steps:
1. Please press the wrench and screwdriver button on your TR4720 one time.
2. Repeatedly press the right arrow key to select Maintenance and press OK.
3. Press OK on Nozzle check and a test page will print.
Once that page prints, please take a photo of that page and then post that image in your reply of my message.
Also, please remove both ink cartridges and place them side by side with the labels showing. Please take a photo of the ink cartridges and please post that image in your reply as well.

Here is an image from my print out. Would you still be able to assist? I need to be able to use this printer in my classroom!
Thank you!

Are they genuine Canon cartridges? If not I suggest you change them, If they are I think the color one may be bad, Canon will replace it if notified.
