I have a PIXMA G7020 that has started printing colors incorrectly. I saw another post which discussed a similar situation which didn't resolve with repeated deep cleaning and required a replacement printhead to correct the issue.
My first nozzle check print printed black, cyan, and magenta but not yellow. After deep cleaning a couple times, it printed all colors but yellow was faint. After further cleaning, it is only printing black and magenta.
I've attached a picture of the nozzle check printouts. I've also attached a screenshot of the ink levels.
Thanks in advance.
If you have done multiple cleanings and a ink flush and the issue persists, then your printer has experienced an internal hardware issue and would need to be replaced.
If your printer is out of it's 1 year warranty, you would qualify for the Canon 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.
