G7020 Not printing all colors

[drcsue]

My G7020 (about 6 months old) has plenty of ink in all colors.  I have performed a deep cleaning and head alignment to no avail. Can anyone give me some advice on possible corrective approaches.  Owning this printer has not been up to my Canon experience with other printers and I am about ready to throw in the towel.

Thanks for any help.

Register your product on the Canon support site and then request support. Before you contact Canon run a nozzle check.

I had to execute an ink purge.  I guess these things get air into the ink delivery lines.  It takes a lot of ink, but this solved the problem.
