Hello, I've struggling with my Canon Pixma G6020 lately. It was printing fine yesterday but now all my prints are faded and have a sort of noise or grainy look to them. I have done multiple nozzle checks, printer head cleanings, test prints and it recently had a ink flush done. I have also removed the printer head to make sure it didn't have anything on it. The ink levels are just below to halfway line so I don't think it needs more ink. Please any help would be amazing!
