My Canon MP560 printer has not printed colors properly in a while. I have bought new color cartridges. I have gone through all the maintenance steps like, cleaning, deep cleaning, print head alignment, nozzle check, bottom plate cleaning and roller cleaning. I have checked all the settings both for photo printing and document printing. But nix ! Every time I print the colors are not right. The printer is only three years. I love it and certainly would not want to buy a new one. Looking for hints on the web I found a video clip on YouTube how to wash your print head. So that is what I’m doing now. It’s a last, desperate attempt to get the printer to work properly. The process will take about 8 to 10 hours ! If this doesn’t help I will be very disappointed.
