My Canon Pixma MP600 has begun to print any color text, clip art or pics with perfect horizontal lines (unprinted, that is). I have gone to maintenance and tried cleaning, deep cleaning and head alignment. Nothing fixes the problem. The cartridges are original Canon, and are still over half full. BLACK text and clip art prints with NO problems.
I use the printer for church broshures and post cards, and it used to do a great job. Anyone have ideas?
