My faithful Canon iP7220 Printer suddenly started to misprint. All colors except BLACK print perfectly. New BLACK cardridge did not fix problem. Problem is: On text print out characters are duplicated a small fraction of an inch apart horizontally for 3 or 4 lines followed by several lines printed OK. This repeats thru out the page! As a resuls some graphics are also distorted.
Any ideas or shall I just scrap it out and get another brand printer?
