Question about Canon PIXMA MP780 All-In-One InkJet Printer
Just started to do this. Feed pages into page feeder for copying. A vertical thin black line occurs from top to bottom over the otherwise perfect copy. Its about 1.75 inches from the left margin of the page when the page is fed in top first. I cleaned the glass and its still a problem. Not a problem when copying without the page feeder, and not a problem on regular printing. Happens on both black and white and color copies.
There must be a strip of glass about one inch wide, next to
the large glass. There is the problem !
Clean that strip thourougly. When you use the feeder the pages
are scanned thru the small strip of glass.
