Question about Canon PIXMA MP780 All-In-One InkJet Printer
Are you scanning both black and white and color the same way? The ADF (automatic document feeder) uses a different scanning area than when you place the document on the scanning glass. If you open the scanner cover, look to the left of the main scanner glass to the narrow strip used for the ADF. Make sure this narrow strip is clean -- no ink or white-out or scratches. This can make your copies look dirty or smudged.
