Question about Canon PIXMA MP780 All-In-One InkJet Printer
Scanning old but good condition photos onto computer, they all have red & black vertical lines. Have tried cleaning everything with no success, it gets worse each time I try.
I had one red line appear when i used the duplex. I happened to notice that the thinner glass window on the scanner was dirty. I cleaned it and now no line appears.
