Question about Canon PIXMA MP780 All-In-One InkJet Printer
I have recently been getting a vertical line from the 3ebk cartridge only & only on printing (not a glass cleaning issue on fax/scan/copy). i have run numerous cleaning, head alignments & roller cleaning to no avail - any ideas???
Not sure if this will help but there is a small glass panel to the left of your flatbed scanner- this must be clean or else I get a black vertical line in my printing.

There are a number of issues that cause vertical lines in printing. If you have cleaned all the glass panels and roller,the next primary cause is a blocked printhead but people have success cleaning and refilling cartidges as I do. How old is the cartridge, as they do eventually wear out due to the printhead points wearing out(hold the cartridge to the light and look on the printhead, do the points appear scratched or white dots? This indicates replacement. How much ink is left? When black ink is low but not low enough to show a message, sometimes vertical lines can appear. Try checking ink status, or try refilling ink if you know how. If this issue reoccurs with a new cartridge it more than likely could be the printers printhead and not the cartridge. Cartridges can become clogged if not printed with for a while. Try standing the cartridge on newspaper for a while. Blot it dry and retry it.
