Question about Canon PIXMA MP780 All-In-One InkJet Printer

Copying with page feed results in a vertical line on every page

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.

Copies are being printed with a line vertically down the side of the page. Only happens when copying using the hopper.


If it's a thin, sharp line, it's just a blob of ball-point pen ink on the scanner glass. Lift the lid, and you'll see the narrow strip of glass that the scanner uses when you feed a document through the feeder. Clean that with a rag dampened with window cleaner, or, better yet, alcohol. Even a dot of ink too small to see will show as a solid black line on anything you copy, scan, or fax via the doc. feeder.
Don't use so much cleaner that it runs under the glass.

Copies leaves lines when put through the feeder,but not on the glass .......have cleaned and sprayed air can everywhere I can think of The Hp Printer is HP 3055 All in One printer


Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page.

If this is your problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

Unwanted verticle line on fax copies

I get lines and can't read the right side of copies that I make with the 1270e. How do I fix this?


You have not specified why you can't read the right side of copies and I am assuming that the reason is because the 'lines' are covering the text. I can offer a solution to the lines issue.

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
