Question about Canon PIXMA MP830 All-In-One InkJet Printer

1 Answer

Vertical Line on copies made from automatic feeder

If I run the automatic feeder to make copies, I get a thin, vertical line, about 1-1/2 inches from the left margin of the paper, going all the way down the page.  I don't get this if I make copies using by placing them directly on the glass.  So, the problem must be in the scanner, but it is not with the scanner glass, which is clean and not scratched.  Can't figure out a way to get inside to the scanner to clean whatever must be causing this.

the best thing is to make a copy using the glass and not the document feeder!If there is no lines on the copy simply lift up the cover and on the left side of the glass will be a thin strip of glass,Clean it with a dampened cloth and all line and marks should be gone1

Good Luck!

Brother MFC-7820N Printer--vertical lines

You need to clean the scanner glass. Also known as the strip glass. It is a 1 inch wide strip of glass that runs from the front to the back. Your documents pass over this glass when they are scanned. Some of the wax crayon probably smeared off onto the glass and now when you scan the scanner sees these marks as stationary and thus records them as solid lines. Just look into the scanner section where your documents are fed in or depending on model, some are just to the left of the large original glass.
Good Luck and thank you for using Fixya.

Dell All in One Printer 962-dark vertical line on photo copies

If you are running your copies through the document feeder then see if the line goes away if you make a copy directly from the glass. If the line goes away then open up the doc feeder assy. by hinging it to the left. Underneath you will find that there is a thin strip of glass that the document passes over when it is scanned. Clean this strip of glass and this should correct your problem. If there is a smudge of dirt or small line, it will come out as a solid verticle line when scanned.

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

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.

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.
