Question about Canon PC-940 Black and White Copier
A thin, vertical line appears on the copies across the entire page, approximately 1 inch from the right margin. What is causing this problem and how can it be fixed?
Tara, if the ink levels are ok, try clean and allignment functions from the tool menu. Use CLEAN UNUSED PAPER.

Here's the link for how to clean the unit... I was going to post the instructions here, but there are pictures that might be helpful to you.
Before doing anything more drastic, I would try this.. let us know how it turns out.. if it doesn't work, we'll go from there.

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.

Do the black lines show up when you use the adf or if you make a copy from the copyboard glass. If the lines only show with the adf > there is a small **** of glass on the left side of the copy board glass > I would clean the slip glass with windex or a damp cloth..... Good Luck
