When I print documents, a vertical black line appears on all the copies if I print more than one page. If I print only ONE page it is fine. Then when I select to print more than one page, it will then add a black link along the edge of the document. This happens no matter the size of the print on the page.
Note: This is not from any scan. I simply have a word doc, or pdf or whatever and when I click to print more than one copy it adds the black line and messes up all my documents.
