Problems with the printing quality When borderless printing is used, the edge of the paper is cut during printing. Thus, ink density may be slightly uneven at the leading edges. The Printhead is out of alignment. Allowing printed documents to dry on top of each other may cause uneven colors. Density may be uneven if you use Glossy Paper or Canon Coated Paper. Specify No in Auto Cut in the printer driver before printing. In this case, the paper can be printed without borders on the left and right sides only. Cut the printed document ejected from the printer, and then use scissors or a cutting tool to cut away the edges on the top and bottom.

(See "Automatic Adjustment to Straighten Lines and Colors.") →P.806 To avoid uneven colors, we recommend drying each sheet separately.
