Cause Corrective Action
When borderless printing is used, the edge
of the paper is cut during printing. Thus, ink
density may be slightly uneven at the lead-
ing edges. Specify No in Auto Cut in the printer driver before printing. In this case, the paper can be prin-
ted 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.
Choose a higher level of Print Quality in the Advanced Settings of the printer driver.

Allowing printed documents to dry on top of
each other may cause uneven colors. To avoid uneven colors, we recommend drying each sheet separately.
Density may be uneven if you use Glossy
Paper or Coated Paper. In Advanced Settings of the printer driver, choose Highest or High in Print Quality.
