Color may be uneven between dark
and light image areas. Select Unidirectional Printing in the Advanced Settings of the printer driver.
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. 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.
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 un-
even 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 .
The type of paper specified in the

loaded in the printer.
