Troubleshooting
Phenomenon
Colors in printed images are
uneven
Cause

when printing images in many solid
colors.
You are printing on paper that curls
easily.
Printed colors may be uneven if
you set the Print Quality too low.
Color may be uneven between
dark and light image areas.
When borderless printing is used,
the edge of the paper is cut during
printing. Thus, ink density may be
slightly uneven at the 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 Coated Paper .
The type of paper specified in the

type loaded in the printer.
Scan Wait Time > Area in the

Printed colors may appear uneven on the leading
edge of paper that is susceptible to curling. Select
a stronger level in VacuumStrngth in the Control

specify a trailing margin of 20 mm (0.79 in) or more.

Choose a higher level of Print Quality in the
Advanced Settings of the printer driver.
Printing in Fast or Standard mode is faster and
consumes less ink than in Highest quality or High
modes, but the printing quality is lower.

Select Unidirectional Printing in the Advanced
Settings of the printer driver.
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.
