Troubleshooting If You Cannot Print as Expected
Phenomenon
Colors in printed images
are uneven
Cause
Line Drawing/Text is selected
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 using Borderless Printing,
the edge of the paper is cut
during printing. Thus, ink density
may not be even at the edges.
The Printhead is out of
alignment.
Drying documents stacked on
each other may cause uneven
colors.
If you use Glossy Paper, art
paper or Coated Paper, color
shading may appear at the rear
edges of the paper.

Corrective Action
Specify Image in the printer driver.
Printed colors may appear uneven
on the leading edge of paper that is
susceptible to curling. Increase the
level of vacuum holding the paper
against the Platen or specify a margin
of 20 mm (0.79 in) or more for the
leading edge. (→"Adjusting the Vacuum
Strength," User Manual)
Choose a higher level of Print Quality
in the Advanced Settings of the printer
driver.
(→"Giving Priority to Particular Graphic
Elements and Colors for Printing," User
Manual)
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, then use scissors 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.
(→"Giving Priority to Particular Graphic
Elements and Colors for Printing," User
Manual)
Adjust the Printhead alignment.
(→P.45)
To avoid uneven colors, we recommend
drying each sheet separately.
In Advanced Settings of the printer
driver, choose Highest or High in Print
Quality.
