Problems with the printing quality
Colors in printed images are uneven
Cause
Corrective Action
Line Drawing/Text
is selected when printing images
in many solid colors.
In
Print Priority
in the
Advanced Settings
of the
printer driver, choose
Image
.
You are printing on paper that curls easily.
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 Panel
menu to increase suction against the paper, and
specify a trailing margin of 20 mm (0.79 in) or more.
(→P.621)
Printed colors may be uneven if you set the
Print
Quality
too low.
Choose a higher level of
Print Quality
in the
Advanced Settings
of the printer driver.
Printing in
Draft
or
Standard
mode is faster and
consumes less ink than in
Highest
or
High
modes,
but the printing quality is lower.
(→P.187)
Color may be uneven between dark and light image
areas.
Select
Unidirectional Printing

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.
When borderless printing is used, the edge of the
paper is cut during printing. Thus, ink density may be
slightly uneven at the edges.
Choose a higher level of
Print Quality
in the
Advanced Settings
of the printer driver.
(→P.187)
The Printhead is out of alignment.
Adjust the Printhead alignment.
(→P.604)
Allowing printed documents to dry on top of each
other may cause uneven colors.
To avoid uneven colors, we recommend drying each
sheet separately.

Coated Paper.
In
Advanced Settings
of the printer driver, choose
Highest
or
High
in
Print Quality
.

button and stop printing.
2.
Change the type of paper in the printer driver and
try printing again.
