Problems with the printing quality

Colors in printed images are uneven

Line Drawing/Text is selected when printing images
in many solid colors.
You are printing on paper that curls easily.
If you use Glossy Paper, art paper or Coated Paper,
uneven color density may occur at the trailing edges
of the paper.
Color unevenness may occur if you set the Print
Quality too low, or if High-Speed Printing is
selected.
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.
Drying documents stacked on each other may cause
uneven colors.
If you are using heavyweight sheets or similar paper,
colors may be uneven on the trailing edge in some
cases even after you execute Adj Far Ed Feed.

Image Edges are Blurred or White Banding Occurs

The Platen suction is too strong.
The Printhead is set too high.

Cause
Cause
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 suction holding the paper against the
Platen or specify a margin of 20 mm (0.79 in) or more
for the leading edge. (→P.587)
In Advanced Settings of the printer driver, choose
Highest or High in Print Quality.
(→P.212)
Choose a higher level of Print Quality in the
Advanced Settings of the printer driver.
Printing in Draft, Standard, or High-Speed Printing
mode is useful in saving time and ink, compared to
printing in Highest or High modes, but the printing
quality is lower.
(→P.212)
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.
(→P.212)
Adjust the Printhead alignment.
(→P.571)
To avoid uneven colors, we recommend drying each
sheet separately.
For heavyweight sheets or similar paper, execute Adj
Far Ed Feed with the Front Tray Guides raised. Also
keep the Front Tray Guides raised during printing.
Before printing on paper other than heavyweight
sheets, lower the Front Tray Guides.
Corrective Action
Set VacuumStrngth to Weakest.
(→P.587)
Lower the Printhead.
