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. Specify Image in the printer driver.
You are printing on paper that curls easily. 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.
(→P.468)
If you use Glossy Paper, art paper or Coated Paper,
color shading may appear at the rear edges of the
paper. In Advanced Settings of the printer driver, choose
Highest or High in Print Quality.
(→P.193)
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.
(→P.193)
Color may be uneven between dark and light image
areas. 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. When borderless printing is used, the edge of the
paper is cut during printing. Thus, ink density may
be uneven at the edges.
Choose a higher level of Print Quality in the
Advanced Settings of the printer driver.
(→P.193)
The Printhead is out of alignment. Adjust the Printhead alignment.
(→P.453)
Drying documents stacked on each other may cause
uneven colors. To avoid uneven colors, we recommend drying each
sheet separately.
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. 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.
