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.
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.
Color density may be uneven if you use Glossy
Paper, art paper, or Coated Paper.

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.

Specify No in Auto Cut in the printer driver before

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.
