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 borderless printing is used, the
edge of the paper is cut during printing.
Thus, ink density may be slightly uneven
at the leading edges.
The Printhead is out of alignment.
Allowing printed documents to dry on
top of each other may cause uneven
colors.
Density may be uneven if you use Glos-
sy Paper or Coated Paper.
