Colors in printed images are uneven

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 print-
ing. 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
Glossy Paper or Coated Paper.
The type of paper specified in the
printer driver does not match the type
loaded in the printer.
Scan Wait Time > Area in the Control
Panel menu is set to Leading edge.
