Colors in printed images are uneven
Cause
Line Drawing/Text is selected when print-
ing 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 Glossy
Paper or Canon Coated Paper.
The type of paper specified in the printer
driver does not match the type loaded in
the printer.
