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.
Colors may be uneven at the trailing edge
when you print on heavyweight sheets
even if you execute Adj Far Ed Feed.
Scan Wait Time > Area in the Control
Panel menu is set to Leading edge.
When you load paper in the Front Paper
Feed Slot and print, colors may be uneven
at the leading edge of the paper.

printer.

Printed colors may appear uneven on the leading edge of paper that is susceptible to curl-
ing. Select a stronger level in VacuumStrngth in the Control Panel menu to increase suction
against the paper, or specify a leading margin of 20 mm (0.79 in) or more.
(See "Adjusting the Vacuum Strength.")
Choose a higher level of Print Quality in the Advanced Settings of the printer driver.
Printing in Fast or Standard mode is faster and consumes less ink than in Highest quality
or High modes, but the printing quality is lower.

Select Unidirectional Printing in the Advanced Settings of the printer driver.
Specify No in Automatic Cutting 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, and then use scissors or a cutting tool to cut away the edges on the
top and bottom.
