Colors in printed images are uneven

Cause

Corrective Action

Line Drawing/Text is selected when printing
images in many solid colors.

In Print Priority in the Advanced Settings of the printer driver, choose
Image.

You are printing on paper that curls easily.

Printed colors may appear uneven on the leading edge of paper that is
susceptible to curling. 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.")➔User's Guide

Printed colors may be uneven if you set the
Print Quality too low.

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.
(See "Giving Priority to Particular Graphic Elements and Colors for
Printing.")➔User's Guide

Color may be uneven between dark and light
image areas.

Select Unidirectional Printing in the Advanced Settings of the printer
driver.

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.

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.

Choose a higher level of Print Quality in the Advanced Settings of the
printer driver.
(See "Giving Priority to Particular Graphic Elements and Colors for
Printing.")➔User's Guide

The Printhead is out of alignment.

Adjust the Printhead alignment.
(See "Automatic Adjustment to Straighten Lines and Colors.")➔P.97

Allowing printed documents to dry on top of
each other may cause uneven colors.

To avoid uneven colors, we recommend drying each sheet separately.

Density may be uneven if you use Glossy
Paper or Canon Coated Paper.

In Advanced Settings of the printer driver, choose Highest quality or
High in Print Quality.

The type of paper specified in the printer driver
does not match the type loaded in the printer.

Load paper of the same type as you have specified in the printer driver.
(See "Loading Rolls in the Printer.")➔P.14
(See "Loading Sheets in the Printer.")➔P.21

Make sure the same type of paper is specified in the printer driver as
you have loaded in the printer.
1. Press the Stop button and stop printing.
2. Change the type of paper in the printer driver and try printing again.
