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 un-
even 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 Con-
trol Panel menu is set to Leading

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.")
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 or High
modes, but the printing quality is lower.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.")
Select Unidirectional Printing in the Advanced Settings of the printer driver.
Specify No in Auto Cut 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.")
Adjust the Printhead alignment.
(See "Automatic Adjustment to Straighten Lines and Colors.")
To avoid uneven colors, we recommend drying each sheet separately.
In Advanced Settings of the printer driver, choose Highest or High in Print Quality.
Load paper of the same type as you have specified in the printer driver.

When Scan Wait Time > Area is set to Leading edge, colors may be uneven 110–160 mm
from the leading edge. (The position varies depending on the Print Quality setting.)
In this case, select Scan Wait Time > Area > Entire area.
However, note that printing will now take longer.
(See "Menu Settings.")
