You are printing on paper that curls easi-
ly.
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.") ➔ P.539
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 or High
modes, but the printing quality is lower.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.") ➔P.56
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 ejec-
ted 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.") ➔P.56
The Printhead is out of alignment. Adjust the Printhead alignment.

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

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