Y ou are printing on paper that curls easily . Printed colors may appear uneven on the leading

edge of paper that is susceptible to curling. Increase

the level of suction holding the paper against the

Platen or specify a margin of 20 mm (0.79 in) or more

for the leading edge. ( → P .587)

If you use Glossy Paper , art paper or Coated Paper ,

uneven color density may occur at the trailing edges

of the paper .

Color unevenness may occur if you set the Print

Quality too low , or if High-Speed Printing is

selected.

Choose a higher level of Print Quality in the

Advanced Settings of the printer driver .

Printing in Draft , Standard , or High-Speed Printing

mode is useful in saving time and ink, compared to

printing in Highest or High modes, but the printing

Color may be uneven between dark and light image

areas.

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 , then use

scissors to cut away the edges on the top and bottom.

When borderless printing is used, the edge of the

paper is cut during printing. Thus, ink density may be

slightly uneven at the edges.

Advanced Settings of the printer driver .

The Printhead is out of alignment. Adjust the Printhead alignment.

Drying documents stacked on each other may cause

uneven colors.

T o avoid uneven colors, we recommend drying each

sheet separately .

If you are using heavyweight sheets or similar paper ,

colors may be uneven on the trailing edge in some

cases even after you execute Adj Far Ed Feed .

For heavyweight sheets or similar paper , execute Adj

Far Ed Feed with the Front T ray Guides raised. Also

keep the Front T ray Guides raised during printing.

Before printing on paper other than heavyweight

sheets, lower the Front T ray Guides .
