Cause Corrective Action
You are printing on paper that curls
easily.
Printed colors may appear uneven on the leading edge of paper that is suscep-
tible to curling. Select a stronger level in VacuumStrngth in the Control Pan-
el 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 (VacuumStrngth).")
→P.852
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 print-
er driver.
Printing in Draft 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 Print-
ing.") →P.51
Color may be uneven between dark
and light image areas.
Select Unidirectional Printing in the Advanced Settings of the printer driv-
er.
When borderless printing is used, the
edge of the paper is cut during print-
ing. Thus, ink density may be slightly
uneven at the leading edges.
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 print-
er driver.
(See "Giving Priority to Particular Graphic Elements and Colors for Print-
ing.") →P.51
The Printhead is out of alignment. Adjust the Printhead alignment.
(See "Automatic Adjustment to Straighten Lines and Colors (Head Posi.
Adj.).") →P.839
Allowing printed documents to dry
on top of each other may cause un-
even colors.
To avoid uneven colors, we recommend drying each sheet separately.
Density may be uneven if you use
Glossy Paper or Coated Paper.
In Advanced Settings of the printer driver, choose Highest 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.777
(See "Loading Sheets in the Printer.") →P.802
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.

The Platen suction is too strong. In the Control Panel menu, reduce the level of VacuumStrngth.
(See "Adjusting the Vacuum Strength (VacuumStrngth).") →P.852
Close the blue Switch on the platen so that it matches the paper size.
(See "Setting the Blue Switch on the Platen.") →P.1063
