Possible cause
The print head nozzles may
be clogged.

on in the printer driver.
The print heads are
misaligned.
The printed image has incorrect or missing colors.
Possible cause
The Ink setting in the printer

The printable side of the
paper is face down.
The Halftoning and Mode
options are set incorrectly
for your document type.
The print head nozzles may
be clogged.
The ink cartridges are low
on ink or one or more ink
colors are empty.
The colors displayed on
your monitor do not match
the printed colors.
The color settings in your
application software or
your printer driver need
adjustment.
Solution
Clean the print heads. See Chapter 4 for instructions.
Turn off High Speed mode if vertical lines are misaligned. See
Chapter 1 for printer driver information.
Run the Print Head Alignment utility to align the print heads for
precise vertical lines. See Chapter 4 for instructions.
Solution
Change the Ink setting to Color. See Chapter 1 for printer driver
information.
Make sure the Media Type setting matches the media you loaded.
Then the printer driver can automatically select other settings for
the best quality. See Chapter 1 for printer driver information.
Remove the paper and reload it with the printable side face up.
See Chapter 2 for instructions.
The Mode setting you select affects many other settings in your
printer driver. The Halftoning setting selects the method used to
lay down the dot patterns in your image. If either setting is
inappropriate for your document type, the color may appear
incorrectly. See Chapter 1 for printer driver information.
Clean the print heads. See Chapter 4 for instructions.
Check the B black and A color ink out lights to see which cartridge
you may need to replace. See Chapter 4 for instructions.
Because your monitor and printer use different technologies to
represent colors, your printed colors cannot exactly match the
colors you see on your monitor screen. See the Color Guide for a
complete description of printed colors.
You can adjust various color settings in your printer driver, and
possibly your application software, to correct color problems in
your image. See your software documentation and Chapter 1 of
this manual for more information.
