If There are Blurred Lines (Ink “Bleeds” from Lines)
Perhaps you are not using HP media. For details of HP media, see page 3-3 and
the Supplies Source catalog supplied with the printer.
The printer may be operating in an area where the temperature and humidity are
too high. For environmental specifications, see page 11-4. To allow for ex-
tremely dry or humid environments within the specification, see page 3-21.
Did you adjust the drying time in the front-panel menu purely to speed up the
printers output? For details of drying time adjustments see page 3-22.
If There are Blotchy Areas (Uneven Fill Density)
Perhaps you are not using HP media. For details of HP media, see page 3-3 and
the Supplies Source catalog supplied with the printer.
Did you specify the right media type when loading the media? For details of
front-panel media types, see page 3-3. To find out the printers current type of
media setting, see page 7-2.
Note that some media types are not recommended for color prints with large
area fills. See page 3-5.
If the Print Is Too Dark .or the Color Too Saturated
You can make a global adjustment to the amount of black ink used (which
affects most colors too) by adjusting the
Lightness setting. See page 5-9. This
is also available from some drivers, where the feature may be called
“Darkness”.
