If there are blurred lines (ink “bleeds” from lines)
Try a higher Print Quality level.
Use better quality media. HP media is recommended and details are given on
page 10–20.
The printer may be operating in an area where the temperature and humidity are
too high. For environmental specifications, see page 10–5.
If there are blotchy areas (uneven fill density)
Use a different Media Type setting.
If you are not already doing so, try using Hewlett-Packard media.
If you are printing in color, see the table on page 2–5 for a note about which
print-quality/media-type combinations are not recommended.
If there is other pronounced banding in area fills
Some banding is normal, especially in dark or dense area fills. If banding is more
pronounced than expected however, try the following:
Check the print quality recommendations on page 3–18.
For the HP DesignJet 450C or 488CA, run the Color Cartridge Test procedure
(see page 5–8).
If the banding is in a black or gray area, then, in the Setup Sheet, reduce the
Pen Settings/Grayscale %. At the same time, make sure that Pen Settings are
set to “Use settings from tables below,” so that your software’s settings are
overridden.
Alternatively, replace the print cartridges (see page 7–2).
If ink smears after you remove a print
Be sure the ink is dry before you remove the sheet. For recommended
ink-drying times, see page 2–25.
When loading media, select the appropriate Media Type on the front panel.
The printer may be operating in an area where the temperature and humidity are
too high. For environmental specifications, see page 10–5.
