Calibrate color
If you are not satisfied with the appearance of colors, you can calibrate the colors
manually to ensure the best print quality.
NOTE: Calibrate the color only when the tri-color and photo ink cartridges are
installed together. The photo ink cartridge is available for purchase as an optional
accessory. For more information, see HP supplies and accessories.
NOTE: If you are using a Windows Mobile, you can calibrate the color using the
Toolbox software for PDAs. For more information, see Toolbox software for PDAs
(Microsoft Windows Mobile).
Color calibration balances color tints on printed pages. It is only necessary if:
•
Printed colors have visibly shifted toward yellow, cyan or magenta.
• There is a color tinge in the gray shades.
Low ink levels in the ink cartridges might also produce incorrect colors.
•

Clean the ink cartridges
If printed characters are incomplete, or if dots or lines are missing from the printouts,
you might need to clean the ink cartridges. These are symptoms of clogged ink
nozzles, which can result from prolonged exposure to air.
NOTE: Before you clean the ink cartridges, make sure the ink cartridge ink levels
are not low or empty. Low ink levels can also cause incomplete characters, missing
lines, or dots on the printouts. You can check the ink level of the cartridges from the
printer control panel, the Printer Status tab in Toolbox (Windows), HP Utility (Mac
OS), or the Toolbox software for PDAs. For more information, see Work with ink
cartridges.
