2-4 Color Calibration
Measurements
Measurement files contain numerical values that correspond to the toner density
produced by the printer when it prints solid cyan, magenta, yellow, and black, and
graduated tints of those colors.
To create a measurement file, print a page of color patches and then measure the
patches using a color measurement instrument connected to a computer on the
network. The new measurements are automatically downloaded to the EX7750.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more
output profiles and calibration sets are provided with the EX7750. When you calibrate
the EX7750, select the calibration set that corresponds to the typical printing jobs at
your site. This same calibration set can be associated with one or more output profiles.
For more information about output profiles, see

Scheduling calibration

In general, you should calibrate the EX7750 at least once a day, depending on the
volume of print jobs. If it is very important to maintain consistent color, or if the
printer is subject to wide fluctuations in temperature or humidity, calibrate every few
hours. For optimal performance, calibrate whenever there is a noticeable change in
print quality.
If you must split a print job into two or more batches to be printed at different times,
it is especially important to calibrate before you print each batch. You should also
calibrate the EX7750 after printer maintenance.
Because printed output from the printer is very sensitive to changes in

temperature and humidity, the printer should not be installed near a window, in direct
sunlight, near a heater, or near an air conditioner. Paper is also sensitive to climate
changes. Store paper in a cool, dry, stable environment, and keep reams sealed until
they are needed.
