3-4 Color Calibration
Scheduling calibration
In general, you should calibrate the iR C2100/2100S at least once a day,
depending on the volume of print jobs. If it is very important to maintain
consistent color, or if the copier/printer is subject to wide fluctuations in
temperature or humidity, calibrate every few hours. To get the best
performance, calibrate whenever there is a noticeable change in print quality.
If you need to split a print job into two or more batches to be printed at
different times, it is especially important to calibrate before printing each
batch. You should also calibrate the iR C2100/2100S after copier/printer
maintenance. However, because the copier/printer may be less stable
immediately after maintenance, wait until you have printed approximately 50
pages before you calibrate.
NOTE: Since printed output from the copier/printer is very sensitive to
changes in temperature and humidity, the copier/printer should not be
installed near a window or in direct sunlight, near a heater or air conditioner.
Paper is sensitive to climate changes as well. It should be stored in a cool, dry,
stable environment, and reams should remain sealed until they are needed.
Print color reference pages, such as the Color Charts (from the Control Panel
or from the Command WorkStation) and the color reference pages included
with the user software (see Getting Started). All of these pages include fully
saturated color patches and pale tints of cyan, magenta, yellow, and black.
Images with skin tones offer a very good basis for comparison. You can save
and compare pages you printed at different times. If there is a noticeable
change in appearance, you should calibrate the iR C2100/2100S.
If the solid density patches (100% cyan, magenta, yellow, or black) look less
saturated with time, show the pages to your copier/printer service technician
to find out whether adjusting the copier/printer can improve output.
Checking calibration status
You can check whether the iR C2100/2100S is calibrated, which calibration
set and output profile were used, and when the copier/printer was last
calibrated:
• Print a Configuration page or Test Page from the Control Panel or the
Command WorkStation.
• When you select a calibration set in Calibrator, the last calibration and the
user who performed it are displayed.
