Xerox DocuColor 12 Printer with Fiery X12 Leaflet

In general, you should calibrate the Fiery 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 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 Fiery after copier maintenance. However, because the copier may be less 
stable immediately after maintenance, wait until you have printed approximately 50 
pages before you calibrate.

Since printed output from the copier is very sensitive to changes in temperature 

and humidity, the copier 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 Fiery.

If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated 
with time, show the pages to your copier service technician to find out whether 
adjusting the copier can improve output.
