Adjusting color density and balance
Over the life of the printer, colors may change. For example, reds may begin to
take on a purple cast, or blues may take on a green cast. This happens during the
normal use of a color printer and can be easily remedied by using the color
adjustment procedure described in this section
This front panel procedure involves printing a test page and adjusting the
densities and colors based on the appearance of the test page. You may need to
repeat this procedure and test your adjustments until you achieve the desired
effect.
Note
At any time, you can reset the printer to the factory defaults by
selecting
Color Defaults
from the Color Adjust Menu.
