Adjusting the Color Balance
As the printer is used, ambient conditions and the depletion of consumables (the toner cartridge and drum
cartridge) can gradually cause changes to occur in the four color components of color images, cyan, ma-
genta, yellow, and black. This results in deviations in the color balance.
These deviations in the color balance occur gradually over a long period of time. Ambient conditions (tem-
perature and humidity) and the number of times the printer is used can have a large effect on color devia-
tion.
The printer has two color adjustment functions for the purpose of correcting deviations in the color balance.
These functions are executed from the key operator programs. For details on using key operator programs,
see the Key Operator's Guide.
When should the color balance be adjusted?
• Color adjustment can be performed whenever a noticeable change occurs in the color balance.
• Color adjustment should always be performed when one of the toner cartridges (cyan, magenta, yellow,
or black) is replaced.
Color adjustment functions
The printer has the following two color adjustment functions:
• Color Balance settings
This function is used to adjust each of the density levels (low, mid, and high) of the four color components,
cyan, magenta, yellow and black. Use this mode when the color deviation is large.
• Easy calibration
This mode is used for fine adjustment of the gray balance at the mid density level of the colors cyan,
magenta, and yellow. Use this mode to correct minor color deviations.
