C OLOR MENU
The printer automatically adjusts colour balance and density at appropriate intervals,
optimising the printed output for bright white paper viewed in natural daylight conditions.
The items on this menu provide a means of changing the default settings for special or
particularly difficult print jobs.
ITEM SETTINGS EXPLANATION
DENSITY CONTROL AUTO
MANUAL
If set to AUTO, image density will be automatically
adjusted at power on, when a new image drum or toner
cartridge is installed, and at intervals of 100, 300 and
500 drum counts. If a 500 drum count interval occurs
during a print job it will occur at the end of that job, and
will take up to 55 seconds. If set to manual, this
adjustment will only be performed when initiated by the
next menu item.
ADJUST DENSITY EXECUTE Selecting this will activate adjustment of the colour
density.
COLOR TUNING PRINT PATTERN Selecting this item prints the colour tuning pattern to
help you adjust the colour balance.
