OLOUR 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.

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.
