The printer is adjusted at the factory to produce the best possible image quality. All Color LaserWriter 12/600 PS printers come with these default settings in effect. To change the color balance refer to page 254 of the user's guide. This should only be used to make subtle changes to match multiple printers.
NOTE:
One correction to that page of the User's Guide is in the Read Me. On returning to factory default (Step #7), the manual says to first select a color and hold the + and - buttons together. Instead, just hold down the + and - buttons for about 5 seconds and all colors return to the factory default settings.
