OPERATIONS MANUAL – 5750440 – REVISION D
Adjusting a Single Dot Diameter
C9
This function allows you to change the dot diameter of individual dots from top to bottom by altering the
stroke, in microseconds, of a piston in an ink channel. When the dots in a row are too small, they require
a dot-size increase. If they are too large, they require a dot-size decrease.
Changing individual dot diameters requires a menu that is available only after a special initialization.
Start by unplugging the system.
