OPERATIONS MANUAL – 5750440 – REVISION D
Sizing Dots in Columns
C11
When the system prints a single dot, the printing channel has individual access to ink pressure. When
all seven channels print simultaneously, they share the ink pressure. This sharing can produce printed
dots in columns that are slightly smaller in diameter than single printed dots. The column dot
adjustment enables you to eliminate slight size variances between dots printed in rows and dots printed
in columns.
Column dot adjustment requires a menu that is available only after a special initialization. Start by
unplugging the system.
