(6) Print head alignment

The printer has a print head alignment function (print head position adjustment function). As it is not

necessary to perform print head alignment at setup or installation of the printer, the function is only briefly

introduced at installation.

Print head alignment: This is a function to correct displacements between the nozzle lines of the print

head, and incorrect print position at bi-directional printing.

The adjustment is conducted using the printed head position adjustment

pattern.
