Bidirectional Adjustment

When printing with four colors, Cyan (C), Magenta (M), Yellow (Y), and Black(K), this machine can perform

"Bidirectional Printing" which means that the head prints when moving in out and home directions. The

bidirectional pri nting is much faster, but subtle misalignment occurs during the outbound and return passes

which reduces image quality.If the bidirectional adjustment is inaccurate, the print quality appears grainy as

shown on the photograph below, results in blurred image. The operation to correct these misalignments is

called "Bidirectional Adjustment" As this misalignment differs depending on head height and media thickness, it

is necessary to perform adjustments for each kindof media.
