Description
This machine prints by the bidirectional mode (in which the heads perform printing during both their
outbound pass and return pass) . This printing method is called "Bidirectional Printing . " This method offers
the advantage of being able to shorten output times, but subtle misalignment occurs during the outbound
and return passes . The procedure to correct this and eliminate misalignment is "Bidirectional Correction . " This
misalignment varies according to the print heads height and the thickness of the media, so we recommend
performing correction to match the media you are using .
