The least misalignment
This machine prints by the bidirectional mode (in which the print heads perform printing during
both their outbound pass and return pass). This printing method is called "Bidirectional Printing."
This method oers 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."
