Description
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 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 head height and the thickness of the media, so
we recommend performing correction to match the media you are using.

When further correction is required, such as when adjustment made using [SIMPLE SETTING] does not enhance
printing, use [DETAIL SETTING] to make corrections.
For instructions on how to perform the work, refer to P. 30, "Performing the Initial Adjustment (Correcting
for Misalignment in Bidirectional Printing More Precisely)".
