NOTE: As shown in the sample, gaps between passes are sometimes created in
different directions among patterns. This unexpected change in direction
is caused by an ink jet printer-specific reason, which is an ink jet printer
inevitably performs a periodical cleaning specified by the flashing timer
even during Bi-D pattern printing, so that the printing direction suddenly
changes. However, this directional difference among Bi-D patterns
should not be considered, and you can always confirm and adjust the
pattern correctly by referring to gap amount only.
3. Click the “Previous” and go back to the “BI-Directional Adjustment” menu. And
choose the “Adjust” menu and click the “OK” button.
4. Check the printed pattern and find the misaligned dot type.
