Aligning the print head automatically
A
Press the / button to select ALIGNMENT,
and then press the button.

Select AUTO, and press the button.

Press the / button to select BI-D
2-COLOR, and then press the button to

The adjustment pattern for output is read by the
sensor and the optimum adjustment value is
registered automatically in the printer.
If you are not satisfied with the result of this
alignment, press the button to return to the
previous level, and then select BI-D ALL.
If you are not satisfied with the result of the
BI-D ALL alignment, try UNI-D.
You can also align the print head individually by
selecting BI-D #1, BI-D #2, BI-D #3, or BI-D
#4. Select an ink dot size from BI-D #1 to BI-D
#4 depending on the media you use and the
print mode you want to try.
Aligning the print head manually
Because there is a distance between the print head and
paper, the misalignment may occur by the humidity or
temperature or moving the print head bidirectionally.
In this case, try UNI-D first, and then BI-D 2-COLOR.
If you want to perform a highly accurate adjustment,
try BI-D ALL.
