2.4.2
When the logical area for a sheet of paper in the printer is arranged on a physical sheet of paper, the 1st
dot position on the left edge of the paper and the leading edge position of the label on the bottom edge of
the paper are used as references.
The 1st dot position is the left edge reference position for the
maximum printable area.
One of the following methods is used to detect the leading edge position of
the label.
Table 2.4.1 Methods of Detecting the Leading Edge Position of Labels
Method of detecting leading edge
position of label
Description
Black mark detection
The position where a black mark is detected is the leading
edge position of the label.
Gap detection
The position where the leading edge of the label is detected
is the leading edge position of the label.
Figure 2.4.3 Methods of Detecting the Leading Edge Position of Labels
The leading edge position of a label can be corrected by making changes to the leading edge position
adjustment, to account for detection deviation in the detector (caused by deterioration due to aging).
