A1.3.3 Detection Area of the Reflective Sensor The reflective sensor is movable from the center to the left edge of media.
The reflection factor of the black mark must be 10% or lower with a waveform length of 950 nm.
The reflective sensor should be aligned with the center of the black mark.
The figure below illustrates the relation between the head effective print width and media width.
The figure below shows the effective print area on the media.
Sensor should be positioned at
the center of the black mark.

OTES:
1. Avoid printing in the area 1.5-mm wide from the media edges (shaded area in the above figure).
2. The center of media is positioned at the center of the print heads.
3. Print quality is not guaranteed within 3 mm from the print head stop position (including 1-mm slowup).
4. Average print (black) rate should be 15% or less. For bar code print area, the print rate should be 30%
or less.
5. Line weight should be 3 to 12 dots.
