7. SUPPLY SPECIFICATIONS
7.1.1 Media Type (Cont.)
NOTES:
1. To ensure print quality and print head life use only TOSHIBA TEC specified media.
2. When using the cutter ensure that label length
(i.e. label pitch should be greater than 38 mm.)
3. When marking black marks on label rolls, the following requirements must be satisfied.
When the gap length is less than 4 mm:
The black mark length should be longer than the gap length.
When the gap length is 4 mm or more:
The black mark should not overlap the gap for more than 4 mm and the following label.
Black marks should be printed on reverse side of the gaps. Also, they should contact or overlap the
preceding label's bottom end line.
4. "On the fly issue" means that the printer can feed and print without stopping between labels.

7.1.2 Detection Area of the Transmissive Sensor

The transmissive sensor is movable from the center to the left edge of media.
The transmissive sensor detects a gap between labels, as illustrated below.
(Min. 6.0 mm when using
the cutter module.)

7.1.3 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.
Sensor should be positioned at
the center of the black mark.
