2.3.3 Parameters of label paper
BTP-R681 can support label paper printing and set the cutting and initial printing position
accurately. The label paper not only should meet the specifications of thermal paper roll, but
also should meet the following requirements:
Paper type: thermal label paper
Paper supply mode: paper roll
Base paper width (a): 56mm-82.5mm±0.5
Label width (c): 56mm-80mm±0.5
Margin width (b): ≤1 mm
Paper thickness: 0.13mm-0.15mm±0.005(label paper + base paper)
Label height (d): 30mm-300mm
Label space (e): 2mm-10mm
Thermal layer: outward
Paper roll OD (Max): ф83 mm
Light transmittance of the base paper:
＞
60%
Light transmittance of the label and base paper:
＜
20%
Cut position: middle in the label space for the standard configuration, and the cut position is
adjustable
Label positioning accuracy: ≤1mm
Caution:
Please use the recommended paper or its equivalents. Using the paper of low quality might
affect the print quality and shorten the lifetime of print head;
Do not stick paper onto the core shaft;
If the paper is contaminated by chemical or oil, it may discolor or lose heat sensitivity at the
polluted spot, which will affect the print affect;
Do not rub the paper surface with fingers or hard objects, otherwise it may discolor;
When the environment temperature goes up to 70
℃
, paper will discolor. Thus don not use or
store paper under high temperature, high humidity and strong light conditions.
The mark is measured during printing and paper feeding. If the mark height value detected
by the sensor is bigger than the default value (default setting is 13mm), the printer will alarm
paper end.
