2) Paper width:80±0.5 mm
3) Paper roll diameter: 80 mm (Max.)
4) Paper thickness:0.065 ~ 0.10mm
2.2.2 Mark paper parameters
Black mark imprint position is on the front side of the receipt when using mark paper. The black mark
reflectivity is no more than15%, the other parts of paper reflectivity should be more than 85%.There are not any
patterns in black mark area, such as ad, and the mark size shall be satisfied with requirements as below:
2.2.3 Paper using attention
Note:
1) Please use good quality paper, otherwise, it will effect printing quality and even reduce printer head life.
2) Don’t make the paper stick on axis.
3) Paper will be fading out or reduced thermal sensitivity if it is polluted by chemical or oil, which will affect
printing effects.
4) Don’t use nail or hard things to clash printing paper, otherwise, it will be fade out.
5) Paper will be fading out if the environment temperature exceeds 70°C. So please take note the temperature,
humidity and illumination effects.
