When any type of paper, other than specified in this manual, is used, it may cause
deterioration of the print quality and thermal head life.
• y Examples of troubles• z
1) Print quality deterioration by using low sensitivity paper.
2) Thermal head wears due to roughness of paper surface.
3) Sticking between heat receipt layer and thermal head, and vibration noise during printing.
4) Print ink disappears on low print durability paper.
5) Electrolytic corrosion on thermal head due to low quality of heat receipt layer.
4.
Avoid printing with no paper loaded. It damages platen and thermal head.
5.
Do not scrabble thermal head with sharp edge or something hard, or give impact. The heat
element may be damaged.
