Thermal printer "broken line" reason
The core of the thermal printer core is a heat sensitive sheet, which is a consumable part of the entire movement. The correct use of the thermal printer will directly affect the quality and effect of the print and the life of the movement. The problem of "broken line" is related to the following points:
1) Thermal printers have higher requirements for thermal paper. The heat sensitive sheet is colored by heat to make the thermal paper coated with a chemical coating appear to be colored. If the chemical coating on the surface of the paper is uneven, the larger particles stick to the heat-sensitive sheet, so that the heat cannot be dissipated and the local lattice is burned out. A "broken line" phenomenon occurs. Similarly, printing in a place where the density of air dust is large increases the probability of "broken line".
2) Thermal printer power adapter output voltage is unstable. The voltage is beyond the tolerance of the thermal film and the local lattice will be burned out. A "broken line" phenomenon occurs.
3) In the environment where the air humidity is too high and the temperature is too high, it will affect the print quality and the life of the movement. The print head ages prematurely. A "broken line" phenomenon or illegible writing.
Method for solving thermal printer "broken line"
(1) When “broken line†occurs, first wipe the heat-sensitive sheet with alcohol and check if it is “broken†(impurities stick to the heat-sensitive sheet, but the heat-sensitive sheet has not been burned).
(2) True "broken line", replace the heat sensitive film.
(3) Use high-quality thermal paper recommended by the thermal printer manufacturer.
(4) Use a power adapter that meets the requirements.
