传真机感热头原理及自检操作潘承强感热头是传真机的执行机构，它的基本原理是利用电阻产生热量并与感热纸适度的加压接触来完成副本图像的记录。在主板移位脉冲的作用下，按数据“１”或“０”向相应的感热头电阻发热体施加或不施加电压信号，加压的电阻体在瞬间内骤然升...
The principle of the thermal head and the self-test of the fax machine The thermal head of the thermal head is the actuator of the fax machine. Its basic principle is to use the resistance to generate heat and make moderate pressure contact with the thermal paper to complete the record of the copy image. In the role of the motherboard shift pulse, according to the data “1” or “0” to the corresponding thermal head resistance heating body with or without applying a voltage signal, the pressure of the resistor suddenly in a sudden rise ...
