The first failure of the paper cutter: when it is semi-active, it does not step on the foot switch and acts immediately.
        This kind of phenomenon is usually caused by damage to the foot switch or water in the foot switch socket causing a short circuit. The other is that there is a problem with manually starting the button switch. The remedy is to replace the new switch, socket, push button switch, or disassemble and repair the damaged parts.
        The second failure of the paper cutter: when the semi-active operation stepping on the foot switch slides down, it spreads and then rises.
        This kind of appearance is usually that the switch on the left side of the horizontal slide is damaged or disconnected. The solution is to replace the close switch or connect the switch.
        The third failure of the paper cutter: when the semi-active operation stepped on the foot switch, the vertical slide is lowered, and the printer will not move after moving to the left.
        The reason for this problem is that the switch on the left side of the slider is not sensed or is in doubt. The solution is to adjust the sensing point of the proximity switch on the left, or replace the proximity switch, and the micro switch in the foot switch is stuck and does not move, which can also cause this problem. The solution is to move the micro switch in the foot switch. Switch adjustment, correction or replacement of new micro switch.
        The fourth fault of the paper cutter: step on the foot switch during semi-active operation, the slide lowers to the left and then rises but does not move to the right.
        The appearance of this phenomenon is that the upper left proximity switch of the vertical slide is not sensed or is close to the switch. There is a problem. The solution is to adjust the upper proximity switch induction or a very good proximity switch.
        The fifth fault of the paper cutter: the ascending action is slowed by half a beat after the action is switched.

        This kind of problem is that the control solenoid valve is clogged with foreign objects or the solenoid valve is defective. The solution is to remove the solenoid valve or replace the solenoid valve.
