The screen printing machine is a machine that prints text and images, and often shows various machine problems during work. As a printing staff, we must be familiar with the following reasons and treatment methods for electromechanical equipment to make the printing process stop smoothly. The following are some common problems and treatment methods organized by Licheng Flat Screen Printer Factory （ https://www.hotairstenter.com/product/flat-screen-printing-machine.html ）.

The first phenomenon of hot air tenter: the semi-automatic operation without stepping on the foot switch. This kind of fault is mostly caused by the damage of the foot switch or the short circuit of the foot switch socket causing a short circuit, and the other is the problem of the manual start button switch. Remedy: Replace with new switches, sockets, button switches, or disassemble and repair related damaged parts.

The second kind of hot air tenter failure phenomenon: when the semi-automatic operation works, the foot switch slides down and then rises after being released. This phenomenon is usually caused by the proximity switch on the left side of the slide seat being damaged or disconnected. Solution: Change the proximity switch or connect the switch wiring. The third kind of screen printing machine fault phenomenon: when the semi-automatic work, step on the foot switch and the vertical slide seat falls, and the printing seat does not move after moving to the left. This problem occurs because the proximity switch on the left side of the horizontal slide is not sensed or is defective. Also, the micro switch in the foot switch will not get stuck, which will cause this problem.

Solution: Adjust the sensing point of the left proximity switch or change the proximity switch, and adjust, repair or replace the micro switch in the foot switch.


The fourth phenomenon of Hot Air Stenter （ https://www.hotairstenter.com/product/hot-air-stenter.html ） failure: stepping on the foot switch during semi-automatic operation, the slider will move to the left and then rise, but not to the right. The onset of this phenomenon on the screen printing machine is that the proximity switch at the upper left of the vertical slide is not sensed or there is a problem with the proximity switch. Solution: Adjust the proximity sensor or proximity switch above.
