Program-controlled paper cutter is one of the more widely used in the printing industry.It is very convenient to use, safe and efficient, but sometimes it can not avoid the occurrence of some failures.For example, when its electromagnetic switch is damaged, it may cause its knife. The bed cannot be lowered during use.

         Sometimes, during the normal use of the program-controlled paper cutter, we may suddenly find that its knife cannot fall normally, and its cutter cannot fall.At this time, the red indicator display on its infrared photoelectric safety device is all on. Yes, but there are no obstacles on its corresponding surface. When we restarted the machine, it found that it was operating normally, but occasionally a similar situation occurred. After our careful analysis and inspection, it was found that an electromagnetic switch on the left side of the machine had failed. When we replaced the switch, the situation could be completely eliminated and the program-controlled paper cutter could work normally.
