Paper cutter is an indispensable product in printing production, because it has the characteristics of convenience, safety and high efficiency. Like other equipment, failures will inevitably occur during use, which will bring certain adverse effects to production. Therefore, it is important to eliminate the fault in time and ensure the normal operation of the machine.
        In the production process, sometimes the knife bed cannot be lowered, the cutter cannot cut normally, and the photoelectric sensor control device also fails.

        At this time, if all the power is turned off and then turned on again, the photoelectric sensor control device can work normally and the cutter can also be lowered; but after working for a period of time, the same failure will occur again. In this way, it is possible that i and its electromagnetic switch have failed. Only by replacing the electromagnetic switch of the same specification, the normal cutting work can be quickly restored.
