After the long-term use of the program-controlled paper cutter, many problems will occur. If the program-controlled paper cutter can't cut through, you need to sharpen the machine. First you need to take down the paper cutter and send it to a professional sharpening place for sharpening. After grinding, you need to reinstall the knife according to the reverse procedure of unloading the knife. When cutting with a program-controlled cutter, the cut paper will be slanted.
        If this phenomenon occurs, you need to observe clearly where it is inclined, and you need to push the adjustment screw of the wide pusher forward. The program-controlled paper cutter does not have enough pressure to hold the paper. You need to check whether there is something on the tabletop to block the infrared wall. If there is any, remove it. If not, you need to set the upper and lower limits of the paper press Check if the sensor is misplaced. If this phenomenon really exists after checking, you need to adjust it. If not, ask a technician to come to you for repair.
