Self-adhesive paper cutter is not good at cutting paper, how to repair it?

1. You can continuously pad several sheets of paper at the lower part of the knife and loosen the screws.

2. If the knife is not sharp, take it to a grinder for grinding, or find a special grinder to sharpen the knife;

3. It will be helpful to cut the glue and stick the knife with some engine oil;

4. Pay attention to the synchronization of the paper cutter and the host, otherwise the paper will easily jump out;

5. Please share it with me, haha, thank you!
