Through this question, we would like to differentiate all three divisions of a paper cutting machine: manual, semi-automatic, and automatic versions. So, the difference usually occurs in three parts, and those are set-up, clamp, and knives. These three parts derive the whole function of the machine. In the manual machine, you need to set up the papers, operate the clamps to hold the papers tightly and unlock the knives for cutting. In a semi-automatic machine, setting up the paper and clamping is automatic. But operating the knives is still manual. Coming to fully automatic, all three operations are machine-done. You just have to push the button.
