Is the word trembling because the writing machine writes fast?

The word jitter written by the writing machine is not the reason for the high speed. According to relevant public information, the word jitter written by the writing machine is caused by the mechanical principle and structure of the writing machine. Writing machine is a mechanical device, which makes the iron arm on the typewriter move and hit the carbon tape and paper through the keystroke operation of the typist, thus printing words. In this process, due to the different conditions of the ribbon on the iron arm and typewriter, the printed text may be shaken to some extent.
