Eraser printer / Application

Nowadays, the demand for a large amount of printed paper documents in our work is consuming trees rapidly. These paper files are often discarded quickly due to short expiry dates or misprint, which aggravates the waste of tree resources. 'Eraser printer' tries to use ultrasonic color removal technology to change the discarded paper files into new blank paper, so as to save and protect trees by reusing paper.
