The main difference between a fax machine and a copier is that a fax machine sends and receives documents via telephone lines, while a copier uses an internal drum or flatbed scanner to produce copies of original documents. A fax machine also typically has a lower resolution than a copier, as it is only capable of sending black-and-white images at a maximum of 200 dots per inch (dpi). On the other hand, a copier can produce high-resolution color copies with up to 600 dpi. Additionally, a fax machine may have additional features such as the ability to send and receive emails, whereas a copier does not.
