A fax machine is a communication system that is used for sending and receiving documents that contain images and text. The advantage of a fax machine over email is that it sends a physical document to the receiver.
A fax machine is a handy tool since there is no need to scan or print a document after receiving it. This equipment is ideal for documents that require a person's handwritten signature. A person can either buy a stand-alone fax machine that takes up less space or a multifunctional unit that includes a fax machine, a copier, a scanner and a printer.
