A fax (short for facsimile and sometimes called telecopying) is the telephonic transmission of scanned-in printed material (text or images), usually to a telephone number associated with a printer or other output device. ... The receiving fax machine reconverts the coded image and prints a paper copy of the document.

The fax machine has a much longer history than you might think! Invented back in 1843 by Alexander Bain, the "Electric Printing Telegraph" was the world's first faxing device.

When sending or receiving a fax, documents that contain mostly text usually take approximately 1 minute per page. For documents that contain graphics (e.g. scans of documents), or for faxes that are being sent through a slow phone line, it may take 5 minutes per page or more to be sent or delivered.

Answer: A fax machine is designed to both send and receive documents so it has a sending part and a receiving part. The sending part is a bit like a computer scanner, with a CCD (charged-coupled device) that scans only one line of a document at a time, and only in black and white.
