A Fax Machine is a device designed for transmitting and receiving documents via a telephone line. "Fax" is essentially another term for "copy," implying the creation of an exact replica or duplication of a document. The operation of a fax machine involves scanning a paper document, converting it into an electronic format, and then transmitting it to another fax machine, which subsequently reproduces the document on paper. Fax machines serve as valuable tools for the exchange of contracts, forms, receipts, invoices, letters, and various other types of documents that require signatures or verification.
