How does Fax number work?
The sender dials the fax number that the service has assigned to the recipient. The fax machine translates the data and transmits it over the phone line. The service receives the data, translates it into an image file and sends the image to the recipient's e-mail address.
How does FAX work?
A fax machine is designed to both send and receive documents, so it has a sending part and a receiving part. The phone line transmits this information almost instantly to a fax machine at the other end. It receives the electrical pulses and uses them to control a printer.
HOW DOES faxing a paper work?
The machine scans the document. It transfers the image of that document into a signal. That signal is sent down a telephone line to another fax machine. The other machine decodes the signal and reproduces the document.
How long does a fax take?
Sending a fax takes about 30 seconds to 1 minute per page of text (assuming a clear connection for both machines and using today's technology). Graphics, fax machines that have been modified to send slower, and lousy phone connections can drastically slow the transmission speed down.
How does fax confirmation work?
When the receiving fax machine sends a confirmation signal, the sending fax machine prints a confirmation page. As a backup, most fax machines keep logs of the time, date, number of pages, and success status of any fax transmissions.
Do you fax face up or face down?
If the icon has lines of text on the front of it then you should send a fax with the paper face up. If the text lines only appear on the folded corner, send the fax with the paper face down.
What does Fax number mean?
A fax number is just a phone number that has a fax machine (or fax service, fax server, computer with fax software, etc.) connected to it. Some fax machines have a phone that can be used to test the connectivity of the phone line or to make phone calls.
What is fax number?
A fax number is a phone number that can be used to contact a fax machine. It looks exactly like a regular phone number.
