Send a Fax in Real Time

When sending a fax, the machine scans the document into the memory before sending it. As soon as the telephone line is free, the machine starts dialling and sending. If you want to send an important document immediately without waiting for the machine to retrieve the scan from its memory, turn on [Real Time TX].
  • If the memory is full and you are sending a fax from the ADF, the machine sends the document in real time (even if [Real Time TX] is set to [Off]). If the memory is full, faxes from the scanner glass cannot be sent until you clear some of the memory.
  • In Real Time Transmission, the automatic redial feature does not work when using the scanner glass.
  • If [Real Time TX] is set to on, the option to scan 2-sided documents is not available.
  1. Load your document.
  2. Press [Fax]>[Options]>[Real Time TX].
  3. Press [On] or [Off].
  4. Press [OK]. (If the [OK] button is displayed.)
  5. Enter the fax number.
  6. Press [Fax Start].
