If you want to speak to the recipient before sending a fax, or if the recipient does not have a fax machine that can receive faxes automatically, send a fax manually after speaking to the recipient on the telephone to check whether the recipient can receive faxes.


  • It may be possible that faxes will reach unintended recipients due to the misdialing or incorrect registration of fax/telephone numbers. When you send important documents, it is recommended that you send them after speaking on the telephone. See below for the procedure to send a fax manually.

  • With manual transmission, you cannot use the platen glass to load documents. Load the documents in the ADF.

    When loading document on the platen glass, send a fax with automatic transmission.
