Saves received faxes as PDF files to an external memory device connected to the printer.
Received documents are saved in the printer's memory temporarily before the documents are saved in the memory device connected to the printer. Because a memory full error disables sending and receiving faxes, keep the memory device connected to the printer.
Forwards received faxes to another fax machine, or forwards them as PDF files to a shared folder on a network or to an email address. Forwarded faxes are deleted from the printer. First add the forwarding destination to the contacts list. To forward to an email address, you also need to configure the email server settings.
Destination: You can select a forwarding destination from the contacts list you added in advance.
If you have selected a shared folder on a network or an email address as the forwarding destination, we recommend that you test if you can send a scanned image to the destination in the scan mode.
