IntranetFax Function

“The IntranetFax (Direct SMTP)”, hereafter called “the IntranetFax”, is a function that enables a direct InternetFax 
communication between MFPs without a mail server. Since there are some restrictions on this function, such as the 
necessity of including the IP address of the receiving MFP in its Email address, this function is suitable for InternetFax 
transmission within the Intranet.

IntranetFax compatible MFP -> IntranetFax compatible MFP

The IntranetFax function has the following characteristics:



You will not need to access a mail server when receiving IntranetFaxes because they are directly sent from the 
sending MFP to the receiving MFP.



You can clearly confirm on the sending MFP if the sent IntranetFax has been received because the transmission 
“finishes” upon reception by the receiving MFP. Transmission will be retried when the IntranetFax has not been 
received in cases such as when the power of the receiving MFP was not ON.



The Email address of the receiving MFP must include its IP address. For details, see 



 P.10 “Email Address Format”.



In the IntranetFax function, transmission is performed for a number of destinations, namely, it may take a longer time 
than transmission by the InternetFax through a mail server.



For e-STUDIO456 Series and e-STUDIO507 Series, the IntranetFax function is available only when the following 
options are installed:

- Scanner Kit 
- Printer/Scanner Kit



When the IntranetFax function is enabled, the onramp gateway, offramp gateway, network Fax and Address Book 
Viewer are disabled.



When an IntranetFax is being sent, SSL communication and SMTP authentication are not used. For details, see
