3.9 Printing Using E-mail - E-mail Print -  75
Precautions When Using the E-mail Print Feature
Security Precautions
E-mail uses the Internet, a network connecting computers around the world, as its 
transmission medium. So, exchanging e-mails involves security risks, such as information 
leakage and tampering.
When exchanging important or confidential information, we recommend you to use a 
method other than e-mail that guarantees security. And to prevent unwanted e-mails, we 
encourage you not to give out your e-mail address unless necessary.
Setting the Access-Permitted Domains
The printer can be programmed to receive e-mails only from particular domains.
For more information, refer to the online help provided for CentreWare Internet Services.
Precautions When Connecting the Printer with an Internet Provider
• If your Internet provider does not bill you a flat rate, or if you do not have full-time access 
to the Internet, you will be charged every time the printer retrieves data from the e-mail 
server. 
• Make sure to connect the printer in an IP masqueraded environment. This feature may not 
function properly when the printer is connected to the Internet with a global IP address 
assigned. 
• When enabling POP access, make sure to create an e-mail account specific for the printer. 
Using a shared e-mail account can cause problems.
• When the circuit speed of the Internet is slow, it may take time to receive large data such 
as graphics. 
• When connecting the printer to an Internet environment where MTA is running in a private 
segment, configure the settings according to your operating needs.
