Points to Note When Sending E-mails
Security Issues
E-mails are sent via the Internet, connecting computers from all 
over the world. As a result, precautions must be taken relating to 
security issues such that information is not easily seen or altered 
by third parties.
Therefore, we recommend that you use methods to ensure that 
important information is secured. You are also advised not to 
reveal the e-mail address of this printer to third parties to avoid 
receiving spam.
Caution Regarding Internet Provider and E-mail Features
• In the case where a flat-rate contract with the Internet 
provider exists and the user is not always connected to the 
network, a telephone charge will be incurred every time this 
printer retrieves data regularly from the mail server.
• Connect the printer to an private IP address. Functionality of 
this printer is not guaranteed when it is assigned public IP 
addresses.
• When receiving e-mails via POP, always apply an exclusive 
e-mail account for the printer. Using a common e-mail 
account shared with other users will result in errors.
• When the internet connection speed is slow, it takes time to 
receive large amounts of data such as image data.
• There are also providers that allow reception of e-mails via 
SMTP. Detailed adjustments with the provider are required in 
such cases.
• When setting up the e-mail configuration in an environment 
where MTA support is set up in private segments, match the 
operating configuration.
