Hi yglazer1
Please keep in mind we will not know specific network information you will need to enter such as port numbers and so on. You will need to obtain this information from your IT Admin as they will have this information available. Also note that scan to email is designed to work with an on site email server such as an MS Exchange server or a Domino server and not offsite email servers such as Yahoo or G-Mail.
If your imageCLASS MF249 is connected to your network and you have an on site email server, you should be able to send scans via e-mail. Please note that we recommend that network settings and settings to send scanned documents be performed by the network administrator. The information for setting the imageCLASS MF249 to be able to send scanned documents is available when you click HERE
