It will be best if you review the instructions for configuring Scan To Email:
Note, will need the following information:
SMTP server address
Hint, search google for SMTP email settings for [your mail service provider] example, gmail, office365, etc.
You can configure the settings for the printer using the steps in the link provided HERE. The information will vary based on which email service you have. In this situation, I would suggest contacting support at 1-800-652-2666, our agents would be able to walk you through the whole process and test the scanning.
