It is common for companies to have an email size limitation set on their mail servers. This setting enforces respect of the company’s email size policy.

When the Email Size Limit is set, you may be unable to send some documents.  NOTE:  An email attachment is a larger file than an original file. 

The Email Size Limit is set to 5000 KB.  A 4000 KB file is being emailed.

Step	Action
1	Scan the original document into the MFP.
2	The MFP will convert the document from binary data to Base64 Data.  NOTE:  The conversion adds approximately 33% more information to the document.
3	The Base64 data is sent to the mail server as a 5320 KB file.
4	The mail server rejects the document as it is larger than the Email Size Limit.
5	The MFP receives the document back from the mail server.
6	The MFP will convert the document back to binary data and the user will never see the file size increase.

Make sure the file size of the original document is less than 67% of the Email Size Limit.  NOTE:  If you are not sure of the Email Size Limit, please
contact your network administrator.
