Even if SP 1-012-001 = 0 the most recently used scan destination can still be cleared by the
Scanner Auto Reset timer. If the Scanner Auto Reset timer is shorter than the System Auto Reset
timer, then the most recently used scan destination will be cleared when the Scanner Auto Reset
timer elapses.
The Setting of SMTP Authentication in Scan to Email
Scan to Email fails with the error message "Transmission has failed ". The SMTP username and password
are correct. How can I make Scan to Email pass ?
Change SP 5-860-022 "SMTP Auth. From Field Replacement" to On. By doing this, Scan to Email will
pass the SMTP authentication.
• Using this option to solve the above problem, the device email address will appear in the email's
"From" field. The email address of the user who sent the email will appear in the "Reply-to" field.
Explanation
This is an SMTP authentication issue that aborts transmission of an already started Scan to Email.
Currently this has only been reproduced using MS-Exchange server.
MS-Exchange requires that all of the following match:
1. The sender's address in the "MAIL FROM" field. This is also known as the "envelope sender" or
"MIME sender". It is an SMTP command sent at the beginning of the email transmission process.
2. The sender's address in the mail header "From:" field. This appears as "From" in email clients. It is a
part of the email itself.
3. The email address corresponding to the SMTP username used to login into the SMTP server.
When the MFP logins into the SMTP server, the email address of the username 3) will be compared to
1) and 2). If these comparisons fail, authentication will also fail. Exchange server will stop the
transmission procedure, and the "Transmission has failed" message will be returned to the sender.
Typical Example
NG case:
SP5-860-022 is Off:
1. The "MAIL FROM" field = device (Fig.1 )
2. The mail header "From:" field = user (Fig.2 )
3. The SMTP username = device (Fig.1 )
When the SMTP server compares 2) and 3) the Exchange Server will stop the transmission procedure.
OK case:
SP5-860 can be used to make the values in the above example, match.
