Difficulty: HardMultifunction Devices and Printer Configuration

An enterprise environment requires a newly added multifunction device (MFD) to route scanned documents directly to internal email recipients. During setup via the Embedded Web Server (EWS), scan delivery attempts fail with a connection timeout error. Diagnostic logs reveal the device is attempting unencrypted transmission over port 25 without a network gateway specified, whereas the enterprise mail server mandates encrypted transport and proper subnetwork routing. Which configuration changes must be made on the MFD to restore Scan-to-Email functionality?

  1. Configure the SMTP server settings to use port 587 with TLS encryption, enter authentication credentials, and define the correct default gateway IP address.Answer
  2. B
    Configure the HTTP server settings to use port 443 with SSL encryption, enter administrative credentials, and set the primary DNS address as the default gateway.
  3. C
    Enable the DHCP server role on the MFD to lease dynamic mail delivery ports and reconfigure the network DNS service to allocate IP addresses to outgoing messages.
  4. D
    Set up POP3 protocol settings on port 110 on the MFD so it can download recipient mail routing tables prior to sending scan attachments.

Answer

Configure the SMTP server settings to use port 587 with TLS encryption, enter authentication credentials, and define the correct default gateway IP address.
To resolve Scan-to-Email failures where the mail server enforces encryption and authenticates senders, the MFD must be configured to use SMTP with TLS on port 587 (or port 465) along with valid authentication credentials. Adding the default gateway enables the MFD to route network packets to mail servers located outside the local IP subnet.

Step-by-Step Solution

1
Identify the required network service for sending scanned documents to email endpoints.
Scan-to-Email relies on Simple Mail Transfer Protocol (SMTP).
MFDs act as email clients submitting messages to an SMTP relay or mail server.
2
Determine the secure transport port and encryption method required by modern mail servers.
SMTP submission uses port 587 with TLS (or port 465 with implicit SSL/TLS), replacing legacy unencrypted port 25.
Enterprise mail infrastructure enforces encrypted transmission and user authentication to prevent unauthorized relaying.
3
Verify network layer routing parameters in the MFD configuration.
Assigning a valid default gateway IP address allows the MFD to route packets beyond its local subnet.
Without a default gateway, traffic destined for off-subnet mail servers cannot be routed.
