Solutions

Quick Diagnosis

Error 016-753 usually pops up after password changes or security policy updates. If it worked previously, check port settings and SSL/TLS certificates.

Step-by-step Solution

  1. Access the printer web UI (CWIS).
  2. Navigate to SMTP settings and re-validate server address, port, and auth info.
  3. Generate an App Password if using Gmail/Outlook, as standard passwords are often rejected.
  4. Test the connection using the built-in CWIS tool.

Prevention and Maintenance

Always use application-specific passwords for office devices and maintain an updated log of your server parameters.

When to call a technician

If your email provider confirms settings are correct but the printer still rejects the connection, server firewall IP restrictions might be the culprit.
