What you will see

The e-mail function of Advanced E-mail Settings, E-mail Size Limiter, or Scan to Network Premium app fails, and may cause the following scenarios:

Application Observed Behavior
Advanced E-mail Settings

The following error message displays on the control panel: “E-mail Server Configuration Error. Please Contact your System Administrator.

Or e-mail may not be sent successfully, and no error message is displayed on the control panel.

Important! This issue ONLY occurs when the AccuRead OCR app is installed, and OCR is turned ON in the Advanced E-mail Settings’ configure page.

E-mail Size Limiter

Print an error log “Connection Failure -7. No e-mail is received on the destination address.

Or e-mail may not be sent successfully, and no error message is displayed on the control panel.

Scan to Network Premium
E-mail is not sent successfully, and no error message is displayed on the control panel.

This happens when the “Primary SMTP Gateway Port” is set to 465 or 587, and “Use SSL/TLS” is set to Required under the printer’s embedded web server (EWS) > Settings > E-mail/FTP Settings > SMTP Setup.
