Updating HP LaserJet Pro 400MFP M425dn Printer Firmware to troubleshoot Scan to Email issues
A firmware update is recommended as part of the troubleshooting process when the Scan to Email feature is not working correctly. Firmware updates can provide bug fixes, security improvements, compatibility updates, and fixes related to network services.
Important: A firmware update does not guarantee that a Scan to Email problem will be resolved. Scan to Email also depends on the SMTP server configuration, authentication method, network connectivity, and supported security protocols.
