What usually causes it
- The printer has no primary SMTP gateway/server configured.
- Email setup may have been cleared during deployment or configuration changes.
- The message can appear even if ordinary printing works, because it belongs to the email function.
What to try
Decide whether the printer's email function is actually used
If Scan to Email is required, obtain the organization's approved SMTP settings.
Configure the SMTP gateway/server
Use the Lexmark control panel or Embedded Web Server with the approved server, port, authentication, and security settings.
Keep authentication and TLS requirements intact
Do not use an open relay or disable security to silence the message.
Test the email function
Send a small test scan/message and confirm 72.01 clears.
After each corrective action
Retry the same operation that produced 72.01. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If 72.01 remains after a valid SMTP server is saved, verify that the settings were applied to the correct device and that administration policy is not overwriting them.
When service may be needed
Lexmark also documents an option to suppress the intervention message when email is intentionally unused, but that is not a fix for a required Scan to Email workflow.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
