What usually causes it
- The printer reached the SMTP service but could not authenticate with the configured mail account. The failure is therefore later in the connection sequence than a server-not-found or network error.
- The exact condition recorded for this code is: SMTP authentication failed.
- Verify the SMTP user name, password, authentication method, and mail port against the account’s current settings. If the password was recently changed, update the stored printer credential through the normal administrator interface.
What to try
Check the condition this code actually names
Verify the SMTP login/password and, when SSL is used, the configured mail port.
Isolate the affected part of the workflow
Verify the SMTP user name, password, authentication method, and mail port against the account’s current settings. If the password was recently changed, update the stored printer credential through the normal administrator interface.
Run a controlled confirmation test
Retry a small email after changing only the authentication settings. If login succeeds but another mail error appears, preserve that new code because it identifies the next stage of the transaction.
After each corrective action
Retry the original operation that produced 2C71. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 2C71 persists, have the mail administrator check whether the account is locked, disabled, subject to an application-password requirement, or using an authentication method the device does not support.
When service may be needed
Do not disable mail authentication or share credentials broadly to work around the code. Use an approved service account and supported authentication method.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
