Kyocera 3101: Email send failed because source/destination
Kyocera 3101 means email send failed because source/destination authentication methods do not agree; verify SMTP/POP authentication configuration and retry. This guidance is specific to ECOSYS MA4000cifx/MA4000cix/MA3500cifx/MA3500cix platform and the SMTP / Email subsystem. Compare the configured SMTP authentication method and any POP-before-SMTP setting with the mail server’s.
Error meaning
Email send failed because source/destination authentication methods do not agree; verify SMTP/POP authentication configuration and retry.
This interpretation is tied to the reviewed family/platform and subsystem. Do not reuse the visible code by itself on another printer family.

What usually causes it
- 3101 is an email-send authentication-method mismatch. It is more specific than a generic server-unreachable error: the SMTP/POP authentication configuration on the source and destination sides does not agree.
- The exact reviewed condition is: Email send failed because source/destination authentication methods do not agree; verify SMTP/POP authentication configuration and retry.
- Compare the configured SMTP authentication method and any POP-before-SMTP setting with the mail server’s required method, user name, and port. Change only the mismatched authentication setting.
What to try
Check the condition this code actually names
Compare the configured SMTP authentication method and any POP-before-SMTP setting with the mail server’s required method, user name, and port. Change only the mismatched authentication setting.
Keep the test focused
Change only the setting, supply, paper path, or component named above. Leave unrelated network, driver, and service settings alone so the retest tells you something useful.
Run a controlled confirmation test
Send a one-page email test after correcting authentication. If the code changes to a connection, certificate, or recipient error, preserve that new code because the transaction advanced.
After each corrective action
Retry the original operation that produced 3101. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 3101 remains, record the authentication method selected on the printer and the method the mail server is configured to accept.
When service may be needed
Do not disable authentication or weaken mail security. Use an approved mail configuration or involve the mail administrator.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
