What usually causes it
- Support code 3415 means the printer could not communicate with the configured incoming POP3 mail server. This is separate from an outgoing SMTP failure.
- The exact reviewed condition is: Communication with the incoming POP3 mail server failed; verify server address and port, then server condition.
- Check the POP3 server address and port against the mail provider’s current settings and confirm the server is available from the printer network.
What to try
Check the condition this code actually names
Check the POP3 server address and port against the mail provider’s current settings and confirm the server is available from the printer network.
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
Retry the mail-related operation after correcting only the POP3 address/port. Avoid changing outgoing SMTP credentials during this confirmation.
After each corrective action
Retry the original operation that produced 3415. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 3415 remains, record whether the server is entered by host name or IP and whether DNS resolution is working for the printer.
When service may be needed
Do not disable network security broadly to make POP3 reachable. Have the mail/network administrator correct the specific service path.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
