What usually causes it
- This group indicates that the device cannot connect to the SMTP server. The relevant checks are server address, network reachability, sender configuration, and the mail service itself—not the recipient mailbox contents.
- The exact condition recorded for this code is: The device cannot connect to the SMTP server.
- Verify the configured SMTP server name/address and ensure the mail service is reachable from the printer network. When a host name is used, confirm DNS; when an IP is used, confirm the correct server has not changed.
What to try
Check the condition this code actually names
Verify the SMTP server is running and the configured server address/From address are correct.
Isolate the affected part of the workflow
Verify the configured SMTP server name/address and ensure the mail service is reachable from the printer network. When a host name is used, confirm DNS; when an IP is used, confirm the correct server has not changed.
Run a controlled confirmation test
Resend a one-page email after the connection path is corrected. If the error changes to authentication or address validation, that is evidence that the server connection now succeeds.
After each corrective action
Retry the original operation that produced 2C65/2C66/2C69. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If the 2C65/2C66/2C69 group persists, note which exact subcode is displayed along with server name, port, and whether other devices can reach the same SMTP endpoint.
When service may be needed
Do not broadly open firewall rules or disable mail security. Network and mail administrators should correct the specific route or server configuration.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
