Sharp BP-1360M/BP-1250M — 016-764
Sharp 016-764 means the device cannot connect to the SMTP server. The guidance here is specific to BP-1360M/BP-1250M and the SMTP/email operation.
Error meaning
The device cannot connect to the SMTP server.
This interpretation is tied to the reviewed family/platform and subsystem. Do not reuse the code by itself on another printer family.

- 016-764
What usually causes it
- The device cannot establish a connection to the configured SMTP server. The relevant path is printer-to-mail-server reachability; changing recipient addresses will not help if the server itself cannot be reached.
- The exact condition recorded for this code is: The device cannot connect to the SMTP server.
- Verify the SMTP host name or IP address and the configured mail port against the administrator’s current mail-server settings. If a host name is used, confirm that the printer also has working DNS configuration.
What to try
Check the condition this code actually names
Verify the SMTP server address and reachability, then retry the same email send.
Isolate the affected part of the workflow
Verify the SMTP host name or IP address and the configured mail port against the administrator’s current mail-server settings. If a host name is used, confirm that the printer also has working DNS configuration.
Run a controlled confirmation test
After correcting only the server address, port, or network reachability issue, resend the same small scan-to-email job. A connection attempt that advances to authentication is useful evidence that the network path is fixed.
After each corrective action
Retry the original operation that produced 016-764. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 016-764 persists, record whether the server is specified by name or IP and whether other devices on the same network can reach that mail service. That separates name-resolution problems from blocked or unavailable SMTP service.
When service may be needed
Do not weaken firewall or mail-server security broadly to clear this code. Network or mail administrators should make the smallest required server/port correction.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
