Sharp BP-1360M/BP-1250M — 016-772
Sharp 016-772 means no DNS server address is configured. The guidance here is specific to BP-1360M/BP-1250M and the DNS/network operation.
Error meaning
No DNS server address is configured.
This interpretation is tied to the reviewed family/platform and subsystem. Do not reuse the code by itself on another printer family.

What usually causes it
- The printer has no usable DNS server address. Host names such as mail or scan servers cannot be resolved reliably until a DNS resolver is configured on the device or supplied by the network.
- The exact condition recorded for this code is: No DNS server address is configured.
- Open the normal network settings and verify that at least one DNS server address matches the network’s actual resolver. If the printer uses DHCP, confirm that DHCP is supplying DNS rather than replacing it with an unrelated public or stale address.
What to try
Check the condition this code actually names
Configure the correct DNS server address and retry the network operation.
Isolate the affected part of the workflow
Open the normal network settings and verify that at least one DNS server address matches the network’s actual resolver. If the printer uses DHCP, confirm that DHCP is supplying DNS rather than replacing it with an unrelated public or stale address.
Run a controlled confirmation test
After DNS is corrected, retry the same operation that used a host name. Do not also change SMTP credentials or destination paths during this test because the goal is to prove name resolution first.
After each corrective action
Retry the original operation that produced 016-772. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 016-772 returns despite a visible DNS address, record whether the printer received its network settings automatically or manually and whether an IP-address destination works where a host name fails.
When service may be needed
DNS changes should follow the local network design. Do not bypass managed network policy or enter arbitrary resolver addresses simply to suppress the code.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
