What usually causes it
- The server certificate is not trusted by the CA material installed on the printer.
- The printer's date/time is wrong, making an otherwise valid certificate appear invalid.
- The certificate name, chain, or verification settings do not match the enterprise 802.1X policy.
What to try
Check the printer's date and time first
Certificate validity depends on time. Correct a clearly wrong clock before replacing certificates.
Verify the trusted CA path
Confirm the CA certificate required to validate the RADIUS/EAP server is present and is the one your network administrator expects.
Compare the server certificate identity with policy
Check whether the network requires a particular server name or certificate identity and whether that identity recently changed.
Retry without disabling certificate verification
Correct trust, time, or identity settings and reconnect. Disabling server-certificate checks would weaken the network's authentication protection.
After each corrective action
Retry the same operation that produced 10. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If code 10 remains after time and trust configuration are correct, the network administrator should compare the server certificate chain and the printer's configured verification rules.
When service may be needed
The fault is in certificate trust or authentication configuration, not a user-serviceable mechanical part. Escalate with the server certificate details rather than bypassing verification.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
