Konica Minolta IEEE 802.1X Error 2
IEEE 802.1X settings do not match the network's authentication requirements.
Error meaning
IEEE 802.1X setting error.
This meaning is tied to the reviewed family/platform and subsystem below; do not reuse the number or wording by itself on a different printer family or protocol.
Applies to
bizhub C287/C227
- bizhub C287
- bizhub C227
Common formatting
These are formatting/lookup aliases for this reviewed condition, not separate error pages.
- 2
- ieee8021x-2
What usually causes it
- 802.1X is enabled on the printer but the configured authentication settings are incomplete or inconsistent.
- The network expects a different EAP mode, credential type, or certificate setup than the device is configured to use.
- A recently changed switch, wireless, or RADIUS policy no longer matches the saved printer configuration.
What to try
Confirm this is the 802.1X network error
Use this meaning only when the C287/C227 reports code 2 in the IEEE 802.1X/LAN context. Do not apply it to an unrelated numeric code 2.
Compare the printer's 802.1X profile with the network policy
Have the network administrator verify whether 802.1X should be enabled and which EAP method, identity, and certificate options the network requires.
Check for a recent network-policy change
If the printer worked before, compare the saved 802.1X settings with any recent switch, wireless-controller, or RADIUS changes.
Retry authentication without weakening security
Correct the mismatched setting, reconnect the network interface, and retry. Do not disable certificate checks or 802.1X simply to make the error disappear.
After each corrective action
Retry the same operation that produced 2. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If code 2 returns after the profile matches the network policy, capture the configured EAP method and ask the network administrator to review the authentication logs for this device.
When service may be needed
This is normally a network-authentication configuration problem. Printer disassembly is not indicated; escalate to the network administrator or Konica Minolta support if the settings are correct but authentication still fails.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
