Konica Minolta IEEE 802.1X Error 14
PEAP started, but the printer and server could not agree on the inner phase-2 authentication method.
Error meaning
PEAP phase-2 method negotiation failed.
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.

What usually causes it
- The printer's PEAP phase-2 method does not match the method allowed by the RADIUS policy.
- The enterprise network changed its inner authentication policy while the printer retained an older PEAP profile.
- The selected EAP/PEAP combination is valid in general but not permitted for this printer account or WLAN.
What to try
Confirm the outer method is PEAP
Use this code specifically for the PEAP phase-2 negotiation failure; do not treat it as a generic password error.
Ask which inner method the RADIUS policy requires
Have the administrator identify the permitted phase-2 method for printers on this network.
Match the printer's phase-2 setting
Update the inner authentication choice so it matches the network policy, while leaving unrelated wireless and certificate settings unchanged.
Retry and inspect the RADIUS negotiation if needed
Reconnect once. If it still fails, the server log should show which phase-2 methods were offered and rejected.
After each corrective action
Retry the same operation that produced 14. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If code 14 returns with the expected PEAP inner method configured, the administrator should verify the RADIUS policy applied to this device, SSID, or switch port.
When service may be needed
No internal printer service is normally required. Treat persistent code 14 as an enterprise authentication-policy issue and avoid loosening security to force a connection.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
