What usually causes it
- A certificate field, key usage, algorithm, or other parameter does not meet the printer's authentication requirements.
- The wrong client or CA certificate was imported for the selected EAP method.
- A renewed certificate uses parameters that differ from the previously working certificate.
What to try
Identify which certificate the active EAP profile uses
Separate client-certificate, CA, and server-certificate roles before changing anything.
Check certificate purpose and validity
Have the administrator confirm the certificate is intended for the selected authentication role and has acceptable key usage, algorithm, dates, and chain.
Compare with the last known working certificate
If the problem followed renewal, compare the old and new certificate parameters rather than changing unrelated Wi-Fi settings.
Install only the correct certificate and retry
Replace or reconfigure the invalid certificate parameter while keeping 802.1X verification enabled.
After each corrective action
Retry the same operation that produced 35. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If code 35 returns with a certificate that appears valid for the intended role, collect the certificate metadata and printer firmware version for administrator/vendor review.
When service may be needed
Persistent invalid-certificate-parameter errors should be escalated to the network/security administrator or Konica Minolta support. Do not use untrusted certificates or disable 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.
