Cause:
There is no paired private key with the certificate.
What to do:
❏ If the certificate is the PEM/DER format and it is obtained from a CSR using a
computer, specify the private key file.
❏ If the certificate is the PKCS#12 format and it is obtained from a CSR using a
computer, create a file that contains the private key.
Cause:
You have re-imported the PEM/DER certificate obtained from a CSR using Web
Config.
What to do:
If the certificate is the PEM/DER format and it is obtained from a CSR using Web
Config, you can only import it once.
Cause:
Cannot finish the configuration because the communication between the scanner
and computer failed or the file cannot be read by some errors.
What to do:
After checking the specified file and communication, import the file again.
