Cause/What to do
Cause:
You are not importing a certificate file in X509 format.
What to do:
For more information on the certificate, see the website of the certificate authority.
Cause:
The file you have imported is too large. The maximum file size is 5KB.
What to do:
If you select the correct file, the certificate might be corrupted or fabricated.
Cause:
The chain contained in the certificate is invalid.
What to do:
For more information on the certificate, see the website of the certificate authority.
Cause:
The certificate file in PKCS#12 format contains more than 3 CA certificates.
What to do:
Import each certificate as converting from PKCS#12 format to PEM format, or
import the certificate file in PKCS#12 format that contains up to 2 CA certificates.
Cause:
The certificate is out of date.
What to do:
❏
If the certificate is out of date, obtain and import the new certificate.
❏
If the certificate is not out of date, make sure the printer's date and time are set
correctly.
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 printer
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.
