Messages Cause/What to do
Cannot use the Server Certicates that
include more than three CA
certicates.
Cause:
The certicate le in PKCS#12 format contains more than 3 CA certicates.
What to do:
Import each certicate as converting from PKCS#12 format to PEM format, or
import the
certicate
le
in PKCS#12 format that contains up to 2 CA
certicates.
The certicate has expired. Check if the
certicate
is valid, or check the date
and time on your printer.
Cause:
The certicate is out of date.
What to do:
❏ If the
certicate
is out of date, obtain and import the new
certicate.
❏ If the certicate is not out of date, make sure the printer's date and time are set
correctly.
Private key is required.
Cause:
There is no paired private key with the certicate.
What to do:
❏ If the
certicate
is the PEM/DER format and it is obtained from a CSR using a
computer, specify the private key le.
❏ If the certicate is the PKCS#12 format and it is obtained from a CSR using a
computer, create a le that contains the private key.
Cause:
You have re-imported the PEM/DER certicate obtained from a CSR using Web
Cong.
What to do:
If the
certicate
is the PEM/DER format and it is obtained from a CSR using Web
Cong, you can only import it once.
Setup failed.
Cause:
Cannot nish the conguration because the communication between the printer
and computer failed or the le cannot be read by some errors.
What to do:
After checking the specied le and communication, import the le again.

There is no backup le for the CA-signed certicate.
If you have the backup le, import the certicate again.

Create a CSR and obtain a new certicate.
