7.8.4 Can't Install the Certificate
If the installation of the certificate fails, you may have the following situations:
Refer to the applicable section and correct the problem:
• The user has changed the printer's IP address to a different IP address from the one
used at the time when "CSR was created".
→ Refer to 7.8.4.1 The printer's IP address has been changed.
• The user executed Initialize Network Card in the state that he had applied to the
certification authority for the issuance of the certificate (waiting for the installation of the
certificate).
→ Refer to 7.8.4.2 Executed Initialize Network Card.
• The user executed Delete CSR in the state that he had applied to the certification
authority for the issuance of the certificate (waiting for the installation of the certificate).
→ Refer to 7.8.4.3 Executed Delete CSR.
• Intermediate certificate has been installed
→ Refer to 7.8.4.4 Want to install an intermediate certificate.
7.8.4.1 Printer's IPP address has been changed
Installation of the certificate will fail if the printer's IP address is different from the "IP address when
CSR was created". (An error will result.)
If the setting that has been changed is only the "Printer's IP address", the error ceases to occur if you
return the IP address to the original one.
What to do: Reset the printer's IP address to the "IP address when CSR was created" and install the
certificate again.
Caution:
Do not change the printer settings during the procedure to create the certificate
signed by a certification authority (from creating CSR to installing the certificate).
If you do so, the certificate that has been issued becomes invalid, and you'll have
to perform the procedure to create a certificate all over again. If you change the
printer settings after you have obtained the certificate, "Security Alert" will be dis-
played on the Web browser. If the printer's IP address is changed, the certificate
becomes invalid. (In case of a CA-signed certificate with a fee, an extra fee may
be charged for creating the certificate again.) For the detail, contact the certification
authority.
7.8.4.2 Executed Initialize Network Card
If you initialize Network Card (which sets factory default) during the procedure to create the certificate
signed by a certification authority (from creating CSR to installing the certificate), the setting information
of the certificate will be lost. The information that has been deleted will never be recovered. (Even if
you enter the same information as before, you will not be able to create the same certificate.)
What to do: Perform the procedure to create the certificate all over again. (The certificate that has been
applied to the Certification Authority is already void.)
7.8.4.3 Executed Delete CSR
If you delete CSR (delete the certificate) during the procedure to create the certificate signed by a
certification authority (from creating CSR to installing the certificate), the setting information of the
certificate will be lost. The information that has been deleted will never be recovered. (Even if you enter
the same information as before, you will not be able to create the same certificate.)
What to do: Perform the procedure to create the certificate all over again. (The certificate that has been
applied to the certification authority is already void.)
