7.5.4.3 A certificate cannot be created. (C330dn/C530dn only)
When a certificate cannot be created, the following causes are probable.
Take an appropriate measure by referring to the following sections.
* Not all the required entry fields are filled in.
-> Refer to section “7.5.4.3.1 Not all the required entry fields are filled in.”
* The printer is printing.
-> Refer to section “7.5.4.3.2 The printer is printing.”
7.5.4.3.1 Not all the required entry fields are filled in.
If every required entry field is filled in, a certificate cannot be created.
To create a certificate, the followings must be filled in: CommonName, Organization, Locality,
State/Province, Country/Region. (Entry into Organizational Unit may be skipped.)
Solution: Enter appropriate values into all of the required entry fields, and
execute creation of a certificate. For details of the required entry fields
and how to create certificates, refer to the User’s Manual (Advanced).
7.5.4.3.2 The printer is printing.
No certificate can be created during printing. (Print operation has priority.)
Solution: It is required to keep the printer not to perform any operation (such as
printing) until the whole operation from creating a certificate, a self-
signed certification and a CSR of a certificate of a certifying authority,
to installing a certificate is completed (completion of creation of a self-
signed certification and a CSR, and completion of installation of a
certificate).
7.5.4.4 A certificate cannot be installed. (C330dn/C530dn only)
When installation of a certificate fails, the following causes are probable.
Take an appropriate measure by referring to the following sections.
* The user has changed the IP address of the printer to an IP address that is
different from the IP address used during creation of a CSR.
-> Refer to section “7.5.4.4.1 The printer IP address has been changed.”
* The network card is initialized while the user is applying for issuance of a
certificate to a certifying authority (i.e., while waiting for installation of a
certificate).
-> Refer to section “7.5.4.4.2 The network card has been initialized.”
* “Deletion of CSR” was executed while the user is applying for issuance of
a certificate to a certifying authority (i.e., while waiting for installation of a
certificate).
-> Refer to section “7.5.4.4.3 A CSR has been deleted.”
* An intermediate certificate is installed.
-> Refer to section “7.5.4.4.4 Install an intermediate certificate.
7.5.4.4.1 The printer IP address has been changed.
If the printer IP address is different from the IP address used during creation of a CSR in
trying to install a certificate, an error occurs and installation of a certificate is not performed.
If a change was made to the setting of printer IP address only, no error will occur after the IP
address is changed to the original one.
Solution: Reset the IP address of the printer to the IP address used during
creation of a CSR, and then install a certificate.
Note! Do not change any printer setting while a creation process of a certificate of
a certifying authority is in progress (during a period from creation of a CSR
to installation of a certificate). If any printer setting is changed, the issued
certificate becomes invalid necessitating resetting from the beginning. If printer
setting is changed after a certificate is obtained, Security warning is displayed
on the Web browser.
If the IP address of the printer is changed, the certificate becomes invalid. (Pay
certificates of certifying authorities may require some charge for reissuance.
For details, contact certifying authorities.)
