Digital Certificate Problem

Symptom
The LDAP-SSL/TLS
Communication setting and the
Upload Signed Certificate button
are not displayed.
The certificate import button is
disabled.
The certificate details button is
disabled.
The certificate cannot be imported. The time setting is incorrect.
016-404 is displayed when setting
the encryption of the optional hard
disk to Off.
016-404 is displayed when
formatting the optional hard disk.
Security is set to Off when setting
encryption of the optional hard disk
to Off.
Security is set to Off when
formatting the optional hard disk.
A certificate is deleted when setting
encryption of the optional hard disk
to Off.
A certificate is deleted when
formatting the optional hard disk.
Cause
The optional hard disk installed in
the printer is not encrypted.
SSL communication is disabled.
The certificate file is incorrect.
The browser is incorrect.
The optional hard disk is formatted
and the certificate data is deleted
when setting encryption of the
optional hard disk to Off. Since a
certificate is required and the
security function cannot be enabled
when restarting the device afterward,
016-404 is displayed and the security
setting must be initialized. The
cause is the same when formatting or
removing the optional hard disk.
The task is complete. Contact Dell.
(The toner cartridge
(C) you are using has
been damaged. Replace
it with a new one.)
Action
Confirm whether the optional hard disk is
connected correctly, and confirm whether Data
Encryption is enabled from the operator panel or
Dell Printer Configuration Web Tool.
Create a self-signed certificate and enable SSL.
Confirm validity period of the certificate as well as
the time setting of the device.
Confirm whether the password is correct.
Confirm whether the file type is PKCS#7/#12 or
x509CACert (extension: p7b/p12/pfx/cer/crt).
Confirm whether the attribute information (key
Usage/Extended key usage) of the certificate to be
imported is set correctly.
Use Internet Explorer.
After initializing, import the certificate and enable
the security settings again. The action is the same
when formatting the optional hard disk.
