Encrypted SSL Data Communication Problems and Remedies

This section describes how to resolve encrypted SSL data communication problems.

For explanations of messages that are not listed here, see "List of Error Messages."

<The Default Key is not set. Check the Key and Certificate List settings in Certificate Settings.> is displayed when SSL is set.

<Cannot delete the default key because it is in use by SSL or other settings. Check the settings.> is displayed when you try to erase a key pair.

<Cannot change settings because the selected key is being used.> is displayed when you try to change the default key.

<Cannot register because the algorithm of this key is not supported.> is displayed when you try to register a key pair file.

You cannot use encrypted SSL communication for IPP printing, email/I-fax, the Remote UI, MEAP functions via a web browser, and device information delivery, or confirm Department IDs and passwords even after you have turned SSL on.

<Certificate Exp. Date Error> is displayed.

<Digital Sig. Cert. Access Err> is displayed.

<The Default Key is not set. Check the Key and Certificate List settings in Certificate Settings.> is displayed when SSL is set.
Cause

The key pair or server certificate to use has not been registered.
Remedy

It is necessary to register a key pair and server certificate in order to perform encrypted SSL communication. For instructions on how to register a key pair, see "Generating a Key Pair and Server Certificate" and "Registering a Key Pair File and Server Certificate File Installed from a Computer."

<Cannot delete the default key because it is in use by SSL or other settings. Check the settings.> is displayed when you try to erase a key pair.
Cause

The key you are trying to erase is currently being used for encrypted SSL communication or used for the Restrict Receiving for Each Function mode in the device information delivery.
Remedy

Cancel all SSL settings and encrypted SSL communication. See "Specifying Device Information Delivery Settings," to set all settings for the Restrict Receiving for Each Function mode in the device information delivery.

<Cannot change settings because the selected key is being used.> is displayed when you try to change the default key.
Cause

The key you are trying to erase is currently being used for encrypted SSL communication or used for the Restrict Receiving for Each Function mode in the device information delivery.
Remedy

Cancel all SSL settings and encrypted SSL communication. See "Specifying Device Information Delivery Settings," to set all settings for the Restrict Receiving for Each Function mode in the device information delivery.

<Cannot register because the algorithm of this key is not supported.> is displayed when you try to register a key pair file.
Cause

You are trying to register a key pair file which uses the DSA algorithm.
Remedy

Register a key pair file which uses the RSA algorithm.

You cannot use encrypted SSL communication for IPP printing, email/I-fax, the Remote UI, MEAP functions via a web browser, and device information delivery, or confirm Department IDs and passwords even after you have turned SSL on.
Cause 1

The generated key pair or server certificate is corrupted.
Remedy

After erasing the key pair you are using, generate a key pair and server certificate.
Cause 2

The preinstalled default key pair or server certificate is corrupted.
Remedy

After erasing the key pair you are using, generate a key pair and server certificate.
Cause 3

The registered key pair file or server certificate file is corrupted.
Remedy

After erasing the key pair you are using, install the key pair file and server certificate file created on your computer using the Remote UI (See "Remote UI."). Then, register the installed files on the control panel of the machine.

  • For instructions on how to confirm whether the key pair you are using is corrupted, see "Editing Key Pairs and Server Certificates" and "Confirming a Key Pair and Device Certificate."

<Certificate Exp. Date Error> is displayed.
Cause

The certificate has expired.
Remedy

Confirm the expiration date for the certificate.

<Digital Sig. Cert. Access Err> is displayed.
Cause 1

Access to the user certificate was denied when sending a PDF or XPS file with a user signature.
Remedy

See "Confirming a Key Pair and User Certificate" to confirm the user certificate settings.
Cause 2

Access to the device certificate was denied when sending a PDF or XPS file with a device signature.
Remedy

See "Editing Key Pairs and Server Certificates" and "Confirming a Key Pair and Device Certificate" to confirm the device certificate settings.
