Encrypted SSL Data Communication Problems and Remedies

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

<The default key is not set. Check the [Key and Certificate List] settings in the Certificate Settings> is displayed when SSL is set.

<Cannot delete the default key when SSL is On, or when the [Restrict Receiving for Each Function] setting in Device Information Delivery is Off. Check the SSL or Device Information Delivery setting.> is displayed when you try to erase a key pair.

<Cannot change settings because the selected key is being used. Check the SSL or Device Information Delivery setting.> 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 the 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 "Key Pair and Server Certificate Settings for Encrypted SSL Communication."

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 Device Information Delivery Settings.
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 Device Information Delivery Settings to 'On.'

<Cannot change settings because the selected key is being used. Check the SSL or Device Information Delivery setting.> 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 Device Information Delivery Settings.
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 Device Information Delivery Settings to 'On.'

<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.

Cause1

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.

Cause2

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.

Cause3

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 "Registering a Key Pair File and Server Certificate File Installed from a Computer.") Then, register the installed files on the control panel of the machine.

NOTE
For instructions on how to confirm whether the key pair you are using is corrupted, see "Editing Key Pairs and Server Certificates."

<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.

Cause1	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.
Cause2	Access to the device certificate was denied when sending a PDF or XPS file with a device signature.
Remedy	See "Confirming a Key Pair and Device Certificate" to confirm the device certificate settings.
