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 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. See "Generating a Key Pair and Server Certificate," or "Registering a Key Pair File and Server Certificate File Installed from a Computer" to register a key pair.
<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.
Set all settings for [Restrict Receiving for Each Function] in [Device Information Delivery Settings] to 'On.' For details, see "Specifying Device Information Delivery Settings."
<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.
Set all settings for [Restrict Receiving for Each Function] in [Device Information Delivery Settings] to 'On.' For details, see "Specifying Device Information Delivery Settings."
<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.
NOTE
For instructions on how to confirm whether the key pair you are using is corrupted, see "Editing Key Pairs and Server Certificates."
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.
NOTE
For instructions on how to confirm whether the key pair you are using is corrupted, see "Editing Key Pairs and Server Certificates."
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 "Installing a Key Pair File and Certificate File.") 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.
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 "Setting/Confirming a Key Pair and Device Certificate." to confirm the device certificate settings.
