The following is a list of self-diagnostic error messages, along with their possible causes and remedies.

Cause	The document could not be sent because there was insufficient memory available.
Remedy 1	Lower the resolution or divide the document into two or more parts, and then try sending the document again.
Remedy 2	Delete documents with errors to make more memory available. (See "Checking the Detailed Information for/Deleting a Document in the Memory RX Inbox.")
Remedy 3	If this problem occurs frequently, contact your local authorized Canon dealer.

Cause	The specified server settings are incorrect, or the server is not turned ON. Alternatively, the machine's TCP/IP resources may be low.
Remedy	Wait for a while, and then try browsing again. If there is still no response from the server, try selecting another server.

Cause	You have exceeded the maximum number of subdirectory levels allowed.
Remedy	You cannot specify the current subdirectory. Specify another destination.

Cause	If <Login Information> in Register LDAP Server is set to [Use (security auth.)] for the LDAP server, the machine will not be able to determine the host name.
Remedy 1	Check the DNS settings. (See "Protocol Settings.")
Remedy 2	Check whether the DNS data settings are correct on the DNS server.

Cause	The machine cannot connect to the specified IP address/port.
Remedy 1	Check the Server Address and Port Number in Register LDAP Server. (See "Registering an LDAP Server.")
Remedy 2	Check whether the LDAP server is operating normally.
Remedy 3	If <Login Information> is set to [Use (Security Auth.)] for the LDAP server, check whether UDP (User Datagram Protocol) packages are blocked by the filter.

Cause 1	The user name or password is incorrect when setting Login Information for the LDAP server to [Use] or [Use (Security Auth.)].
Remedy	Check the user name and password in Register LDAP Server. (See "Registering an LDAP Server.")
Cause 2	The domain name is incorrect when setting Login Information for the LDAP server to [Use (Security Auth.)].
Remedy	Check the domain name in Register LDAP Server. Check the user name and password. (See "Registering an LDAP Server.")

Cause	The search could not be completed within the time specified under <Search Timeout>.
Remedy	Increase the time setting for Search Timeout in Register LDAP Server. (See "Registering an LDAP Server.")

Cause	The number of addresses that meet the search criteria exceeds the specified maximum number of addresses to search.
Remedy 1	Narrow down the search criteria, and then search again.

Cause 1	"\" is used in the search criteria.
Remedy	Remove "\" from the search criteria, and then search again.
Cause 2	The combination of characters used in the search do not constitute acceptable search criteria. There is an unequal number of "("and")". "*" is not placed within "( )".
Remedy	Make sure that the characters for the search criteria form a legitimate combination, and then search again.
Cause 3	Characters other than ASCII Code (0x20-0x7E) are being used, when [LDAP Server Version and Character Code] is set to [ver.2 (JIS)].
Remedy	Omit characters that cannot be used, and then search again.

Cause	Although [ver. 3] is selected as the server LDAP version number in Register LDAP Server, the LDAP server is running on version 2.
Remedy	Set the Server LDAP version and character code to [ver. 2] in Register LDAP Server. (See "Registering an LDAP Server.")
