■ Specifications Related to Address Books
● Import of an Address Book
• The address book is imported after the existing address book in the host machine has been cleared.
• If an error occurs during import, the data is not returned to the state of data cleared before import.
• Addresses which exceed the number of addresses that can be registered are not imported.
• Group addresses which include addresses that were not imported are not registered.
• When entering the password for the address book from the Control Panel, if authentication is skipped, the address book is
excluded from the process.
● Import of an Address Book in an Old Format
It is possible to import an address book in an old format that was exported from a device not supporting DCM, but it is not possible
to export an address book in an old format.
There is no encryption password for an address book of an old format, but something needs to be entered, therefore a dummy
password (enter anything and the passwords will match) needs to be entered.
The specifications of import of an address book in an old format are as shown below.
• When an address book is imported, the consistency is checked while reading a record, not that the consistency of all records
is checked before import.
• If an accidental error (such as power discontinuity during import) occurs during import, the address book data which was
partially imported does not remain and returns to the state before import.
• Passwords such as the password for SMB are not recorded in an address book in an old format. Therefore these passwords
are not set in the address book to be imported.
• When an address book is imported, the data previously stored is not cleared but overwritten with the records stored in the
new address book. In other words, after the address book is overwritten with a new address book, some of the previously
stored records remain in some cases. All the registered call keys will be cleared.

• Even if other data (settings of menu, service mode, etc.) is specified as data to be imported, only the address book is imported.
• Addresses whose required field shown below is not filled in are skipped and the import process is executed. In that case,
the import process is continued without displaying an error message.
Type Required field
Group address Addresses included in the group
Fax Dial number
E-Mail E-mail address
File server (SMB) Host name (IP address) protocol
• When an address book is imported, if there is a field with an attribute that is not any of the foregoing required fields and
cannot be interpreted, import of only that attribute is skipped without abandoning the entire record. In that case, the import
process is continued without displaying an error message.
• If the number of characters exceeds the upper limit at import, the excess characters are truncated on the right.
Limitations
■ Job Control
Do not execute the following processes during import or export.
• Reception of a new job (Execution of calibration requested by the engine is allowed.)
• Firmware update (during which faxes cannot be received due to busy line.)
