This automatic overwriting of the document protection setting in the MFP Address Book can be disabled for all users in Service Program mode (SP5-401-103). The Document Administrator can also change the passwords for individual documents without having to clear a password-based authentication process. Page 33 of 86

Access Privileges and Operations for the Address Book

1-7-4 Document Server Documents (MFP models only)

The tables below show the various types of data stored inside Document Server management files, as

well as the various operations that can be performed on this data by general users, groups, owners,

and User Administrators. It is possible to assign general user access privileges to individual users as

well as to groups. Users who have not been assigned any access privileges are not able to view the

contents of these files.

There are four levels of access privileges: View, Edit, Edit/Delete and Full-Access. These settings can

be changed by Group and User Administrators, users with Full-Access privileges and the user who

registered the entry.

A password can be assigned to each document (4–8 numeric characters long), ensuring that the

document cannot be printed unless the correct password is entered first. In addition, if an incorrect

password is entered with the Document Lock feature enabled, the MFP will prohibit all further access

to the document in question. This setting can be enabled and disabled in System Settings by the

Document Administrator.

Every time a user logs in using Integration Server Authentication, the document protection setting in

that user’s Address Book stored in the MFP is automatically changed to “View (only)”. Therefore if the

user stores a file to the Document Server without changing the document protection setting for that

document, or stores the file from an application that does not allow the setting to be changed, the user

will not be able to edit or delete the document later. This automatic overwriting of the document

protection setting in the MFP Address Book can be disabled for all users in Service Program mode

(SP5-401-103).

The Document Administrator can also change the passwords for individual documents without having

to clear a password-based authentication process.
