    6.16  COPY DATA SECURITY UNIT 
    6.16.1 GENERAL FUNCTION 
    This function can prevent unauthorized copying by making a special masking pattern with 
    an embedded message when an original is printed. This enables the machine to make 
    grayed-out output when it is copied. 
    Confidential documents can never be duplicated on a machine that has the optional Copy 
    Data Security Unit. 
    The embedded messages appear when a confidential document is copied on a machine 
    without an optional Copy Data Security Unit. 
    However, some MFP functions are disabled if this function is enabled. 
    ƒ  Reduction less than 50% is disabled. 
    ƒ Scanner/Fax application is disabled.

    6.17  FILE FORMAT CONVERTER (MLB) 
    In this machine, this conversion is hardware-based, using the optional File Format 
    Converter. Without the File Format Converter, copy and print jobs cannot be downloaded to 
    a PC (or e-Cabinet) from the document server. 
    Two common target formats are provided for conversion to files that can be selected by the 
    SP modes: These are JPEG and TIFF. 
    In scanner mode, users can select file format from TIFF, JPEG, or PDF. The time to create 
    TIFF and JPEG files is shortened with the File Format Converter, especially for high 
    scanning resolution and large image size. When the customer selects PDF, the machine 
    creates a TIFF or JPEG file from the scanned image first. Then it converts it to PDF. 
    Therefore, the total time to create a PDF is also shortened with the File Format Converter.

    6.18  DATA OVERWRITE SECURITY UNIT (B735) 
    6.18.1  AUTO ERASE MEMORY 
    A document scanned in the copier or scanner mode, or data sent from a printer driver for 
    printing, is stored temporarily on the hard disk of the machine. The document stays in the 
    hard disk as temporary data even after the copy or print job is completed. Auto Erase 
    Memory erases the temporary data on the hard disk by writing over it. 
    Types of Data Overwritten and Not Overwritten 
    The following table shows the types of data that can or cannot be overwritten by Auto 
    Erase Memory. 
     
    Copier Copy jobs 
    Printer 1) Print jobs 
    2) Sample Print/Locked Print jobs(*1) 
    3) Spool Printing jobs 
    Scanner(*2) 1) Scanned files sent by e-mail 
    2) Files sent by Scan to Folder 
    3) Documents sent or retrieved by using Web 
    Image Monitor, Desk Top Binder, or Scan 
    Router

    Auto Erase Memory 
    Document 
    Server Temporary data that still remains in the 
    Document Server even after user erases the 
    data in the Document Server. 
    Data not overwritten 
    by Auto  Erase 
    Memory 1) Documents stored by the user in the Document Server using 
    the Copier, Printer or Scanner functions

    executed.  
    						
    							 
    B230/B237 6-98  SM 
    ƒ  *2: Temporary data via TWAIN scanner function are not originally stored in HDD. 
    You can use TWAIN scanner functions together with the DOS unit. 
    ƒ  *3: Data stored in the Address Book can be encrypted for security. 
    Overwrite timing 
    Overwriting starts automatically once a copy, print or scanner job is completed. 
    Copier, printer and scanner functions take priority over the Data Overwrite function. If a 
    copier, printer or scanner job comes while a previous job is being overwritten, the overwrite 
    process is automatically interrupted until the next job is completed.
