The controller employs GW (Grand Workware) architecture, which allows the board
to control all applications, including copier, printer, scanner, and fax applications.
To add the optional printer, scanner, or fax applications, ROM DIMMs must be
installed on the controller. The fax option requires the FCU and NCU installation.
The following systems and application software can be downloaded from the
controller's IC Card slot.
• Controller (System OS/Copier)
• Operation panel
• SBCU (engine control)
