The controller employs GW (Ground Work) 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, however, requires FCU and NCU
installation also.
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)
• Printer
• Scanner
For details about how to download software from an IC card, see "Software
