Overview

Together with the controller board, the FCU controls all the fax communications and fax features. The FCU also contains the ROM, SRAM and NCU circuits.

Fax Options

• Extra G3 Interface option
  This provides one more analog line interface. This allows full dual access. Two extra G3 interface options can be installed.
• Memory Expansion
  This expands the SAF memory and the page memory (used for image rotation); without this expansion, the page memory is not big enough for image rotation at 400 dpi, so transmission at 400 dpi is not possible.
