2.11.4 BUS SWITCH BOARD (OPTIONAL)

From the copier
The printer controller is an option for this copier. The bus switch board interfaces
the copier with the controller.
The CIVIC interface between the controller unit and the bus switch board transfers
image data on an 8-bits/pixel basis for each color.
The FCI (Fine Character and Image) chip performs image smoothing and line
correction. When the user selects smoothing, the FCI converts the image data (8
bits) to 7 bits of image and 1 bit of pixel positioning data, which simulates 1200 dpi
resolution across the page.
