This machine uses the GW (Ground Work) architecture, which allows the copier to
be expanded as an MFP by installing simple modular components (ROM DIMMs)
on the controller board.
1.
Controller (Main Board)
Controls the memory and all peripheral devices.
2.
SBCU (Scanner & Base Engine Control Unit)
This is the scanner and engine control board. It controls the following functions:
•
Engine sequence
•
Timing control for peripherals
•
Operation control
•
Drive control for the sensors, motors, and solenoids of the printer and
scanner
•
High voltage supply board control
•
Serial interfaces with peripherals
•
Fusing control
3.
IPU (Image Processing Board)
This is the scanned image processing board. It controls the following functions.
•
Image processing control
•
Video control
4.
SBU (Sensor Board Unit)
The SBU deals with the analog signals from the CCD and converts them into
digital signals.
