B286/B289 6-100
SM
6.11.3 MCU, IPU
MCU (Main Control Unit)
This is the main control board of the machine. It does the following:
!
System
control
!
Base
engine
control
!
Scanner
control
!
Image
processing
The MCU also sends load signals and supplies power to:
!
Base engine (high voltage power pack, motors, sensors, solenoid, clutches, fusing unit,
RSS, etc.)
!
Scanner (sensors, motors, etc.)
The MCU contains two large blocks, connected by a UART: SCU and ECU.
!
SCU:
(System & Scanner Control Unit). Does overall system and scanner control.
