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.
ECU:
(Engine Control Unit). Does print engine and image processing control.
The MCU DIP switches must always be OFF (default) and they must not be changed in
the field.
SIPU (Image Processing Unit)
The SIPU (Scanned Image Processing Unit) processes image data from the CIS (Contact
Image Sensors), sends the data to the VDB (Video Drive Board). The VDB sends the data the
LPH (LED Print Heads) which writes the image on the surface of the durm. The SIPU also
controls the HDD and the printer/scanner interface.
The SIPU DIP switches must always be OFF (default) and they must not be changed in
the field.
