PCB ORGANIZATION
GW controller architecture allows a basic 600-dpi copier to be upgraded to a full
multifunctional product, including printing, Internet, scanning, scan-to-email, and
scan-to-folder with Scan Router.
Boards
The BCU controls the machine.
The IPU controls the image processing.
The IOB controls the mechanical components. It also performs process control,
transfers serial data between the machine and peripherals, and controls the
fusing unit.
The PSU (Power Supply Unit) supplies direct current for every electrical
component in the machine, and controls alternating current input to the fusing
lamps and anti-condensation heaters.
File Format Converter (MLB): The file format converter (also called the "Media
Link Board" or "MLB") allows you to download copy and print data through via
network with Desk Top Binder.
CIS: A contact image sensor is used instead of a CCD. The main scan width is
A0. The resolution is 600 dpi.
LPH: This is the LED print head. It consists of three A3-width LED heads, to
write a main scan width of A0. The resolution is 600 dpi.
VDB: This drives the LED print head.
RFDB: These control the roll tray units, one for each tray (upper/lower).
FPDB: These control the fusing pressure motors. As stated earlier, the fusing
unit adjusts fusing pressure automatically. It uses two motors, which are each
controlled by one of these boards.
