• LDR board:
This is the board on which the laser diode and the ASIC are mounted. The laser is emitted based on
the image data signal output from the SoC on the MAIN board.
• SNS board:
This is the board on which the light sensor for detecting the radiating position of the laser is
mounted. It outputs the H-sync signal to the SoC on the MAIN board.
• PS-ACC:
This is the unit to generate each DC (high/low) voltage, which is used in the equipment, from the
external AC electric power input. This is then provided to each electric part.
• FUS board:
This is the board to provide AC electric power for driving the damp heater.
* Optional for NAD/MJD/CND model, standard for other models.
• CIS:
This is the unit witch performs optical-to-electrical conversion to convert the light reflected by the
original into the electrical signals. It consists of a light source (LEDs), optical system, CCD sensor,
etc.
• PFC board:
This is the board to control the optional Automatic Duplexing Unit (ADU) and optional Paper Feed
Pedestal (PFP).
• ADU board:
This is the board to control the optional Automatic Duplexing Unit (ADU). It detects paper feeding
with a sensor mounted on the ADU board.
