KEY board:

This is the board on which each button switch and each LED on the control panel are mounted.

LDR board:

This is the board on which the laser diode and the ASIC are mounted. The laser is emitted based on the output image data signal from the ASIC on the LGC 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 ASIC on the LGC board.

LRL board:

This is the board to relay each signal transmitted between the LGC board and laser unit (LDR and SNS boards).

SFB board:

This is the board on which the circuit pattern is printed. It detects the position of the slide guide of the bypass unit.

ADU board:

This is the board to relay each signal between the ASIC on the LGC board and the electric parts (motor, sensor, clutch) in the ADU.

IH board:

This is the board to generate the electric power for driving the IH coil of the fuser unit from the AC electric power input via the switching power supply. And then it is provided.

SYS board:

This is the main board taking a leading part in all systems. It consists of the System-CPU, ASIC, memory (DIMM, SDRAM, Flash ROM, SRAM, NVRAM), RTC (Real Time Clock IC), etc. The System-CPU controls each ASIC to perform the control of the image processing, image memory (page memory, main memory, HDD), external interface (RS-232C, IEEE-1284, USB, PCI), NIC and FAX. Based on the input data from the control panel, the System-CPU communicates with the Scanner-CPU on the SLG board and Engine-CPU on the LGC board, and then issues an operation command to the scanner and printer engine section.

LGC board:

This is the board to mainly control the printing function (printer engine). It consists of the Engine- CPU, ASIC, memory (Flash ROM, SRAM, NVRAM), driver for motor drive, etc. The Engine-CPU controls each ASIC to drive I/O (for the electrical parts) of each section in the system. It leads to the operation of the laser unit, developer unit, drum, drawers, bypass unit, ADU, etc. Thus print- ing is performed.
