The main PCB (MPCB) consists of the main CPU and operation unit CPU. The main CPU U8 communicates with other
PCBs, the image processing system and the engine drive system. The operation unit CPU U26 controls the LCD display
and the entire operation section.
The main CPU U8 operates on an 8-bit bus. It uses the SRAM U11 and U56 for work memory and FLASH U9 for backup
memory. In accordance with the control program in the main CPU FLASH U7, the main CPU U8 communicates with the
operation unit CPU and optional devices via the serial communication function in the CPU and XIO U14 and U15. The main
CPU U8 controls the CCD PCB (CCDPCB), which is for image input control, and the LSU, which is for image output control
via the image processing ASIC MIP U21, and drives the machine, conveys paper and detects abnormalities via XIO U14,
U15 and U22.
The operation unit CPU U26 operates on an 32-bit bus. It uses the SRAM U25 for work memory. In accordance with the
control program in the main CPU FLASH U29, which also contains LCD display fonts, the operation unit CPU U26 controls
key switches and LEDs on the operation unit PCB (OPCB) and controls the LCD display via the LCD controller U24.
