Main Board Control
Main control is made of ASIC(CPU, Image processor, PC I/F part include, Scan interface part,
FAX Modem part and Printing process I/F part. CPU handles the BUS control, I/O interface, scan
interface, PC interface and other miscellaneous driver circuit.
1) Main Board
- Main Board has a function of sending Current Image Video Data to LSU of the machine,
controlling motor
Driving Circuit and monitoring Paper Exit Sensor, Cover Open switch, OPE Panel Inputs.
2) Main Controller
- CPU: Chorus2 is the main CPU and is made up on the 16/32bit RISC architecture using
ARM7TDMI core. Main CPU controls the whole system according to the program code which
stored in the Flash-ROM memory.
- Summary of the Key Function Block:
• 1.8V for internal Core, 3.3V for I/O Pad with 4KByte Cache.
• Image Processor included.
• On-Chip clock generator with PLL.
• Memory and External Bank Control.
• DMA Control (5-Channel)
• Interrupt Control.
• 2-port USB Host/1-port USB device (ver 1.1) interface control.
