.... d) Motor driver IC (IC401) Drives carriage motor and paper feed motor with steady currents generated according to the drive current signal data (serial data) it receives from the temperature sensors inside the print position sensor as a receive buffer, download buffer, print buffer,... feed count, and BJ cartridge mount/demount count. e) EEPROM (IC602) Controlled by the printer controller, the 16Mbit-DRAM is powered on the control board. Part 4: Technical Reference BJC-6000 A/D converter Detects the following analog signals: Internal temperature analog signal from the thermistor on ...
