Canon Canon S600 Standard Color Printer for Personal Use DC motor driver IC504/505, Eeprom IC402

S600 Part 3: Technical Reference

d)DC motor driver (IC504/505)

The motor driver IC is for driving the DC motor (paper feed motor and carriage motor). This driver is a PWM (pulse-width modulation) IC that changes the current's pulse width to control the output. It thereby controls the motor. The pulse-width control is defined by the serial data (10 bit) from the printer controller.

e)EEPROM (IC402)

The 2 Kbit EEPROM controlled by the printer controller records the waste-ink absorption amount, page count, and BJ cartridge removal/installation count. The printer reads the EEPROM contents when AC power is supplied and records the data when the power is turned off.

f)Control ROM (IC102)

The 8-bit control ROM is written with a printer control program.

g)Stepping motor driver IC (IC503)

This is a driver IC for constant-current driving of the ASF motor. The driving method is 1-2-phase driving.
