4. PRINTER ELECTRICAL SYSTEM

4.1 Overview of Printer Electrical System

The electrical system functions are handled by the logic section or power supply.
The logic section converts data from the interface into print signals or printer operation
signals, drives the BJ cartridge and motors, and monitors the sensor statuses.
The power supply unit converts the AC input power supply into DC driving power for
the logic board, motor, head and other parts.
When AC power is being supplied to the printer, all printer hardware components are
active except for the following: heater power supply VH and Vcc of the head; power
supply of photo interrupters (5) total; and head rank circuit.
