4. PRINTER ELECTRICAL SYSTEM
4.1 Overview
The electrical system functions are handled by the logic section or power supply.
The logic section converts the data from the interface into print signals or printer
operation signals and drives the BJ cartridge and motors while monitoring the status of
the sensors.
The power supply unit consists of a built in AC adapter which provides DC output to
the logic board, motors, and head etc. When DC input power from the AC adapter is
being supplied, all of the hardware components are active.
