Part 4: Technical Reference BJC-4400 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.
