4.PRINTER ELECTRICAL SYSTEM

4.1Overview of Printer Electrical System

The printer's electrical system can functionally be split into the logic (logic board and carriage board) and the power supply.

The logic converts the data received from the interface into print signals and printer command signals, and drives the BJ cartridge and motors while monitoring the various sensors.

The power supply distributes the DC input power from the AC adaptor into power supplies to drive the logic board, motors, and print heads, etc.

When the AC adaptor is connected to a power outlet and a DC supply is therefore input to the BJC-7100 printer (and the printer has not yet been turned on using the POWER button), all buttons except the POWER button are inactive, the photointerrupter sensors are inactive, and any signals input from the interface are ignored. In all other respects, the hardware is active.
