OPERATING PRINCIPLES
2.2 POWER SUPPLY OPERATION
The printer can be powered by either of two power supply boards: the 120 V C204 PSB board or the 220/240 V C204 PSE board. The only difference in the operation of these two boards is in the primary circuitry. They supply power to the printer in the same way. The power supply board outputs the DC current required to drive the control circuits and printer drive mechanism. Table
