2.1.2.2 C524 PSB/PSE/PSH Power Supply Circuit
This printer can be powered by one of the following three power supply boards: the
C524PSB (120 V) board, the C524PSE (230 V) board, or the C524PSH (Universal)
board. The function of the boards is the same, except for a difference in the primary
circuitry. The power supply outputs the DC current necessary to drive the printer
control circuit and drive the mechanism.
