1.3 Power circuit

The power circuit generates 5V DC for the logic circuit, and 24V DC to energize the solenoids of the print head and two stepper motors.

1.4 Printer initialization

Printer initialization is accomplished in either of the two ways described below.

(1)initialization takes place automatically each time the primary AC power source is interrupted and reapplied (i.e., by turning the Power Switch off and on).

(2)Initialization may be initiated remotely by activating the INIT signal to the parallel
