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 interface connector. This line should be driven by a TTL driver or its equivalent.
