B. BASIC STRUCTURE 

1.

 

Power-Supply 

 

Primary - AC 50/60Hz 100V, 115 V, 220 V or 240 V   

 

 

Transformer for each AC voltage is selected at the  

 

factory. 

 

 

Note: There are four types of transformer. A  

 

 

 

selection of voltage is made at the  

 

 

 

factory-set in accordance with the customer's  

 

 

 

requirements. 

 

Secondary - DC 5 Volt for TTL Logics. 

 

 

 

  DC 19 Volt for Printer Mechanism. 

2.

 

CPU and Control Circuit Block 

 

 

Main Control Board with CPU, ATARI SIO Interface  

 

 

Board and Operation Key Board. 

3.

 

Printer Mechanism 

 

 

Printer Head, Head Carriage Mechanism, Paper Feed  

 

 

with Tractor Mechanism and Ribbon Driver Mechanism  

 

 

are in unit. 

 

 

The Printer head is replaceable but disassembling of  

 

 

the other parts of unit at the field is not  

 

 

recommended for repair. In case of the printer  

 

 

mechanism is defective, the whole printer mechanism  

 

 

unit should be replaced, and the defective one be  

 

 

sent back to the factory.
