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.
