Printer Functional Elements

(Figure 2–8 and Figure 2–9)

The printer is made up of the following functional elements:

•

Control Panel

•

Data Control Unit (DCU) PCBA

•

Mechanism Control Unit (MCU) PCBA

•

Mechanism Driver PCBA

•

Hammer Driver PCBA(s)

•

Hammer Bank and Shuttle Mechanics/Magnetic Pickup (MPU)

•

Power Supply PCBA(s)

•

Ribbon Deck

•

Paper Transport

•

Platen Open/Paper Out Switches

Figure 2–8 shows the basic interrelation of these elements and Figure 2–9 is

a simplified block diagram of the printer.
