2.1 Overview

This chapter describes the operating principle of the printer mechanism and electrical circuit.

2.2 Printer Mechanism Operating Principle

2.2.1 Printer Mechanism

The printer mechanism of this printer is composed of the printhead unit, paper feeding mechanism,

(

arriage) mechanism and the pump mechanism. The block chart for the printer mechanism is shown in

Figure 2-1. The printer mechanism has 3 motors:

motor, PF (Paper Feed) motor and pump motor.

Torque from the

motor moves the

in the column direction. PF motor sends torque to load, feed and

eject paper. The pump motor drives the pump mechanism. The release lever switches torque from the PF
motor side to the tractor side to feed continuous paper.
