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.
