Figure 5.13 shows the paper feed mechanism for continuous forms. Continuous forms paper is loaded with its
sprocket holes fitted to the pins on the paper feed tractor belt and is fed by transmitting TR motor power to the
transmission mechanism to rotate the tractor belt. The paper fed by the front paper feed tractor is pulled by the
first and second rollers driven by the LF motor. Paper fed by the rear paper feed tractor is also fed in the same
way as with the front paper feed tractor and is pulled by the second and first rollers driven by the LF motor.
