The paper fed from the fusing section passes through the paper exit roller and ejected to the top of the printer with its
printed side facing down. The transmit power for feeding paper is given by the transport motor (M2) and transmitted in the
order from 1 ~ B shown in the figure.s
The paper exit sensor (PC3) detects ejection of paper. This sensor uses a photointerrupter. During paper is passing
through the sensor, the sensor arm is pressed by the paper so that the end of the sensor arm engages with the photoint-
errupter. In this condition, the light emitted from the LED of the photointerrupter is blocked and does not reach the pho-
totransistor. Thus, the phototransistor turns OFF and the output of the photointerrupter is “H”. When paper has passed
the sensor, the sensor arm returns to the original position by spring force so that the end of the sensor arm comes off the
photointerrupter. Thus, the light emitted form the LED passes in the photointerrupter, the phototransistor turns ON, and
the output of the photointerrupter is “L”.
