MECHANICAL OPERATION
4.1
BASIC OPERATION
The paper feed rollers [A], which are turned by the paper feed motor, feed paper
from the paper roll [B] through the cutter unit [C] to the paper leading edge
sensor [D] according to the signal from the copier. When the paper feed motor
starts, the copier CPU starts measuring the length of the paper. (The paper
length is measured by counting the number of steps as the paper feed motor
[stepper motor] turns.)
