(1) Paper Feeding from the 1st Tray
1. As shown in Figure 2-1, while the solenoid is on and the resist motor turns
counterclockwise, a sheet of paper is transported until the IN1 sensor is on. (When the
solenoid is on, the paper feeding roller operates.)
2. When the paper turns the IN1 sensor on, a certain more sheets of paper are
transported and thrusted against the resist roller. (This process corrects the paper
skew.)
3. As shown in Figure 2-2, turn the solenoid off and transport the paper by the resist roller L.
(When the solenoid is off, the resist roller operates.)

(2) Paper Feeding from Manual Feeder
1. Thrust the paper against the resist roller U. (This process corrects the paper skew.)
2. As shown in Figure 2-3, the resist motor turns counterclockwise and the paper is

resist roller U drives.)
