(2) Feed paper from MPT
1. When the regist motor rotates (in clockwise direction) while the solenoid is
deactivated to the OFF state as shown in Fig. 2-3, the paper is transported
until the IN2 sensor is turned ON. (When the regist motor rotates in
clockwise direction, the MPT feed paper roller is activated)
2. Wh
en the paper turns ON the IN2 sensor, the specified amount of paper is
transported so that the paper is pressed against the regist roller U. (Thus,
paper skew is corrected)
3. Th
e regist motor rotates (in counter-clockwise direction) as shown in Fig.
2-4, the paper is transported by the regist roller U. (When the regist motor
rotates in counter-clockwise direction, the regist roller U is activated)

Transport belt
1. When the transport belt motor rotates in the arrow direction, the transport
belt is driven. The belt unit contains a single transport roller immediately
under the drums of each color in the manner that the transport belt is
pinched between them.
Whe
n the specified voltage is applied, the transport belt and the transport
roller send the paper from the transport belt to the fuser unit while
transferring the toner images on the drums of the respective colors.
