# Option Cassette Loading Mechanism

This mechanism is composed of the 2nd lift-up mechanism and 2nd ASF mechanism.

#2nd lift-up mechanism

This mechanism lifts the paper loaded on the 2nd Cassette Assy up to the paper pickup position.
The 2nd lift-up mechanism is driven by the drive force of the 2nd Lift-up Motor. The 2nd Lift-up Motor's drive force is transmitted via the 2nd Lift-up Gear Group to the 2nd Lift-up shaft and rotates the 2nd Lift-up shaft.

2nd Lift-up Motor's rotational direction and the operation of the 2nd lift-up mechanism

The 2nd Lift-up Motor drives the 2nd lift-up mechanism only. Therefore, the 2nd Liftup Motor never rotates counterclockwise.

#2nd ASF mechanism

This mechanism picks up paper on the 2nd Cassette Assy and feeds it up to the intermediate feeding mechanism on the printer. The retard separation method is used for paper separation; the same method as for the Cassette Assy.
The 2nd ASF mechanism is composed of the 2nd pick-up mechanism and 2nd intermediate feeding mechanism and driven by the drive force of the 2nd ASF Motor. The 2nd ASF Motor's drive force is transmitted via the 2nd ASF Compound Gear and to the 2nd Pick-up Gear Group and 2nd Intermediate Gear Group, and rotates the 2nd Pick-up Roller, 2nd Separation Roller, and 2nd Intermediate Roller.

2nd ASF Motor's rotational direction and the operation of the 2nd ASF mechanism

2nd pick-up mechanism

On the shafts of the Pick-up Roller and Separation Roller, the One Way Clutch is mounted. When the 2nd ASF Motor rotates counterclockwise, the drive force is cut off by the One Way Clutch, so neither the 2nd Pick-up Roller nor 2nd Separation Roller rotates.

2nd intermediate feeding mechanism

The Clutch Gear C, Clutch Gear D, 2nd ASF Spur Gear, and 2nd ASF Driven Shaft on the drive path between the 2nd ASF Motor and 2nd Intermediate Roller are the same configuration as of those in the one way drive mechanism*^1.Therefore, the 2nd Intermediate Roller rotates in the feeding direction only regardless of the rotational direction of the 2nd ASF Motor.
