The ASF unit includes the hopper, change lever, LD roller shaft, and clutch mechanism. The change lever and the clutch mechanism play an important role in the paper loading operation as described below. 1. 2.

This causes the clutch to engage with the gear by being pulled by the extension spring.

The LD roller rotation causes the hopper release cam and the paper back lever cam to push down the hopper and the paper back lever respectively.
