CHAPTER 5 PICK-UP/FEEDING SYSTEM
b. Decrease in the Stack
q When the stack decreases and, as a result, its top surface lowers a specific dis-
tance, the pick-up roller moves farther down during pick-up, causing the pick-up
roller shaft to push the lift-up releasing arm and the lift-up cam to be freed.
