C. Non-Pick Up Operation (standby)
The machine operates as follows when the cassette is slid into or out of the machine.
1. Lifter Up/Pick-Up Roller Shaft Down (sliding in the cassette)
a. Pick-Up Roller Shaft Down
When the cassette is installed while the main power supply is ON, the following cause the pick-up roller
shaft to lower until it comes into contact with the surface of the copy paper:
•
The rear end of the cassette pushes in the lever 1 of the pick-up unit mechanically.
•
The main motor (M1) and the pick-up solenoid (SL2) turn ON in response to the activation of the cas-
sette size sensor, causing the pick-up lever to swing.
•
The pick-up roller shaft is subject to control by the lever 1 and the pick-up lever.

b. Lifter Up
When the main power is turned ON with the cassette inside the machine or the cassette is slid in dur-
ing standby, the pick-up roller shaft lowers to push down the lifter trigger lever.
When one end of the lifter trigger lever is pushed in by the pick-up roller shaft, the drive of the main
motor (M1) causes the lifter to rise.
When the pick-up roller shaft, which is in contact with the surface of copy paper, has moved up to a
specific height, the movement of the lever returns the pick-up roller shaft to uppermot position, ending the
lifter ascent operation.
