●
When the Paper Descent Key is pressed or the drawer runs out of paper during a
copy cycle, the Lift-Up Motor is energized to turn backward to lower the Paper Lift-
ing Plate.

The Paper Lifting Plate is at its lower limit position when the segment gear mounted
on the same shaft as the Paper Lifting Arm blocks 1st/2nd Drawer Lower Position
Sensor ( ).

When the Paper Descent Key is pressed, Lift-Up Motor continues turning backward
even after the 1st/2nd Drawer Lower Position Sensor has been blocked and is
deenergized when the 1st/2nd Drawer Lower Position Sensor is unblocked ( ),
the blocking plate passing through the sensor. This unlocks the drawer and the
drawer is pushed approx. 70 mm out to the front by the spring placed in the rear of
the copier.

After the drawer has been unlocked, Lift-Up Motor starts turning forward and is
deenergized when the 1st/2nd Drawer Lower Position Sensor is blocked ( ).

The drawer is locked in position by the lock holder inside the copier when it is slid all
the way into the copier.
