12-5. Paper Level Detection
The amount of paper still available for use, or the paper level, of the 1st and 2nd
Drawer is detected by 1st/2nd Drawer Lift-Up Motor Pulse Sensor and a pulse disk.
The pulse disk is mounted on the shaft of the intermediary gear that transmits drive
from the Lift-Up Motor. The speed of the Lift-Up Motor is known by counting the
number of pulses.
When Drawer is Slid in
Counting of the number of pulses is started
when the Lift-Up Motor is energized (to turn
forward) and continues until Lift-Up Motor
Pulse Sensor is blocked (
number of pulses is translated into the
amount of paper which is shown on the
Touch Panel as a graphic marker in units of
50 sheets of paper.
During Copy Cycle
As the paper is consumed and the top level
of the paper stack lowers, the Lift-Up Motor
is energized (to turn forward) to raise the
paper stack. During this time, Lift-Up Motor
Pulse Sensor detects pulses and that pulse
count is accumulated. When the count
reaches 50 sheets of paper, one segment of
the paper level indicator on the Touch Panel
goes out.
