15-10. 3rd Drawer Paper Level Detecting Mechanism
•
The amount of paper still available for use, or the paper level, of the Main
Tray is detected using 3rd Drawer Elevator Motor Pulse Sensor PC44 and
a pulse disk which detect the speed of 3rd Drawer Elevator Motor M27.
•
The pulse disk is mounted on the shaft of the intermediary gear that
transmits drive from M27. The speed of M27 is known by counting the
number of pulses using PC44.
When 3rd Drawer is Slid in
Counting of the number of pulses is started
when M27 is energized (to turn forward) and
continues until PC16 is blocked (
L
). The
total 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, M27 is energized (to
turn forward) to raise the paper stack. During
this time, PC44 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.
NOTE : If there is paper on the Shift Tray, the
copier detects that 500 sheets or
more of paper are left in the 3rd
Drawer as long as paper is left on the
Main Tray.
