15-6. 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
PC56/57 and a pulse disk.
•
The pulse disk is mounted on the shaft of the intermediary gear that
transmits drive from the Lift-Up Motor (M23/24). The speed of M23/24 is
known by counting the number of pulses using PC56/57.
When the Drawer is Slid in
Counting of the number of pulses is started
when M23/24 is energized (to turn forward)
and continues until PC56/57 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, M23/24 is energized
(to turn forward) to raise the paper stack.
During this time, PC56/57 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.
