18-3. Paper Level Detection
D 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 PC67/68 and a
pulse disk.
D The pulse disk is mounted on the shaft of the intermediary gear that transmits drive
from the Lift-Up Motor (M13/14). The speed of the pulse disk varies with different
paper levels and the number of pulses detected by the Lift-Up Motor Pulse Sensor
(PC67/68) is used to determine the paper level.
D Counting of the number of pulses is started when the Lift-Up Motor (M13/14) is en-
ergized and continues until the output from the Lift-Up Sensor (PC65/66) goes
LOW. 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.
D As the paper is consumed and the top level of the paper stack lowers, the Lift-Up
Motor is energized to raise the paper stack. During this time, the Lift-Up Motor Pulse
Sensor (PC67/68) 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.
