When the power is turned ON, the off-set tray lowers to the lower limit
sensor (4) position. Then it elevates until the upper limit sensor (7)
turns ON, while counting the encoder pulses of the elevator motor (3).
The volume of paper loaded on the off-set tray is calculated (0 -
100%) by counting the number of pulses from the elevator encoder
(1).
The off-set tray is judged to be full when both the lower and upper
