Lifter Control
■ Moving Up the Lifter
The lifter starts to move up when the compartment open/close switch (SW4) and the compartment open/close sensor (SR9)
detect that the compartment has been set in place.The lifter then stops when the paper level sensor (SR3) detects the top surface
of the stack of paper placed on the lifter.The deck lifter upper limit sensor 1/2 (SR4/5) is used to prevent damage otherwise caused
by the failure of the lifter to stop after the sensor lever blocks the paper level sensor (SR3).The machine is also equipped with a
protective mechanism by means of an obstacle sensor (SR8) used to prevent damage to the lifter cable and resin gears lest a
foreign object inside the compartment should hit the ceiling before the paper level sensor (SR3) detects the top surface of the
stack of paper.
■ Moving Down the Lifter
The lifter starts to move down when the compartment open switch is pushed until the lifter passes through the sensor lever of
the relay paper sensor (SR2). When paper is supplied in this condition, the lifter moves down to the position where the paper
passes through the sensor lever as the paper pushes the sensor lever. The lifter keeps moving down until the lifter passes through
the deck lifter lower position sensor (SR13) which detects maximum paper supply position each time when paper is supplied.

Remaining Paper Level Detection Control
The level of the paper remaining is detected by counting the pulses of the encoder for the lifter motor rotation sensor (SR14) that
represent the distance of movement of paper from the deck lifter lower position sensor (SR13) to the paper level sensor (SR3).The
encoder for the lifter motor rotation sensor (SR14) rotates in synchronization with the deck lifter motor (M3).When the relay paper
sensor (SR2) became OFF from ON during paper feed, the count value of the pulse is reset for the correction of the detection
error by the wire growth.The lifter position information is memorized in the EEPROM of the deck driver PCB. Therefore the lifter
position control is not performed after sleep again.The level of the paper remaining is indicated on the display on the host machine.
