摘要： An image forming apparatus includes a paper feeding cassette, a first conveying unit, a lift mechanism, a motor, a second conveying unit, and a control unit. The controller drives the motor and, if a value indicating a movement amount of the tray moving from when the lift mechanism starts the lifting of the tray until when a position of the top part reaches a first position is a first value, matches a position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a second position and, if the value indicating the movement amount is a second value larger than the first value, matches the position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a third position lower than the second position.

摘要： A sheet feeding apparatus includes a sheet stacker, an air blower, a suction feeder, a lifting mechanism, an elevation detection sensor, an elevation detection sensor, a feed detection sensor, and processing circuitry. The air blower blows air to float an uppermost sheet of sheets stacked on the sheet stacker. The processing circuitry drives the lifting mechanism such that the sheet stacker is lifted by an elevation amount determined based on a sheet thickness of the sheets stacked on the sheet stacker, each time a sheet is detected when a number of sheets detected is smaller than a threshold number of sheets, and stops lifting of the sheet stacker until a sheet is not detected when the number of sheets reaches the threshold number of sheets, while repeatedly feeding the uppermost sheet and counting the number of sheets.

摘要： A sheet feeding cassette (21) includes a body part (31), a placement plate (33) disposed on a bottom plate (31a) of the body part (31), a shaft (61) extending along a width direction, a lift plate (35) configured to be turned around the shaft (61) to lift and lower a downstream end portion of the placement plate (33), and a pair of side cursors (37F, 37R). Both end portions of the shaft (61) are rotatably supported by the body part (41), outside in the width direction of the side cursors (37F, 37R) disposed at the most separate position. The side cursors (37F, 37R) each has an abutment wall (71F, 71R) abutting on a side surface of the sheet and a recess (79) externally fitted to the shaft (61) from above, and the recess (79) slides on the shaft (61) when the side cursors (37F, 37R) move in the width direction.

摘要： The present invention is directed to a paper feed system. The paper feed system includes: a paper feed apparatus configured to accommodate stacked paper and sense a paper shortage state and a paper replenishment completion state; a communication unit provided to be integrated with or correspond to the paper feed apparatus, and configured to transmit a paper replenishment request signal when the paper feed apparatus senses a paper shortage state and transmit a paper replenishment completion signal when the paper feed apparatus senses a paper replenishment completion state; and a first server configured to communicate with the communication unit. When a change in the weight of stacked paper is detected, a paper support plate is elevated by driving a motor. When a situation in which the paper support plate reaches a set remaining amount height, a paper shortage state signal is transmitted to feed paper.

摘要： Examples include: a leveling system for a top feeder of a printer, where the top feeder includes a media positioning arrangement. The leveling system has a detector for detecting reflected light and generating a three-dimensional image comprising media positioning regions corresponding to the media positioning arrangement on a top sheet of a media stack installed into the top feeder. Also, the leveling system has an actuator configured to adjust heights of different points of the bottom of the media stack. Further, it has a controller for selecting, based on the three-dimensional image, adjustments to the heights for improving leveling of at least one of the media positioning regions; and controlling the actuator to implement the adjustments.
