摘要： A medium feed apparatus includes a first sensor, a second sensor, a third sensor to detect rotation of the separation roller, and a processor. The processor controls a motor to put the separation roller on hold from when starting the feed of the medium to when the second sensor detects a front end of the medium and generate the drive force from when the second sensor detects the front end of the medium to when the first sensor detects a back end of the medium, and controls the motor to stop the feed roller while generating the drive force if the third sensor detects rotation of the separation roller in the opposite direction to the medium feed direction during feed of the medium.

摘要： A web-guiding system for guiding a web of media travelling from upstream to downstream along a transport path in an in-track direction, including a web-guiding structure and an air source. The web-guiding structure includes an exterior surface having a pattern of recesses formed into the exterior surface, wherein the web of media travels past the web-guiding structure with a first side of the web of media contacting at least some non-recessed portions of the exterior surface of the web-guiding structure. The air source provides an air flow between the first side of the web of media and the exterior surface of the web-guiding structure thereby providing a lifting force to lift portions of the web of media overlying the recesses away from the exterior surface of the web-guiding structure.

摘要： An image forming apparatus includes an image forming unit to form an image on a sheet, a conveyance roller, a motor, a gear train, a detection unit to detect motor driving current, a phase determination unit to determine a motor rotor rotation phase, and a control unit having first and second control modes. The control unit rotates the rotor to rotate the conveyance roller in a predetermined direction, and rotates the conveyance roller in a direction opposite to the predetermined direction. The control unit controls the driving current in the second control mode, and then switches, in response to a value corresponding to a rotor rotation speed having reached a target speed, from the second control mode to the first control mode to control the driving current. The target speed is a speed which corresponds to a speed when the conveyance roller conveys the sheet and is a constant value.

摘要： A method and device for feeding sheets one by one from a stack of sheets to a transportation device are described. The sheet-feeding device comprises a number of parallel, separately driven shafts which are equidistantly spaced from one another and are enclosed in a low-pressure chamber and carry a plurality of feeding wheels. A separating device is arranged above the low-pressure chamber. At least one relieving element is arranged in a vertically displaceable manner between a sheet-supporting position and a non sheet supporting position. Each relieving element is positioned before each wheel shaft and the movement thereof as well as the rotational movement of the wheels are controlled by the control unit depending on the position of the rear edge of the sheet relatively to the wheels.
