摘要： The present application is directed to sensors and methods of use to determine a width of a media sheet moving along a media path. In one embodiment, the sensor includes a shaft that extends at least partially across the media path. First and second paddles may extend outward from the shaft and into the media path. The paddles may be axially spaced apart along a length of the shaft, and the first paddle may be positioned upstream along the media path from the second paddle. A flag may extend outward from the shaft. A detector may be positioned in proximity to the shaft. In use, the shaft may rotate during contact between the media sheets and the paddles to move the flag. The detector may be able to differentiate between a first amount of rotation due to contact with a wide media sheet and a second amount of rotation with a narrow media sheet to determine a width of the media sheets.

摘要： The present application is directed to methods of determining a width of a media sheet moving along a media path of an image forming apparatus. The methods may include moving the media sheet along the media path and past a media width sensor that includes a shaft with a first upstream paddle positioned away from a reference location of the media path and a second downstream paddle positioned in closer proximity to the reference location. The first paddle is positioned a first distance from the first sensor, and the second paddle is positioned a second distance from the first sensor. As the media sheet moves along the media path, a first signal may be received when the media sheet contacts the first sensor, and a second signal when the media sheet is at the media width sensor. The distance the media sheet travels between contacting the first sensor and being at the second sensor may be determined. The method may also determine whether the media sheet contacted the first or second paddle based on the media sheet travel distance. Based on which paddle was contacted, it may then be determined whether the media sheet is wide or intermediate. The method may also include determining the media sheet is narrow if there is no receipt of two signals.

摘要： A system, method and article for adjusting the time interval between feeding of successive sheets of media in a printer or copier. The method comprises initiating a first pick signal for a sheet of the media and identifying a feed time for the sheet of media, and identifying an expected feed time for said media. The system compares feed times to an expected feed time and adjusts according to such comparison to substantially correct for slippage or other problems feeding diverse media.

摘要： A system and drive arrangement for using fuser temperature cycling to change rotational position of a fuser roller wiper includes a frame, a hot roll, a fuser roller, and a drive arrangement. The frame of the fuser unit has side panels spaced apart from one another and positioned alongside a media path through the fuser unit. The hot roll on the fuser unit is rotatably mounted to the side panels of the frame and extends between the side panels across the media path. The fuser roller wiper is rotatably mounted between the side panels of the frame and performs a wiping action on the hot roll to remove foreign matter therefrom and supply of lubricant thereto. The drive arrangement is coupled to the fuser roller wiper and is operable in response to decrease in temperature of the fuser unit to rotate the fuser roller wiper.
