For Feeding Sheet From Stack Or Pack Holder Patents (Class 400/624)
  • Patent number: 10723154
    Abstract: An image forming system has a transmission assembly, standard and auxiliary sheet feeders, standard and auxiliary trays, an image forming device and a controller. The transmission assembly is for switching transmission of a drive force of a motor selectively to the one of the standard and auxiliary sheet feeders. The controller determines whether sheet is absent in the standard tray. The controller, based on determining the sheet is absent in the standard tray and receipt of preceding data, control the transmission assembly to initiate to switch the transmission of the drive force to the auxiliary sheet feeder. Also the controller, based on receipt of control data received after preceding data, control the image forming device to form an image based on the control data.

  • Patent number: 8297862
    Abstract: An image forming apparatus and a method to control the same. The image forming apparatus variably outputs the PWM signal until the printing medium reaches the target position, accelerates the printing medium-feeding motor, and decelerates the printing medium-feeding motor in multi-stages. If the printing medium reaches the target position, the image forming apparatus decreases the PWM signal value to a predetermined value, maintains a current level, and stops the printing medium-feeding motor without rotating the printing medium-feeding motor in the reverse direction, such that the printing medium-feeding motor may instantaneously rotate in a reverse direction. As a result, the image forming apparatus can prevent the printing medium from stopping the feeding operation without reaching the printing medium to the target position due to the instantaneous reverse rotation of the printing medium-feeding motor, such that the printing medium can be maximally/correctly transferred to the target position.

  • Patent number: 7946776
    Abstract: A sheet feeding procedure supplies recording media from a medium enclosing portion to a medium conveying path. An overlap-feed detecting procedure monitors a thickness of recording media supplied to the medium conveying path, thereby detecting the overlap-feed media. Sheet returning procedures (A) and (B) return the overlap-feed media into the medium enclosing portion when the overlap-feed media are detected. A looseness forming procedure applies rotational forces of different rotation speeds to upper and lower surfaces of the overlap-feed media during the medium returning procedure, thereby forming a looseness in the overlap-feed media. A medium re-feeding procedure supplies again the returned recording media to the medium conveying path from the medium enclosing portion. In the medium feed control, the overlap-feed can be further certainly recovered.

  • Patent number: 7934882
    Abstract: A printer is equipped with a supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette; a pair of feed-in rollers for sending the piece of sheet supplied from the supply roller toward a printing region; and a sheet sensor provided between the supply roller and the pair of feed-in roller. The printer rotates the pair of feed-in rollers in a forward direction in a case that the sheet sensor detects presence of the sheet at a timing when it is found that printing data for a subsequent sheet is not stored within the printer. On the other hand, the printer rotates the supply roller in a reward direction when the sheet sensor detects non-presence of the sheet at the timing when it is found that the printing data for the subsequent sheet is not stored within the printer.
