A sheet feeding apparatus includes a sheet conveying unit configured to convey a sheet along a conveyance path, a detecting unit configured to detect the sheet passing along the conveyance path, a control unit configured to determine an amount of delay of a sheet conveyed along the conveyance path based on the detection and determine information to be output based on the amount of the delay, and an output unit configured to output the information.

Even when descending of a sheet stacking unit is interrupted by an obstacle, sheet stacking operation is resumed in a range in which the sheet stacking unit is movable.

A user interface for a media processing apparatus is adapted to process image receiving media so as to determine a physical configuration of a media sheet. The user interface includes a screen, a controller adapted to receive image data specifying an image to be received on a sheet and to control the screen so as to display a preview showing the sheet with the image received thereon, an input section adapted to input preview editing commands, and an output section adapted to output set commands for the media processing apparatus. The controller is adapted to derive the set commands from the preview editing commands.

A sheet feeding apparatus includes a sheet conveying unit configured to convey a sheet along a conveyance path, a detecting unit configured to detect the sheet passing along the conveyance path, a control unit configured to determine an amount of delay of a sheet conveyed along the conveyance path based on the detection and determine information to be output based on the amount of the delay, and an output unit configured to output the information.

In a printing system, an attached-time remaining sheet amount at detecting attachment of a sheet feed tray to the printing system is detected. And current remaining sheet amount at end of image printing is detected. Then, it is determined whether the attached-time sheet remaining amount is greater than a first threshold value. In response to determination that an attached-time sheet remaining amount is greater than a threshold value and the current remaining sheet amount is less than or equal to the threshold value, a controller executes an alert process corresponding to controlling a display to display an alert. In response to determination that the attached-time sheet remaining amount and the current remaining sheet amount are equal to or less than the first threshold value, the controller inhibits executing the alert process.

A sheet feeding apparatus which is able to make it known that a first containing area for feeding cannot be replenished with sheets in a second containing area for replenishing. A sheet feeding cassette has the first containing area in which sheets to be fed are contained, the second containing area that is adjacent to the first containing area and in which sheets for replenishing are contained, and a sheet mover that transfers the sheets contained in the second containing area to the first containing area. A first detector detects whether or not the sheet mover is at a standby position. When the first detector detects that the sheet mover is not at the standby position, a warning is issued to prompt return of the sheet mover to the standby position.

An image forming apparatus includes a stacking portion including a lifting portion, a feeding member feeding a sheet stacked on the lifting portion to a conveyance passage, a position detector detecting movement of the sheet stacked on to a feedable position to the conveyance passage, a driver including a motor and performing the lifting operation of the lifting portion, a rotation detector detecting rotation of the motor, and a controller. The controller determines a factor that the position detector does not detect the movement of the sheet stacked on the lifting portion to the feedable position within a predetermined time based on a detection result of the rotation detector while controlling the driver to lift up the lifting portion.

Provided are an image forming apparatus and methods for controlling the apparatus, which includes a central processing unit (CPU) configured to set whether to operate an air blowing fan before a paper type detection sensor detects a type of sheet. In a case where a setting to blow the air is made by the CPU, the air blowing fan blows the air when a sheet feed unit feeds the sheet before the paper type detection sensor detects the type of the sheet. In a case where a setting not to blow the air is made by the CPU, the air blowing fan does not blow the air when the sheet feed unit feeds the sheet before the paper type detection sensor detects the sheet type.

A recording device includes an edge detection unit configured to detect an edge of a medium on a conveyance path, and a control unit configured to receive detection information from the edge detection unit, wherein the control unit acquires, based on the detection information from the edge detection unit, a direction of skewing of the medium and/or an amount of the skewing on the conveyance path and outputs skewing information including the direction of the skewing and the amount of the skewing.

A document reading apparatus includes a first discharge tray that assumes a closed state or an open state, by pivoting about a first pivotal shaft, a first transport route linearly extending from a document tray to the first discharge tray, a first reading device that reads an image of the document, a transport device that transports the document through the first transport route, and a controller that, when an instruction to read the document is inputted to an input device, restricts the transport device from transporting the document and the first reading device from reading the image, when the closed state or a full state of the first discharge tray is detected by a first detector, and allows the transport device to transport the document and the first reading device to read the image, when neither of the closed state and the full state is detected by the first detector.
