A printing apparatus includes a feeding units, a detecting unit, a designating unit, and a control unit. The detecting unit detects a respective operation on each of the feeding units. The designating unit designates, in response to a user operation via a display, which of the feeding units is to be used for printing. The control unit executes, in response to a command to execute predetermined printing, a process based on a first feeding unit on which an operation has been last detected by the detecting unit and a second feeding unit designated by the designating unit. Based on that the first and second feeding units are different, the control unit displays, as the process, a predetermined screen on the display. Based on that the first and second feeding units are the same, the control unit executes, as the process, the predetermined printing on a second feeding unit fed sheet.

An image forming apparatus includes an image forming unit configured to form a predetermined pattern image on a sheet, a notifying unit configured to provide a notification of an orientation for placing the sheet on which the predetermined pattern image is formed by the image forming unit, on a placement portion, a reading unit configured to read the sheet on a line to line basis, to generate image data, and a detection unit configured to detect a streak-shaped image extending in a direction along a predetermined edge of the sheet, by analyzing the image data generated by reading the sheet by the reading unit, wherein the notifying unit provides a notification of a placement orientation for allowing the sheet, on which the predetermined pattern image is formed, to be read on a line to line basis, the line extending in a direction along the predetermined edge.

Provided is a printing apparatus including a cassette configured to be capable of managing a stored paper-sheet by using paper-sheet size information and paper-sheet attribute data, in which an adjustment value of a print position is registered to copied paper-sheet attribute data if an event in which the adjustment value is registered to paper-sheet attribute data in which the paper-sheet size information is not set occurs.

An image processing apparatus includes a document table, an image reading portion, a cover portion, a presser sheet, and a sheet winding portion. The presser sheet is provided on the cover portion, and contacts the document on the document table when the cover portion is positioned at the closing position. The sheet winding portion allows a first portion of the presser sheet to extend along the document table while holding a second portion of the presser sheet in a wound state. The sheet winding portion can feed the second portion when an external force is applied to the first portion. In the cover portion, a retreat space is formed so that the first portion of the presser sheet and a portion of the second portion fed from the sheet winding portion can retreat into the retreat space.

An edge detection apparatus for detecting an edge of a recording medium to be conveyed includes a light source, a plurality of photoelectric conversion element pixels, and a detection unit. The light source irradiates the recording medium with light. The plurality of photoelectric conversion element pixels are placed in a direction orthogonal to a conveyance direction of the recording medium and convert light reflected by the recording medium into an electrical signal. The detection unit detects the edge of the recording medium on the basis of a plurality of electrical signals that constitute an n-th (n≧1) electrical signal group obtained by dividing the plurality of electrical signals corresponding one-to-one to the plurality of photoelectric conversion element pixels, and a specified number of the electrical signals counted from a top of the plurality of electrical signals that constitute an n+1st electrical signal group.

A sheet feeder is provided. The sheet feeder includes a roller to feed a sheet, a motor to rotate the roller, and a motor controller to control rotation of the motor by a feedback control. The motor controller detects a condition of the sheet based on a value acquired in the feedback control at the time a load is applied from the sheet to the roller, while performing a stop control to stop the roller at a designated stop position. The stop control is performed after the motor is rotated in a direction opposite to a direction of feed of the sheet.

An image processing apparatus includes circuitry that estimates a first geometric transformation parameter for aligning first output image data with the original image data, the first output image data being acquired by reading a first output result, and a second geometric transformation parameter for aligning second output image data with the original image data, the second output image data being acquired by reading a second output result; associates, based on the first and the second geometric transformation parameters, combinations of color components of the first and the second output image data, corresponding to pixels of the original image data, to generate pixel value association data; determines, based on the pixel value association data, a mapping for estimating color drift between the first output image data and the second output image data from the original image data; and subjects the original image data to color conversion based on the mapping.

An image processing apparatus including a reader, a storage configured to store identification information, one or more setting operations, and one or more pieces of state information in association with each other, each setting operation being a previously-set operation of operations executable by the image processing apparatus, each piece of the state information indicating a predetermined apparatus state of apparatus states in which the image processing apparatus is allowed to be, and a controller configured to control the reader to read the identification information from a recording medium, acquire particular state information indicating a particular apparatus state of the image processing apparatus, and when determining that the acquired particular state information is coincident with a specific piece of the state information, perform a particular operation of the one or more setting operations that is stored in the storage in association with the specific piece of the state information.

A position detection device includes a background member, a reader, and processing circuitry. The background member has a higher absorption characteristic in an invisible wavelength region than in a visible wavelength region. The reader opposite the background member irradiates a recording medium having a mark and the background member with light of a visible wavelength to output a visible image or with light of an invisible wavelength to output an invisible image. The processing circuitry is configured to: detect an end position of the recording medium and a position of the mark on the recording medium from a read image output from the reader; and select the visible or invisible image as the read image used for position detection, according to an absorption characteristic of a color material forming the mark read by the reader and an absorption characteristic of the recording medium in the invisible wavelength region.
