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.

Image formation apparatus and storing medium

An image reading apparatus to read a sheet being conveyed includes a memory and a reading device to read one side of the sheet in units of a line area orthogonal to a conveyance direction of the sheet. A read image of a first region corresponding to a leading edge side of the sheet in the conveyance direction is stored into the memory. A read image of a second region subsequent to the first region is not stored. A read image of a third region subsequent to the second region and corresponding to a trailing edge side of the sheet in the conveyance direction is stored in the memory. Each read image is an image read by the reading device. Predetermined processing is performed based on the read image of the first region and the read image of the third region stored in the memory.

Image reading apparatus, control method thereof, and storage medium storing program

An image forming apparatus includes a storage unit that stores image data, an obtaining unit that obtains the stored image data, a printing unit that prints an image generated from the obtained image data on a sheet, a conveyance unit that conveys a sheet contained in a containing unit to the printing unit and conveys the sheet on which the image has been formed external to the image forming apparatus, and a detection unit that detects that the obtaining unit did not obtain the stored image data, where the conveyance unit stops conveyance of the sheet based on the detection by the detection unit during the conveyance of the sheet.

Image forming apparatus to obtain image data from storage

An image forming apparatus comprises a printer for forming an image on a sheet, an image scanner for reading a measurement image formed on a sheet, and a controller. The printer forms the measurement image at four corners of the sheet. The image scanner reads the sheet on which the measurement image is formed by dividing into two parts. The controller generates an entire read image of the sheet from the read image of the measurement image which is read by the image scanner by dividing into two parts. The controller generates an adjustment condition to adjust a position of an image formed by the printer based on the entire read image of the sheet. The controller causes the printer to form the image based on the adjustment condition.

Image forming apparatus and method for controlling image forming apparatus

An image processing apparatus includes first and second detecting units, a conveying unit, a reading unit, a setting unit, an executing unit, a storing unit, and a correcting unit. The first detecting unit detects a size of a set document. The conveying unit conveys the set document. The second detecting unit detects a size of the conveyed document. The reading unit reads an image of the conveyed document and generates image data. The setting unit sets a setting value based on the detected size before the document image is read. The executing unit executes image processing on the image data, based on the set setting value. The storing unit stores the image data. The correcting unit corrects, where the size detected by the second detecting does not match the size detected by the first detecting, the stored image data based on the size detected by the second detecting unit.

An information processing apparatus according to an aspect of the present invention includes an identifying unit configured to identify a printing capability of an apparatus that is a transmission destination of first image data, and a converting unit configured to convert the first image data, which has been instructed to be printed with a transparent recording material, into second image data that can be printed by the transmission destination apparatus, on the basis of the identification result of the identifying unit and information attached to the first image data.

Image processing system for producing copy protected images using transparent recording material

An image scanner using an area sensor having a tilt reads a plurality of low-resolution image data having phase shifts from each other, and the low-resolution image data are converted into those on an orthogonal coordinate system by affine transformation. The number of data to be used is decided based on one of these low-resolution image data. The low-resolution image data as many as the designated number of data are saved, and high-resolution image data is generated by executing super-resolution processing.
