According to one embodiment, an image forming apparatus includes a conveying roller to convey sheets of different types along a conveyance path, a first sensor to detect a sheet being conveyed at a first position, a second sensor to detect the sheet being conveyed at a second position that is at a fixed distance downstream of the first position, a registration roller pair that is downstream of the second sensor, and a control unit. The control unit calculates a transit time for the sheet between the first position and the second position according detection results from the first and second sensors, and then sets a conveying distance for the sheet after the second position to be used for aligning the sheet against the registration roller pair based on the calculated transit time of the sheet.

A medium transportation device includes a supply roller configured to send a medium downstream, at least one stopper configured to be switched between a blocking state in which the at least one stopper blocks the transportation path and an open state in which the at least one stopper opens the transportation path, and a controller configured to perform skew correction control in which a leading edge of the medium is brought in contact with the at least one stopper in the blocking state to correct skew of the medium. The controller is configured to obtain information about a stiffness of the medium and, when a second medium having a lower stiffness than a first medium is transported, the controller switches the at least one stopper from the blocking state to the open state to end the skew correction control earlier than the skew correction control of the first medium.

A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

An image forming device includes: a print engine to form an image on a medium, a sensor to irradiate light onto the medium and to detect an amount of light transmitted through the medium, and a processor to control the print engine based on the detected transmitted light amount and temperature data.

A system for capturing images during production of printed material includes an optical device comprising a plurality of cameras arranged in an array with adjacent pairs of cameras having overlapping fields of view. An imaging controller device determines a layout of content on printed material, and determines, based on the layout, an optical system configuration profile. Determining the optical system configuration profile includes selecting one or more cameras for capturing images of regions of interest on the printed material and determining a trigger interval for triggering the selected one or more cameras. The imaging controller device triggers the selected cameras at times determined based on the trigger interval to capture images of the regions of interest on the printed material as the printed material moves in fields of view of the one or more cameras during production of the printed material.

An image formation apparatus includes: an image former that forms an image on a recording medium delivered along a predetermined delivery path; a first hardware processor that judges whether or not the recording medium is an envelope; a second hardware processor that acquires a basis weight of the envelope; a third hardware processor that determines, in case the first hardware processor judges that the recording medium is the envelope, control for forming an image on the envelope by the image former on the basis of the basis weight of the envelope acquired by the second hardware processor.

A predetermined image correction process is automatically performed on an image, and information for identifying that the predetermined image correction process has been performed is displayed in a state that an image having undergone the predetermined image correction process is being displayed.

An image forming apparatus includes: an image forming unit configured to form an image onto a sheet; a conveyance roller configured to convey the sheet through a conveyance path, the conveyance path including a curved path being bent; a sensor configured to read the image formed on the sheet conveyed through the conveyance path by the conveyance roller, the sensor being configured to read the image formed on the sheet when a part of the sheet is conveyed through the curved path; and a controller configured to obtain information related to a type of the sheet, and to control, based on the information, a conveying speed of the sheet conveyed by the conveyance roller when the sensor reads the image.

An information processing apparatus includes a processor configured to: obtain characteristic values including smoothness and basis weight of a recording medium; and identify the type of the recording medium on the basis of the smoothness and the basis weight.

An image reading apparatus executes a calibration processing of calibrating a reading unit when a medium detection sensor detects that a medium is present. The image reading apparatus executes the calibration processing each time a first time-period elapses in a state where the medium detection sensor detects that the medium is present after the calibration processing. When a start instruction of reading the medium is received, the image reading apparatus starts transport of the medium and causes the reading unit to read the medium on a basis of calibration information of a last calibration processing.
