摘要： An image-forming apparatus includes a detachable consumable; a printer that prints an image using the consumable; and a controller that determines whether control information that is set for the consumable and that is for control of the printer exists. The controller extracts, when it is determined that the control information corresponding to the consumable does not exist, image information from an image of a predetermined test pattern printed by the printer, and acquires the control information generated based on the extracted image information.

摘要： An image reading apparatus according to an embodiment includes an image reading unit that generates reference data by reading a reference surface and generates image data by reading a sheet. A reference plate includes the reference surface for generating the reference data for shading correction of the image reading unit and a background surface for background of a sheet to be read to generate the image data. A control unit controls the positions of the image reading unit and the reference plate to be at a first position relative to each other when the reference data is to be generated and at a second position relative to each other when the image data is to be generated. The second position is different from the first position. A shading correction unit performs the shading correction in the image reading unit based on the generated reference data.

摘要： An object of the present invention is to detect the home position with a high accuracy without being affected by temperature. The present invention is an image reading apparatus having a reading portion, and the apparatus includes: an acquisition unit configured to acquire first data obtained by the reading portion reading a main scanning line in a state where a light source of the reading portion is turned on in a first light quantity, and second data obtained by the reading portion reading the main scanning line in a state where the light source of the reading portion is turned on in a second light quantity smaller than the first light quantity; a generation unit configured to generate difference data by subtracting the value of the second data from the value of the first data; and a determination unit configured to determine whether a mark arranged at a position corresponding to a home position of the reading portion has been detected on the main scanning line based on the difference data.

摘要： In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

摘要： A light source driving circuit that drives a light source includes a driving electric current generator that generates a driving electric current including a predetermined electric current, a first auxiliary current, and a second auxiliary current; and a controller that sets values of the first and second auxiliary currents by using first and second lighting pattern signals, wherein each of the first and second lighting pattern signals is for controlling supply of the predetermined electric current to the light source. After setting a first value of the first auxiliary current, a second value of the second auxiliary current is set by using the second lighting pattern signal that defines a time period for stopping supply of the predetermined electric current to be shorter than a time period for stopping the supply of the predetermined electric current that is defined by the first lighting pattern signal.
