Abstract: An image reading device includes a white reference member, reading device, and processor. The reading device includes lenses and light-receiving elements. The light-receiving elements output a plurality of pixel values based on a light reflected from the white reference member. Each lens corresponds to at least two light-receiving elements. Each light-receiving element is configured to receive a light reflected from the white reference member and passing through the corresponding lens and to output one pixel value. The processor acquires the pixel values by using the reading device, sets a target pixel, and determines that the target pixel is an abnormal pixel when an absolute value of difference between a pixel value of the target pixel and a pixel value of a first pixel is greater than a prescribed threshold. The first pixel is separated from the target pixel by an integer multiple of the predetermined lens-to-lens distance.

Abstract: Local operation of an image forming apparatus is permitted from a tablet terminal only in a case where the tablet terminal is in the vicinity of the image forming apparatus. To achieve this, the position of the tablet terminal is determined by GPS. Alternatively, the position of a user holding a tablet terminal is determined using a local authentication unit of the image forming apparatus. Local operation is permitted if the user of the tablet terminal is within a predetermined range with respect to the image forming apparatus.

Abstract: A startup operation control apparatus includes a main-power-source operation unit, a determining unit, a memory, and a controller. The main-power-source operation unit is operated to supply and shut off power from a power source. The determining unit determines whether or not the main-power-source operation unit has been operated. The memory stores, every time an operation mode of a processing device that operates by receiving power supply from the power source changes, information representing the changed operation mode in an updating manner. If the determining unit determines, upon a shift from a power shutoff state to a power supply state, that the main-power-source operation unit has not been operated, the controller performs control so that the processing device operates in the operation mode represented by the information stored in the memory.

Abstract: Disclosed is a processor-implemented method for limiting ink output of marked image data using a target printer. A processor determines a constrained output (CMYK) LUT node data set for outputting the image data using the target printer to thereby mark the image data using a limited amount of ink. The constrained set is determined by re-encoding an encoded emulation output data, i.e., constraining an initial LUT node data set for the target printer based on a second. ICC profile with a smaller gamut. This allows the printer to inherit the smaller gamut. By constraining the initial LUT as disclosed herein, the final, constrained set emulates the smaller gamut in the target printer without suffering from pathological outcomes. The method enables the printer to inherit a natural ink limit methodology for the output colors that is more relatively proportional, and in a single destination profile.
