Abstract: An information processing device includes a retaining unit and an image display. The retaining unit retains image-formation-related information of an image forming apparatus that forms an image. The image display causes a display section of a portable terminal having the display section and an image capturing section to display an image for assisting with an operation of the image forming apparatus based on a captured image result of the image capturing section and the image-formation-related information retained in the retaining unit.

Abstract: An image forming device includes a receiver, a generator, and a controller. The receiver receives, from an external device, print instruction information including print data described in a page description language and a first image generated from the print data by the external device. The generator generates a second image from the print data included in the print instruction information. The controller compares the first image and the second image with each other and causes a display to display misregistration of the first image and the second image as a comparison result.

Abstract: An image forming apparatus includes an input unit that inputs an image forming job, a raster image generating unit, a transport path, a plurality of image forming engines, a calculating unit that calculates the displacement amount between the formation position of the pattern formed by each image forming engine and an ideal formation position thereof, and a controller that supplies each of the plurality of image forming engines with a driving signal instructing formation of a blank image during the time period when the calculated displacement amount is larger than a second threshold value, supplies each of the plurality of image forming engines with a driving signal instructing formation of the image corresponding to each raster image generated by the raster image generating unit and a preset mark when the displacement amount is smaller than the second threshold value.
