Abstract: An image forming system includes a first image forming apparatus and a second image forming apparatus. The first image forming apparatus includes an image forming unit that at least forms an image of a first color. The second image forming apparatus includes an image forming unit that forms an image of a second color different from a color of an image formed by the image forming unit of the first image forming apparatus, and also includes an image forming unit that forms an image of the first color. The first image forming apparatus and the second image forming apparatus use the first color to form positional-adjustment images for adjusting image formation positions between the first image forming apparatus and the second image forming apparatus.

Abstract: An image forming apparatus as a first apparatus includes an image forming unit that forms an image onto a recording medium, a memory that stores first and second information, and a correcting unit that corrects an image formation position by the image forming unit in accordance with the first or second information. The first information is for correcting misregistration between a print position in the first apparatus and a print position in a second image forming apparatus as a second apparatus when an image is formed by the first apparatus and an image is subsequently formed by the second apparatus. The second information is for correcting misregistration between the print positions in the second and first apparatuses when an image is formed by the first apparatus, an image is subsequently formed by the second apparatus, and then an image is formed by the first apparatus.

Abstract: An image forming apparatus includes an image reading section that reads an image on paper to generate image data, and an image forming section that forms on paper an image based on image data. The image forming section forms on paper a dimension correction image including marks. The image forming section includes a computation unit that performs computation using dimension correction image data, obtained by reading the dimension correction image, to generate dimension correction data, and a memory that stores the dimension correction data. The image forming section corrects image data using the stored dimension correction data and forms an image based on the corrected image data. The computation unit has a first computation mode of generating first dimension correction data based on distances between the marks and a second computation mode of generating second dimension correction data based on distances between edges of paper and the marks.

Abstract: An image forming apparatus includes a document reading section and an image forming section. The document reading section reads a document image placed on a paper placement table and generates image data. The image forming section forms an image on a sheet of paper on the basis of the image data, and includes a memory that stores test data representing a test image, which is to be formed on a sheet of paper having a size larger than the size of the table, a correction-amount calculation unit that calculates correction amounts on the basis of image data representing the test image which is formed on the sheet of paper and which has been read by repeating an operation, and a correction-amount memory that stores the correction amounts. The image forming section forms, on a sheet of paper, an image corrected on the basis of the correction amounts.

Abstract: An information processing apparatus includes: a distance measurement sensor that outputs a voltage according to a distance to a measurement object; and a control unit that supplies power to the distance measurement sensor at preset intervals and stops the power supply after a preset first period has elapsed. When performing control to determine that the measurement object has approached the apparatus in a state where an output voltage from the distance measurement sensor is equal to or higher than a preset threshold value, the control unit supplies power again and stops the power supply after a preset second period has elapsed, and then performs control to determine that the output voltage from the distance measurement sensor is a falsely detected output voltage when the output voltage during the power supply is equal to or higher than a preset voltage.
