An information processing apparatus includes an installation control unit configured to execute an installation of a program, validate predetermined information for the program and thereafter execute the program, and invalidate the predetermined information when the program is successfully executed, and a launching control unit configured to launch the program installed in the information processing apparatus when the information processing apparatus is started up, the launching control unit not launching the program, for which the predetermined information is validated.

An authentication operation of a communication device is facilitated without making an outer appearance of an image forming apparatus complicated. An image forming apparatus 1 includes an image reading portion 41 for reading an original image, an image forming portion 44 for forming the image on a recording material, communication devices 32 and 33 capable of communication with a storing device 52 for storing information through rear-range wireless communication, and a mounting portion 23 to which the communication devices are mounted, and the mounting portion is provided between the image reading portion and the image forming portion.

There is provided a motor driving system in which an encoder sensor is configured to move with a driven object with respect to an encoder scale and output an encoder signal. A controller is configured to control a motor based on the encoder signal, thereby controlling movement of the driven object. The controller estimates an obstructing area. In the obstructing area, the encoder sensor reads a part of the encoder scale where an obstacle is adhered. The controller calculates a control error of the motor in the obstructing area based on the encoder signal output after the encoder sensor passes through the obstructing area, and determines a compensation amount of a controlling input value input during a period while the encoder sensor passes through the obstructing area.

An information processing apparatus (20) includes: an operation/display portion (22); a reception processing portion (211) that receives a selection operation for selecting an objective related to setting a print job; and a display processing portion (214) that, when the reception processing portion (211) has received the selection operation, displays, among a plurality of setting items G22 to G29 related to the print job, a plurality of specific setting items G22 to G28 that have preliminarily been associated with the objective selected by the selection operation, in such a manner as to be distinguishable from the other setting item G29.

An image forming apparatus (1) includes a display (20), a detector (30), a determination section (101), a processing section (102), and an image forming section (140). The display (20) displays an image exhibiting a seating chart including a plurality of seat images. The detector (30) detects a first movement trace of a detection target on the display (20). The determination section (101) determines an order of the plurality of seat images based on the first movement trace. The processing section (102) processes an original document image to generate a plurality of output images respectively corresponding to the plurality of seat images. The image forming section (140) forms the plurality of output images on a plurality of sheets, respectively, in accordance with the order determined by the determination section (101). At least two output images of the plurality of output images are at least partially different from each other.

A print supply to connect to a printing device to provide a print material to the printing device that includes a machine and human readable print material gauge system, that includes an integrated circuit including a data interface to transfer print material level information describing a level of print material within the print supply and a display to represent the level of print material within the print supply.
