Abstract: An information processing apparatus includes a processor configured to: obtain electrical noise generated from a memory included in a target product; determine, for each of frequencies obtained by dividing a frequency spectrum of the electrical noise, whether the electrical noise falls within a predetermined range, which is determined in advance for the frequency; determine, if the electrical noise falls outside the predetermined range, whether the electrical noise falls within an enlarged range, which is obtained by enlarging the predetermined range; and determine that the target product is a genuine product if a sum of a number of frequencies at which the electrical noise falls within the corresponding predetermined ranges and a number of frequencies at which the electrical noise falls outside the corresponding predetermined ranges but falls within the corresponding enlarged ranges is larger than a number of frequencies at which the electrical noise falls outside the corresponding enlarged ranges.

Abstract: An image forming apparatus includes a reverse side print mechanism for printing on the reverse side of continuous paper, a surface print mechanism for printing on the surface of the continuous paper, and a width detecting mechanism for detecting a width of the continuous paper. The apparatus further includes a controller which, based on the detected paper width, determines a print start position on the reverse side of the continuous paper and controls the reverse side print mechanism to start printing from the determined print start position. Thus, even if the paper width is changed, the reverse side print start position can be set to a predetermined position.

Abstract: A printing apparatus for printing on double-sides of a recording medium has a first print control unit for controlling an one-line exposure for the right or reverse side by a horizontal synchronous signal, and a second print control unit for controlling the one-line exposure for the reverse or right side by using this horizontal synchronous signal. A print start timing for the right side can be synchronized with a timing for the reverse side, and is capable of preventing a deviation in print position between the right side and the reverse side of the recording medium even by providing the print control units for the right side and the reverse side, individually.

Abstract: A paper handling apparatus has a simplified structure and allows printed paper to be stacked efficiently. The paper handling apparatus receives printed paper which has undergone printing for each print job and handles the printed paper in an orderly manner. The paper handling apparatus has a stacking section in which printed paper is stacked sequentially for a plurality of jobs and an unloading mechanism for unloading stacked printed paper from the stacking section to the outside. The paper handling apparatus can be used with a printing apparatus which is connected to a large-scale information processing system or similar for printing a large volume of data.
