Abstract: PROBLEM TO BE SOLVED: To provide a color printer which allows more accurate registration of images and excludes mutual influences between processing stations, and has a higher flexibility of productivity and device configuration. SOLUTION: A free sheet tandem color printing system comprises a plurality of print engines, having a predetermined paper path and a plurality of stations; transfix stations, each of which is included as one of the plurality of stations within each of the print engines; and registration systems which are provided above respective transfix stations and are configured, so as to position the leading edge of each sheet transported within the predetermined paper path so that it engages a nip at the transfix station at a precise time.

Abstract: PROBLEM TO BE SOLVED: To perform accurate positional control of a printer with respect to a paper without requiring an expensive encoder in an imaging system employing multiscan printing. SOLUTION: An imaging system 100 comprises a paper handling surface 110 having an uneven mark 250 intersecting the axis and moving a paper 120 in a direction substantially parallel with the axis, a carriage 130 mounted slidably on the paper handling surface 110 and adapted to contain a printer 140 sliding in a direction substantially orthogonal to the axis and parallel with the paper handling surface 110, and an optical sensor 200 arranged to be disposed in the axial direction during movement of the paper handling surface 110 and to detect movement of the paper handling surface 110 relative to the carriage 130 by monitoring the mark 250.

Abstract: PROBLEM TO BE SOLVED: To provide a mechanism for minimizing fluctuation in belt tension, in order to economically and effectively impart tension to a closed loop, such as a photosensitive body belt or an intermediate transfer belt or the parts of an endless belt in a copying device, and to provide an electrostatic copying device equipped with the mechanism. SOLUTION: The tension-imparting mechanism (8) includes a 1st assembly (210), including a movable member (202) attached in a crossing direction with the acting direction of the movable endless belt (10) and coming into contact with the belt and a 1st rotatable arm (212) which has a 1st end connected to the movable member and a 2nd end coupled with a 1st pivot (218), and a 2nd assembly (220) which includes a tension imparting means (221) and a 2nd rotatable arm (222) having a 1st end connected to the movable member and a 2nd end coupled with a 2nd pivot (228).
