摘要： A belt-conveyance control device includes a belt (30) that is supported by a drive roller (31) and a driven roller (32), a pulse motor (11) that drives the drive roller (31), and a first encoder (18) that is attached to the driven roller (32) to detect a displacement of the belt (30). The belt-conveyance control device controls a conveying speed of the belt (30). The belt-conveyance control device further includes a control unit that calculates a difference between the displacement detected by the first encoder (18) and a predetermined target value, calculates a pulse frequency of a driving pulse signal for driving the pulse motor (11) based on a feedback control based on the difference and a feed-forward control based on a reference driving pulse frequency, sets a control range of the feedback control to be equal to or smaller than a frequency of one rotation of the driven roller (32), and controls driving of the pulse motor (11) such that the belt (30) moves at a constant speed.

摘要： Systems and methods apply active feedback via a repetitive controller (522) to compensate for periodic disturbances applied by recording media to a movable image carrier having a controlled velocity. The compensation parameters of the repetitive controller (522), once the error signal of the feedback converges to zero, can be stored with one or more characteristics of the print job or the recording media used for the print job. When other print jobs are received having the same one or more characteristics, the stored, converged compensation parameters can be retrieved, reducing the time to convergence of the systems and methods.

摘要： In order for it to be possible to insert ribbons (1) of any desired length into a machine assembly (MA), for example transfer ribbons in an electrophotographic printing unit, the ribbon (1) is mounted on tubes (3) which are pushed into receptacles (6) which are arranged in the machine assembly (MA). Subsequently, sliding films are applied to the drive roll and/or deflection rolls (2, 8) which are arranged in the machine assembly, then the ribbon (1) is pushed with a gripper arrangement over the sliding films onto the drive roll and the deflection rolls (2, 8) until it has reached a setpoint position. Finally, the sliding films and the gripper arrangement are pulled from the machine assembly. The removal of the ribbon from the machine assembly takes place in the reverse sequence.

摘要： An image formation apparatus is provided that prevents a belt (18) from becoming displaced or detached from a belt unit (15). When a belt unit is detached from a main body casing, a tension roller (16) is fixed in an outwardly protruding position by a fixing member (551). Thereby, the conveyor belt (18) is stretched such that the conveyor belt is configured to be prevented from becoming displaced or detached. When the belt unit is mounted in the main body casing, fixation of the tension roller by the fixing member is released by a releasing protrusion (70) and a suitable operating tensile force is imparted to the conveyor belt by coiled springs (72) provided on the main body casing side.

摘要： A first stretch roller (21) stretches a secondary transfer belt at a position where a tip in a conveying direction of a recording medium (P) being conveying through a secondary transfer portion (T2) can reach thereto. The first stretch roller has a circumferential surface formed into a normal crown shape in which a straight area (21c) where a diameter of the first stretch roller is constant is provided at a center part in a direction of axis of rotation. A second stretch roller (22) has a circumferential surface formed into an inverse crown shape in which a straight area (22c) where a diameter of the second stretch roller is constant is provided at a center part in a direction of axis of rotation.
