    Abstract: An apparatus, method and printing machine that utilizes a ramped backer and/or a shock absorbing material in a cleaner subsystem to reduce or prevent photoreceptor motion quality disturbances. The shock absorbing material prevents an instantaneous high impact force between the spacer wheel and the photoreceptor backer bar that can cause photoreceptor motion quality disturbance. The ramped backer prevents the instantaneous deceleration of the spacer wheel with the backer that causes motion quality disturbance due to the shaking of the photoreceptor belt from the impact on contact. The combination of the shock absorbing material and the ramped backer create a preferred embodiment to prevent photoreceptor motion quality disturbance by the cleaner system.

    Abstract: In an electrostatographic copier wherein the fuser rolls are positioned closer than the dimensions of the copy sheet from the image transfer area, speed mismatch compensation between the fuser roll nip and the initial image support surface is provided by intentionally driving the fuser roll nip at a different pre-set velocity to form a buckle in the intermediate portion of the copy sheet controlled by selective cyclic reductions in the vacuum applied to a vacuum chamber sheet guide surface between the fuser nip and the initial image support surface, wherein the vacuum guide is in two areas, one of which is provided with a vacuum by the other, but is cyclically atmospherically vented.

    Abstract: PROBLEM TO BE SOLVED: To reduce or prevent a defect in the kinetic characteristic of a light receiving body caused by the impact between a cleaner spacer of the light receiving body and a backing member in a printer, etc. SOLUTION: The distance between a cleaner brush and the light receiving body (an image pickup surface, a belt, etc.), when the cleaner brush is moved in the direction of an arrow 105, is prescribed by a spacer wheel 100 and an inclined backing fixture 115. An impact absorbing material 180 prevents the instantaneous great impact force between the spacer wheel 100 and the inclined backing fixture 115, which may cause the defect in the kinetic characteristic of the light receiving body. The inclined backing fixture 115 gradually reduces the speed of the spacer wheel 100 by the inclination structure of the fixture 115. Therefore, the defect in the kinetic characteristic caused by the vibration of the light receiving body due to the impact when contact occurs is prevented. Thus, sudden speed reduction of the spacer wheel 100 with respect to the backing fixture 115 is prevented. Both of the impact absorbing material and the inclined backing fixture are used to provide a more suitable state.
