20130064589 | PIVOTING CLEANING BLADE TO MINIMIZE BLADE STRESS AND PHOTORECEPTOR TORQUE WITH INCREASING FRICTION COEFFICIENT - The cleaning blade is mounted to a holder that is pivoted. The pivot mechanism is designed such that the instantaneous center of rotation of the blade holder, in its operational position, is positioned above the plane of blade tip contact to the photoreceptor and upstream of the blade tip or below the plane of contact and downstream from the blade tip. These configurations result in a reduction of blade load as friction coefficient increases and a slower increase in photoreceptor torque when compared to conventional interference loaded blades. By a careful choice of the location of the center of rotation, the blade load can be maintained at a sufficiently high value for good cleaning over the expected range of friction coefficients. A four bar linkage provides a compact mechanism to pivot the blade holder and avoids potential problems of the mechanism interfering with the process and other components. | 03-14-2013 |
