Abstract

An electrophotographic printing machine records an electrostatic latent image on a photoconductive member which is developed with developer material by a development system. In the development system, the spacing between the developer roll and the trim bar is critical to copy quality. Usually the trim bar gap is set during manufacturing assembly. Often special equipment is used. The trim bar is positioned and then locked in place with mounting screws. If the trim bar needs to be removed to service the development system, this setting is lost. In the field, service representatives will often attempt to reset the trim bar gap. However, they cannot duplicate this setting as they lack the precise equipment used during manufacturing assembly. 'To solve this problem, the trim bar is mounted on a mounting block. The mounting blocks are adjusted to position the trim bar to the desired gap and secured in place. The edge of the trim bar trim bar is located by a notch in the mounting block. In the event the trim has to be removed from the mounting block, it may be reinstalled without any requirement to readjust the gap.
