Abstract
Transfer deletions are reduced in a xerographic copy machine by imparting a curvilinear shape to the copy paper as it passes through at least a portion of a transfer zone. In a first embodiment, a fixed shoe constrains movement of a photoreceptor belt thereover, while a second preferred arrangement uses a roller to impart the curvilinear shape to the paper. In still another arrangement, a baffle that feeds the copy paper to the transfer zone is oriented with an existing roller structure to shape the paper as desired, and the baffle may be movable to vary the shape as the paper moves into the transfer zone.
