Abstract:
A printing apparatus and method include a charging device positioned adjacent a photoreceptor that places a latent image charge on the photoreceptor. A donor device is adjacent the photoreceptor, and transfers marking material to regions of the photoreceptor that have received the latent image charge. In addition, a media path that is adjacent the photoreceptor causes at least one sheet of media to be placed on the photoreceptor and the marking material. A transfer assist blade that is also adjacent the photoreceptor, presses the sheet of media against the photoreceptor to cause the marking material to be transferred to the sheet of media. The apparatus also includes a controller that is operatively connected to the transfer assist blade. The controller causes the transfer assist blade to apply more pressure to leading and trailing portions of the sheet of media relative to the middle portion of the sheet of media.
