ABSTRACT:
Disclosed is a process which comprises providing an imaging apparatus equipped with a path for moving receiver sheets through the apparatus and having infrared sensors situated along said path, incorporating into the imaging apparatus a substantially transparent receiver sheet having coated on at least a portion thereof an infrared absorbing material contained in a polymeric binder, passing the substantially transparent receiver sheet along the path, wherein the infrared sensors detect the presence of the infrared absorbing material on the substantially transparent receiver sheet, and generating an image on the substantially transparent receiver sheet. This process enables the use of substantially transparent receiver sheets in imaging apparatuses employing optical sensors or detectors for locating and/or positioning receiver sheets in the apparatus without the need for opaque strips on the transparencies or separate opaque sheets attached to the transparencies.
