Abstract: A media width detecting system is adapted to measure an absolute width of media without the need for human intervention or without the need for media to be referenced against a known location. The media width detecting system includes a measuring pattern that is provided across a media path for media. The measuring pattern can be in the form of, for example, a bar code pattern. The system further includes a reader that is provided relative to the measuring pattern so as to read the width of the measuring pattern. When media traverses the measuring pattern, a portion of the measuring pattern, for example, a subset of the bars of the bar code pattern, is covered by the media. The reader would then be adapted to determined a width of the measuring based on the covered portion of the media pattern in relation to the uncovered portion or uncovered bars.

Abstract: An imaging system comprising a source of light movable with respect to a writing element and projectable thereon to generate an image, a focusing system is provided for focusing a light source which generates a first beam of light of a wavelength selected to be actinic with respect to the writing element. At least a portion of the first beam of light is absorbed by the writing element. The system includes apparatus to automatically supply donor sheets and receiver sheets independently to a writing platen or drum, and to selectively load and unload the donor sheets from superposition with the receiver sheet without disturbing the registration of the receiver sheet.
