ABSTRACT:
A copier/printer that employs a plurality of roll media includes a paper path monitored by a plurality of dual use sensors. The first use of the sensors is to initialize the lead edge of each media roll and the second use of the sensors is as jam detectors. When media is coming from a position lower than other media rolls, each sensor along the paper path is used in a timing sequence to monitor the media lead edge and indicate a jam if the media does not reach particular sensors in accordance with the timing sequence.
