ABSTRACT:
Apparatus and process for producing multi-sheet, collated copy sets of a multi-original document with apparatus for monitoring the copy sets for confirming that each copy set contains all of the sheets, and has no grossly skewed, or unwanted duplicate or blank sheets. First electrical information signals characteristic of the images on the originals and second electrical information signals characteristic of the images on the copy set sheets are compared to produce an error signal representative of differences therebetween. A malfunction of the copier/printer is indicated in response to error signals of at least a predetermined magnitude.
