Abstract:
1. A printing apparatus, comprising: a scanning member positioned to read images on documents positioned thereover and forward image data for further processing; an image processor that receives the image data from said scanning member and processing it; at least one copy sheet feed tray adapted to feed copy sheets to receive images thereon from said image processor; and a finishing system adapted to receive the imaged copy sheets, said finishing system including a compiler system including a tray for receiving the copy sheets and compiling them into a stack, a stapler for stapling said copy sheets and a drive member for forwarding them as sets to an output tray, said compiler system including at least one paddle wheel having a hub with at least one paddle blade connected directly to said hub and extending orthogonally therefrom, and wherein said at least one paddle wheel includes a flexible shield connected directly to and extending orthogonally from said hub and positioned between said at least one paddle blade of said at least one paddle wheel and the top copy sheet of sheets stacked in said tray and configured to reduce drive force of said paddle blade against said stack in order to allow compiling of a greater range of stack heights with desired compiling behavior.
