Printing & Imaging
Of course today many printing units take the form of xerography type units or “imaging” which encompasses feeding, printing and copying. Imaging can use large film belts as well as smaller unsupported stretch/elastic belts operating in sets on common shafts to move letter and legal sized paper through the machine. These often work in conjunction with rollers. Timing belts are used at the ends of shafts to drive and synchronize functions in the machine.
