Abstract
A belt drive operative to rotate one or more photoconductor drums while carrying media sheets past the rotating drum or drums. For single pass color printers in which the different color planes are developed using a series of photoconductor drums, a substantially flat movable belt is positioned adjacent to and extends across each of the drums. The belt simultaneously engages each drum so that movement of the belt past the drums causes the drums to rotate together as the belt carries media sheets past the rotating drums. In one preferred version of the invention, grit applied to the ends of the drum(s) and/or to the edge of the belt is used to transfer driving force from the belt to the drums.
