Abstract:
A belt drive system for multiple photoconductor drums, comprising:a series of photoconductor drums; a series of transfer rollers each adjacent to one of the photoconductor drums; a first roller disposed upstream from the first in the series of drums and a second roller disposed downstream from the last in the series of drums; an endless loop belt wrapping the first and second rollers, the belt having a generally horizontal upper run that carries media sheets and passes between and extends across the transfer rollers and the photoconductor drums, the upper run of belt simultaneously engaging each drum so that movement of the belt past the drums causes the drums to rotate as the belt carries media sheets past the rotating drums; grit particles randomly distributed along a portion of the belt that engages each drum such that the spacing between the grit particles is less than or equal to &frac13; mm.
