A roller unit for removing copy paper from an electrophotographic copying machine, the unit comprising a drive roller and an idler roller, each having a plurality of longitudinally extending portions where the diameter of every other portion is larger than its adjacent portions, the rollers being disposed adjacent one another so that the larger portions of the drive roller are adjacent the smaller portions of the idler roller, and a plurality of rings disposed about the rollers to establish a substantially uniform clearance not greater than 1.5 mm. therebetween so that if any of the copy paper is ignited within the copying machine, the fire will be extinguished because of the clearance between the rollers, the copy paper being delivered from the copying machine with a predetermined rigidity along its direction of movement because of the disposition of the rollers with respect to one another to thereby lessen the tendency for the copy paper to turn over as it is delivered from the copying machine.
