Abstract
In an electrographic printing apparatus, a dielectric belt cleaning system includes counter-rotating pairs of adjoining cylinders mounted to a housing. A vacuum source forces the dielectric belt in free span against the surfaces of the cylinders which are covered by a directional raised nap. Residual toner on the belt is dislodged and drawn through a low pressure zone between each pair of cylinders leading to a filtered discharge outlet. The brushes are cleaned by their interengagement along adjacent cylinder surfaces where the cylinder brushes mesh and also between each cylinder brush and a rake therefor fixed to the housing.
