ABSTRACT:
In the present invention, a drive means for use in a printer or copier is described which will transport a recording medium, such as paper, having liquid images on one surface thereof without inadvertently causing the recording liquid to be pushed from the still wet image areas into non-image areas, thereby reducing print quality. This transportation of a recording medium with wet images without degradation of print quality is accomplished by a drive means comprising a drive roller having a high friction surface which is rotatably mounted beneath and tangent to a planar path of movement for the recording medium and a toothed idler roller having spaced teeth with rounded distal ends which extend from a hub to form a nip with the drive roller through which the recording medium is transported. The teeth have a predetermined height from the hub and a predetermined spacing between teeth. The distal ends of the teeth have a surface which is of a material that is not wetted by a recording liquid.
