Abstract
An assembly for applying a tone to a document includes an elongated hollow casing, a rotatable print element mounted in the casing with a print applying surface extending outwardly from the casing, and a mechanism to supply the ink to the print element. The print element has tone applying projections, such as dots or lines, extending outwardly from it, and may comprise a roller rotatable about a fixed axis of rotation, a sphere, or an endless belt. Ink is applied to the print element with a piece of foam, or with a bundle of fibers. The foam is positively held in place in the casing with notches and ridges, and may have a wide variety of configurations, especially of the surface associated with the foam that engages the print element.
