Additional logic uses the page and line sync from each print head to synchronize the accessing of the correct image raster from buffers at the output of the decompressor to the associated print head.

Abstract: By varying the spacing between a partially-reflective, partially-transmissive surface and a highly reflective surface positioned behind the partially-reflective, partially-transmissive surface, an interferometric modulator selectively creates constructive and/or destructive interference between light waves reflecting off the two surfaces. The spacing can be varied by applying a voltage to create electrostatic attraction between the two surfaces, which causes one or both surfaces to deform and move closer together. In the absence of such attraction, the surfaces are in a relaxed position, where they are farther apart from one another. A actuation voltage is needed to create sufficient electrostatic attraction to cause a surface to deform. The actuation voltage can be modified by implanting ions in a dielectric layer attached to one or both surfaces.
