Fiber optic bundle and method of manufacture

A bundle of optical fibers having a linear first face and an area second face includes a frame for constraining the linear face to a geometry which compensates for any potential misalignment of pixels due to the movement of an electrostatic drum juxtaposed with the linear end. The fiber optic bundle is made of ribbons of optical fibers. The frame includes an elongated opening of a shallow sawtooth geometry where each "tooth" has a width to accept a ribbon and an offset at one end to raise the respective edge of the ribbon in a direction opposite to that in which the drum is moving.
