Abstract
In an imaging apparatus utilizing a carriage member arranged to carry a writing element, the carriage member and the writing element each have at least one surface with at least one of the surfaces having a discontinuity therein. A light beam is movable with respect to the writing element and is projectable thereon to generate an image. A light beam focusing system is provided for focusing the light beam with respect to the writing element and includes an element for sensing at least one of the surfaces of the writing member and the carriage member to control the focusing means. A discontinuity indicator is provided to indicate when the discontinuity in the surface is proximate the surface sensor, and an inhibitor is responsive to the indicating means to inhibit the output of the surface sensor when the discontinuity is within its range to prevent the focusing system from focusing on the discontinuity.
