Abstract: Cleaning systems for an electrostatic imaging member and printers having cleaning systems are provided. In one aspect, a cleaning system has a wiper, a mounting holding the wiper so that an extension length of the wiper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the wiper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the extension length with the wiper resiliently bending to fit within the extension distance to define a working angle. The extension distance is within a range of extension distances that cause the working angle to be within a range of working angles that are greater than a range of working angles associated with a greater range of extension distances.

Abstract: A method for microstructuring by means of locally selective sublimation is disclosed, whereby patterns or images of organic electroluminescent components are produced by application of low molecular weight emission material, provided on a support, to those points of substrate corresponding to the pattern or image for production, by means of sublimation. According to the invention, the method is carried out by firstly completely coating a film support made from temperature-resistant material with the emission material. The coated support and the substrate are then placed adjacent and parallel to each other in a vacuum chamber. The side of the support coated with the emission material faces the substrate. The support is subsequently locally heated for a short period of time on the non-coated side thereof in those positions corresponding to the pattern or image for generation, to a temperature adequate for the sublimation of the emission material.
