A telephone messaging system with active security feature is disclosed. Accordingly, the light-emitting layer can be patterned, and a color purity and light-emitting characteristics of a full color organic polymer EL device, produced through a laser induced thermal imaging operating, can be improved. The cleaning pad is segmented by a plurality of cuts into a plurality of longitudinal sections capable of contacting the charge roller for removing the particulate from the charge roller. Devices with these improvements have numerous applications, including molecular force measurements, atomic force microscopy and manipulation technology, lithographic manufacturing, nanometer scale surface profiling and other aspects of nanotechnology.
