Abstract: A method and a diagnostic device for a printing press are described, wherein data is automatically transmitted by a central data processor of the printing press to a locally distanced central data processor when a threshold value is upwardly transgressed, downwardly transgressed or reached.

Abstract: An apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head is designed to cheaply and easily permit substantially reliable positioning. In the apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head, in which apparatus the image carrier is mounted so as to be rotatable around its longitudinal axis, the image carrier can be swiveled around an axis perpendicular to the longitudinal axis. The invention can be applied to devices that generate images and to devices that reproduce images, in particular for the production of type forms and for the scanning of originals.
