Heat radiator exchange appts. for heating rollers of fixing unit - uses central opening in bearing for insertion and removal of radiating module for electrophotographic copier or printer

摘要

The heat radiator is assembled to form a cylindrical radiator module which can be inserted in the heating rollers (11) mounted in the electrophotographic copier or printer via guides. The inner space of the heating rollers is accessible at least from one side. One end of the module has a receptor for a heat-insulated handle. The latter is formed as a centring and holding element for the module. The roller is mounted on at least one element having a central through opening formed as a centring and guide element for the radiation module. A spacer is assigned to one mounting element also having a through opening as a centring and holding element for the module. ADVANTAGE - Simple exchange of heat radiator without use of tools or extension of rollers, including while appts. is still hot.
