Radiation fixing device with natural convection airflow

摘要

A radiation fixing device for fixing a powder image on a sheet with the aid of heat-radiating lamellae which extend on both sides of a horizontal sheet conveyor path, the heat-radiating lamellae being situated in a housing having slot-shaped openings through which a sheet is fed into and led out of the housing. Air flow openings are provided in the base of the housing for automatically activating an air flow through the housing by means of natural convection, in areas adjacent to a sheet moving through the housing.
