Abstract: A radiant energy ink drying device for drying ink on paper exiting a printer includes a lightbox, cooling fans for cooling the light box, and a processing unit. The processing unit controls the operation of the cooling fans based on signals received from a temperature sensor located in the drying area of the lightbox. The processing unit also deactivates the printer based on signals from a paper sensor located on the light box. In addition, an overtemperature sensor deactivates the printer when the light box housing exceeds a predetermined temperature.
