Abstract
A heating device for desensitizing migration imaging film on an external imaging member scanner. The heating device is curved and has a large surface area to provide maximum heating efficiency. The heating device is mounted to a bracket connected to a scanner cartridge and moves integrally with the scanner cartridge in the direction of the longitudinal axis of the imaging member. The heating device heats the migration imaging film to a temperature to ensure that the surface charge on the film is changed, but is less than a temperature needed for selenium particle migration. As a result, the selenium in the migration imaging film is no longer sensitive under daylight conditions. Thus, the migration imaging film can be removed and heated under daylight conditions providing a significant advantage over film that must be removed and heated under red light conditions.
