Abstract
A method of processing documents involving: transporting the documents at high speed along a prescribed transport path past at least one image-lift site; scanning the entirety of respective document faces at the sites; providing an energy-shaping ate, disposed at each of the sites and acting to channel the imaging illumination energy there; and providing a heat-dissipation stage acting to extract infra-red energy therefrom and dissipate it so as to shield the sites; this heat-dissipation stage comprising an infra-red extraction unit that includes a selective reflector interrupting the beam path and adapted to divert infra-red energy as an infra-red beam along a second path; and an associated infra-red dissipation unit including multi-blade surface; disposed within an enclosure, adapted to receive the infra-red beams and to trap them and convert them to surface heat.
