Abstract

1428799 Light baffle XEROX CORP 4 May 1973 [5 May 1972] 21262/73 Heading G2H To prevent fogging of photo-conductive drum 10 by light from flash fuser 100, a copy member such as web 12 is passed through a light baffle 200, consisting of a housing with light-absorbing interior surfaces and light-blocking means within the housing to prevent light which enters the housing through its outlet from reaching the inlet. The web changes direction around a part of lightblocking means. Alternatively the copy member may be a sheet. Similar light baffles may be used in other environments in which a material is to be passed between a light sensitive station and a light emitting station.
