Abstract

The elimination of parts in a reprographic or similar imaging machine is necessary to improve reliability and reduce the costs of such machines. The present disclosure is directed to an improved exposure lamp, 12, which is depicted in the figure. Lamp 12 is essentially a fluorescent exposure lamp of the type that is commonly used in reprographic and scanning systems to illuminate a document. However, the present lamp design further includes an opaque paint or similar covering, 14, that is applied directly to the outside of the lamp to prevent light from esca ing everywhere except for a clear or
