Abstract

In order to produce high quality copies, a sequential screen 10 may be employed in an electrophotographic printing machine0 Frequently, screen 10 is positioned between the exposure system 12 and the development system l4~ Screen 10 is located closely adjacent to the photo~ conductive surface of drum l6~ Screen 10 is highly sensitive to dirt and must be kept substantially free from contaminants0 Air flow passes under screen 10 from developer unit 12 carrying toner particles therewith0 To prevent these toner particles from being deposited on screen 10, an air purge deflector 18 is interposed between screen 10 and the developer unit 14. Deflector 18 allows relatively clean air to be drawn, from above, across the lower surface of screen 10 protecting it from toner laden flow.
