Abstract
In a basic design of a developer unit for electrostatographic printing apparatus, an exit port is defined in the housing of the developer unit, for the passage of waste or surplus toner therethrough. An insert, defining a predetermined spillover barrier height and a predetermined exit angle, is associated with the exit port. Different types of inserts can be provided for operating the basic design of developer unit at different print output speeds, or with different compositions of developer material.
