Abstract

Disclosed is an alternative method of measuring copy cartridge life, independent of copy count. The method prevents overfiig of a toner waste sump and the resulting toner leakage onto copies and the components of electrophotographic printing machines. A flag having metered marks showing through a transparent window is utilized as a sump cover. As the accumulation of spent toner increases, the flag visually indicates the fullness of the toner sump. The prevention of overfidl, especially in cases where average solid area development exceeds machine capabilities, provides additional diagnostic information to a technical service representative and reduces service calls.
