Abstract

In electrophotographic printing machines, the developer mix frequently comprises conductive carrier. Conductive carrier will produce a short circuit between the developer roll and the developer housing when the developer housing is tempor-arily positioned in an inoperative location, This may be prevented by electrically biasing the photoconductive drum relative to ground rather than with respect to the developer roll. In this way, the developer roll and the developer housing are at substantially the same potential and a short circuit will not develop. A system of this type will require the adjustment of the grid screen and shield potentials of the corona generating devices employed in the printing machine,

In electrophotographic printing machines, the developer mix
frequently comprises conductive carrier. Conductive carrier
will produce a short circuit between the developer roll and
the developer housing when the developer housing is tempor~
arily positioned in an inoperative location, This may be
prevented by electrically biasing the photoconductive drum
relative to ground rather than with respect to the developer
roll. In this way, the developer roll and the developer
housing are at substantially the same potential and a short
circuit will not develop. A system of this type will require
the adjustment of the grid screen and shield potentials of the
corona generating devices employed in the printing machine,
