ABSTRACT:
An apparatus for selectively setting the distance between the write head of an electrographic printing apparatus and a recording medium in combination with the use of a gas, present in the gap between the medium and the write head whereby the gas has a Paschen curve minimum lower than the Paschen curve for air. The combination of increasing the distance of the head from the medium along with the use of a gas as specified decreases the amount of flare while decreasing dropout and maintaining image density.
