ABSTRACT:
An environmental control for a charger utilized in an electrostatographic reproduction apparatus including a movable dielectric support upon which images of information to be reproduced are formed as the dielectric support is moved into operative relation with electrostatic process stations. The charger environmental control system as disclosed includes a housing associated with charger. The housing is selectively provided with a positive pressure air flow or a negative pressure air flow. The positive pressure air flow and the negative pressure air flow are controlled such that during movement of the dielectric support of the reproduction apparatus, positive pressure air flow is provided to the housing, and when such dielectric support is at rest, negative pressure air flow is provided to the housing.
