Patent ID: 8655217

Claim:
A method for controlling airflow across a width of a charger support area having a charger housing supporting a corona charger that is proximate to a primary imaging member, comprising: providing a flow of air proximate an inlet side of a charger housing area; and using a deflection surface to deflect the flow of air from a first direction to a second direction leading to an impact surface against which the flow of air is disbursed; wherein the impact surface is outside of a width of the charger housing and the primary imaging member so that the air flow can supply a volume of disbursed air into the charger housing area that is sufficient to create a pressure that causes the disbursed air to move to an outlet on an opposite side of the charger housing area without directly exposing the charger or the primary imaging member; and wherein the disbursed air moves from the impact surface to the outlet at a rate that is insufficient to entrain airborne particles that could cause damage to the charger or to the primary imaging member.
