Abstract
A method and system for reducing or eliminating banding in a rendering device caused by pressure pulsations from a blower. The pressure pulsation frequency resulting from a plurality of pressure pulsations propagated from a blower can be reduced by forming an obstruction device at an outlet of the blower. Total airflow and total pressure propagated by the blower are maintained by modifying or removing an existing restrictor plate thereby reducing acoustic noise associated with the pressure pulsations in a xerographic cavity.
