Abstract
Method and apparatus for preventing dust, which developes in document handling machines, from accumulating in the orifices of associated ink jet printers and clogging them, includes disrupting the path of dust laden air to prevent it from flowing near the orifices where dust would be deposited. In a preferred embodiment, a counterflow of air from a fan is directed against the dust laden air to disrupt its flow and cause the dust to be carried away from the orifices.
