Abstract

An apparatus is used with an ink jet print head in an ink jet printer. The apparatus includes a print head protector that surrounds a print head. A substantially continuous slot is provided along a perimeter of the bracket and a filter is located in the substantially continuous slot. An inlet in fluid communication with the substantially continuous slot enables a positive pressure air supply to be coupled to the inlet. The air entering the inlet flows through the filter in the slot and the filtered air flows outwardly away from the print head.
