Abstract
A print engine assembly includes a support for a micro-electromechanical pagewidth print head. A single motor is controlled to dispense print media from a cartridge that is fast with the print head support and, at the same time, drive an air pump to direct air across the print head in order to keep it clear of debris. An air filter is provided to filter the air prior to it entering the air pump. The air is distributed to the print head support through a conduit that is formed in a molding which is shaped to receive the air pump.
