Abstract
An ink jet printer has a body with a paper path and a carriage operable to reciprocate across the paper path. An ink supply receptacle on the body is spaced apart from the carriage, and an ink conduit extends between the ink supply receptacle and a fluid output interconnect on the carriage. A gas release facility connected to the conduit allows air to be released from the conduit when the printer is first to be used. This may occur in response to filling the conduit with ink, and the facility may be near the carriage end of the conduit to allow substantial evacuation of air from the conduit. The facility may prevent further release of gas or fluid when wet, such as provided by a porous polymer material.
