Abstract
A printer valve assembly including a plurality of valves. Each of the valves is actuated between an open state which permits fluid flow though the valve and a closed state which prevents fluid flow though the valve. The plurality of valves includes a first feed valve, a first return valve, a waste valve and a purge valve. The first feed valve controls flow between a source of first print fluid and a feed line to a print head. The first return valve controls flow between a return line from a print head and a source of first print fluid. The waste valve controls flow between a return line from a print head to a waste receiver. The purge valve controls flow between a source of purge fluid and a feed line. The printer valve assembly further includes a valve control member which is mechanically connected to the valves to simultaneously control the state of the valves based on a position of the valve control member.
