delivery hoses 78 are connected to respective connectors 76 that extend from the upper plate 71 due to the inherent flexibility of the extrusion 15 it can contort into many ink connection mounting configurations without restricting ink and air flow the molded end cap 70 has a spine 73 from which the upper and lower plates are integrally hinged the spine 73 includes a row of plugs 74 that are received within the ends of the respective flow passages of the extrusion 15 the other end of the extrusion 15 is capped with simple plugs which block the channels in a similar way as the plugs 74 on spine 17 the end cap 70 clamps onto the ink extrusion 15 by way of snap engagement tabs 77 once assembled with the delivery hoses 78 ink and air can be received from ink reservoirs and an air pump possibly with filtration means the end cap 70 can be connected to either end of the extrusion ie at either end of the printhead the plugs 74 are pushed into the channels of the extrusion 15 and the plates 71 and 72 are folded over the snap engagement tabs 77 clamp the molding and prevent it from slipping off the extrusion as the plates are snapped together they form a sealed collar arrangement around the end of the extrusion instead of providing individual hoses 78 pushed onto the connectors 76 the molding 70 might interface directly with an ink cartridge a sealing pin arrangement can also be applied to this.
