An ink system for use in an inkjet printing apparatus includes an inkjet printhead, a supply subtank for containing a supply of an ink to the inkjet printhead, and a return subtank for containing a surplus of the ink not used by the inkjet printhead. A first fluid path couples the supply subtank with the inkjet printhead and with the return subtank, and provides a flow of ink from the supply subtank to the inkjet printhead and to the return subtank. A second fluid path couples the return subtank with the supply subtank and feeds the ink from the return subtank back to the supply subtank. The ink system is characterised by having the supply subtank, the return subtank and the first fluid path supported on a carriage for reciprocating together with the inkjet printhead across the printing medium.
