A bulk ink feed system for an inkjet printer comprising a plurality of reservoirs coupled by a plurality of conduits through a plurality of inlet connectors on an ink cartridge carrier of an inkjet printer. The plurality of conduits contain an accumulator section adjacent the coupler. The accumulator section has a larger volume than the remainder of the conduit, which inhibits the reverse flow of ink from the accumulator section toward the reservoir section when the inkjet printer is not in use.
