Abstract
A replaceable ink supply tank that can be mounted to a pen body of a printhead system for use with an ink jet printer. The ink supply tank provides the necessary back pressure for successful operation of the printhead and includes a siphon break in the conduit that supplies ink from the supply tank to the pen body. A conduit connects the ink supply tank to the pen body. The conduit contains a raised portion that is at a level higher than the ink level in the supply tank. The conduit contains a siphon break chamber between the raised portion and the pen body. The conduit further contains an accumulator in the raised portion of the supply tank. The accumulator maintains back pressure in the preferred range to discourage drooling from the nozzle plate during ambient temperature swings.
