Abstract
A priming system for ink jet printers includes an ink tank, an ink supply line, an ink bypass line and a valving arrangement which alternately permits either pressurized ink to be supplied to a remote printhead for printing purposes or unpressurized ink to be drawn to the printhead by use of a vacuum source applied to the bypass line.
