Title: SELF-PRIMING INK SYSTEM FOR INK JET PRINTERS
Abstract:
A priming system for ink jet printers includes a pressurized ink tank (12), an ink supply line (14), an ink bypass line (18) and a valving arrangement (30, 31) which alternately permits either pressurized ink to be supplied to a remote printhead for printing purposes or unpressurized ink to be drawn from the printhead by use of a vacuum source (55) applied to the bypass line (18).
