ABSTRACT:
An automatic start-up sequence is provided for an inkjet printer that uses volatile inks for printing. At startup, colorless flush fluid is employed to remove in the drop generator and from the exterior of the orifice plate and from the charge plate. Jets of the flush fluid are established. Stimulation is applied to the jets and charge voltage is applied to the associated charging electrodes to deflect the jets toward the catcher. Concurrent with the jets being so deflected, the jetting fluid is changed from flush fluid for cleaning to the ink for printing. The ability to control the jets of fluid with charge voltage prevents splattering of fluid on the charge leads during the transition from make-up fluid to ink.
