Abstract
The present invention is directed to an ink supply device for use in an ink jet printer having a constant flow rate pump for ink supply. Preferably, the ink supply pressure at an ink ejection nozzle is sensed and as a result of this ink and an ink solvent are alternatively fed, thus supplying ink of a fixed viscosity to the ink ejection nozzle.
