A method of filling an ink supply bag with a liquid ink comprises flowing the liquid ink from an orifice in a nozzle extending deep into the bag and at an initial delivery velocity that is low enough to substantially prevent bubbles from forming in the delivered liquid in the bag in order to prevent the liquid ink from foaming, and after the liquid level in the bag rises to immerse at least the orifice increasing the delivery velocity to speed up the fill rate for the bag.

Method of filling ink supply bag for ink cartridge

An ink composition and an ink cartridge having the ink composition are provided. The ink composition includes a colorant and an aqueous carrier. The ink composition has a dissolved gas content of less than 3 ppm as measured on the basis of the amount of dissolved oxygen gas at 20&deg; C. at 20&deg; C., a static surface tension at 25&deg; C. of greater than 34 dynes/cm, and an advancing contact angle relative to an ink receiving receiver of less than about 55&deg; at room temperature. The ink container can be a collapsible bag.

Ink composition, ink cartridge having ink composition, and method of filling ink cartridge

A method for filling and degassing a pouch contained in a cartridge. A fluid injection unit introduces fluid into a rotatable pouch. The pouch contained in the cartridge is permitted to rotate from a vertical position for degassing and weighing to a horizontal position for fluid introduction. After several rotational cycles, accurate pouch weighing and complete evacuation of the pouch results in a precise fluid loaded pouch.

Method of accurately filling and degassing a pouch

An apparatus precisely delivers a prescribed amount of fluid into a degassed pouch contained in a cartridge. The apparatus has a rotating cartridge holding member that alternately positions the cartridge in either a horizontal position for filling or a vertical position for degassing. A digital weighing element associated with the fixture enables the cartridge to be weighed during the filling process to ensure the delivery of a predetermined amount of fluid.
