ABSTRACT:
A baffle assembly for insertion into an ink supply reservoir includes a first baffle plate having a first end and a second end, wherein a first end plate is coupled to the first end of the first baffle plate and a second end plate is coupled to the second end of the first baffle plate. The first baffle plate, the first end plate, and the second end plate form an integral structure. When the baffle assembly is inserted into the ink supply reservoir, a distance, "b", between the first baffle plate and an adjacent side-wall of the ink supply reservoir satisfies the inequality relationship b<(g/a)Dm/2k, wherein "g" is the local acceleration of gravity; "a" is the acceleration experienced by the ink supply reservoir during a change in a travel direction, "Dm" is the change in an ejected ink drop mass due to a change in an ink reservoir pressure in the ink supply reservoir, and "k" is a slope of the ink drop mass versus the ink reservoir pressure. The baffle assembly loosely divides a volume of the ink supply reservoir into a plurality of smaller compartments. An ink flow between the plurality of compartments may be provided by a gap between the baffle plates and the floor of the ink supply reservoir.
