A fluidic dispensing device includes a housing having an exterior wall and a chamber. The exterior wall has a first opening. The chamber has an interior space and has a port coupled in fluid communication with the first opening. A stir bar is located in the chamber. The stir bar has a rotational axis. A guide portion is located in the chamber. The guide portion includes a confining member having a guide opening that defines an interior radial confining surface that engages the stir bar, wherein the guide opening facilitates a radial movement of the stir bar in a direction substantially perpendicular to the rotational axis.

Fluidic dispensing device having a moveable stir bar

A method for maintaining a fluidic dispensing device includes providing a fluidic dispensing device having a fluid reservoir containing fluid, the fluid reservoir being defined in part by a base wall, and having a stir bar located in the fluid reservoir adjacent to the base wall, and having a fluid ejection chip having a fluid ejection direction; positioning the fluidic dispensing device at a predetermined orientation, wherein the fluid ejection direction is oriented in a range of upward vertical, plus or minus 90 degrees; and rotating the stir bar in a first rotational direction starting with a first rotational speed and increasing rotational velocity from the first rotational speed to a second rotational speed.

Method of maintaining a fluidic dispensing device

A fluidic dispensing device includes a housing having an exterior wall and a fluid reservoir. The exterior wall has a chip mounting surface defining a first plane and has a first opening. The fluid reservoir is in fluid communication with the first opening. An ejection chip is mounted to the chip mounting surface. The ejection chip is in fluid communication with the first opening. The ejection chip has a plurality of ejection nozzles oriented such that a fluid ejection direction is substantially orthogonal to the first plane. A stir bar is moveably confined within the fluid reservoir. The stir bar has a plurality of paddles and a rotational axis, with each of the plurality of paddles having a free end tip that intermittently faces toward the first opening that is in fluid communication with the ejection chip as the stir bar is rotated about the rotational axis.
