ABSTRACT:
Multi-color ink-jet pens having an orifice set associated with each color are primed by an apparatus that avoids mixing of two colors during priming. A resilient seal forms a chamber that encloses the orifice sets. The chamber is connected to a vacuum source to reduce the pressure in the chamber for drawing ink out of the orifices. A set of suction tubes connects to the vacuum source, with each tube terminating within the chamber in closely spaced relation with a corresponding orifice set for drawing excess ink away from the orifice set, thereby preventing the various colors of primed ink from mixing.
