Methods and systems for inserting and replacing swaged probe pins in a lower die portion of a head having an array of micro-holes for receiving the probe pins are disclosed. The methods and systems include the following: swaged probe pins including substantially cylindrical ends and a swaged center portion; and an assembly aid film including an array of slotted holes, each of the slotted holes including a substantially round portion for receiving the substantially cylindrical ends of the swaged probe pins and slot portions for receiving the swaged center portion of the swaged probe pins. The array of slotted holes is configured to properly align the swaged probe pins with the array of micro-holes.

Die design with integrated assembly aid

An ink supply comprises an ink container having an opening for releasing ink and a valve member and a mechanism for biasing the valve member so as to prevent the flow of ink from the container when the ink supply is not mounted on a supply base. The ink jet system includes an ink reservoir, a cover enclosing the reservoir, and a neck having a threaded inner surface engaging the ink supply when the ink supply is inserted within a first opening within the neck The cover has a second opening that is concentric with and below the neck and the first opening to permit ink to flow from the ink supply, through the second opening and into the reservoir. A flat shoulder of the cover surrounds the second opening and controls the ink supply by stopping further insertion once the ink supply is fully mounted,

INK SUPPLY FOR IMPULSE INK JET SYSTEM, SAID INK SUPPLY INCLUDING A CAP HAVING THREADED PERIPHERY, AND A VALVE SUPPORTED BY THE CAP, WHEREIN A PROJECTION EXTENDS FROM A SURFACE OF THE CAP INTO AN INK RESERVOIR

An ink supply apparatus includes a container for storing ink jet ink having an opening for releasing ink from the container, a valve member mounted in the opening in the container, and a mechanism coupled to the valve member for biasing the valve member so as to prevent the flow of ink from the container when the ink supply is not mounted on a supply base

Ink supply for impulse ink jet system, said ink supply including a cap having threaded periphery, and a valve supported by the cap, wherein a projection extends from a surface of the cap into an ink reservoir

A dense array of ink jets is achieved by a fanning-in of chambers to a linear array of orifices. The ends of the chambers remote from the orifices have actuation locations which are coupled to elongated transducers having axes of elongation which are parallel to the axes of ejection of droplets from the orifices.

Apparatus for printing with ink jet chambers utilizing a plurality of orifices

An impulse fluid jet apparatus having pulse generating circuitry for an impulse jet. The circuitry generates driving a longer pulse exciting the resonant frequency of the jet and a shorter pulse for exciting a higher harmonic frequency of the jet. The longer pulse changes the state of energization of the transducer in the jet to eject a droplet of fluid and the shorter pulse changes the state of energization so as to break off the tail of the droplet.

Method for increasing the throw distance and velocity for an impulse ink

An ink supply system for an impulse ink jet apparatus includes a hand held peristaltic device for priming. Ink is supplied by a removable container by gravity feed through a valve mechanism.

Ink jet chambers of an array of ink jet devices extend laterally outwardly from a linear array of elongated transducers. This configuration creates two sets of linear arrayed orifices utilizing a single linear array of transducers so as to provide large field, high density printing for use in, for example, printing bar codes.

Ink jet apparatus having a plurality of chambers with multiple orifices

An ink supply apparatus comprises a container for storing ink jet ink having an opening for releasing ink from the container and a valve member mounted in the opening in the container and spring means coupled to the valve member for biasing the valve member so as to prevent the flow of ink from the container when the ink supply is not mounted on a supply base.

Ink jet ink supply apparatus

Impulse ink jet apparatus has a plurality of side-by-side chambers extending along a line that is slanted with respect to a direction of scanning relative to a recording medium. Each of the chambers includes a plurality of orifices that are arranged along a line extending substantially transverse to the scanning direction and a transducer for ejecting a plurality of droplets from the orifices of each chamber. The orifices are formed upon an orifice plate such that the distance between the centers of adjacent orifices associated with a single chamber are separated by a predetermined distance greater than the center distance required for drop placement on the recording medium.
