摘要： Inkjet printhead with an array of ejection chambers spaced in an array direction, each communicating with an ink orifice, inlet and outlet plenum chambers communicating with the ejection chambers, and inlet and outlet manifolds extending in the array direction and communicating with the plenum chambers through a porous sheet. While there are substantial net ink flows in the array direction in the inlet and the outlet manifolds, there is substantially no net flow in the array direction in the inlet or outlet plenum chamber. Ink pressure is therefore constant over the array of ejection chambers.

摘要： A hollow cylindrical support for a plurality of flow-through inkjet print heads has two folded wall sections cooperating to define elongate inlet and outlet ink manifolds, one wall section being thermally conducting so as to promote heat transfer along the length of the support, the other wall section being thermally insulating so as to inhibit heat transfer between the inlet and outlet manifolds. The thermally insulating section serves to trap a boundary layer of fluid, for example in a cavity wall or cellular material.

摘要： A nozzle plate component manufactured by forming a layer of photoresist on a substrate and selectively exposing and removing material to define an array of distinct bodies. Nickel is then electroformed around the bodies to form a plate, with nozzles subsequently formed by ablation through the photoresist. The process can essentially be repeated to form a guard structure around each nozzle.

摘要： Droplet deposition apparatus comprises an array of fluid chambers, each chamber communicating with an orifice for droplet ejection, a common fluid inlet manifold and a common fluid outlet manifold, and means for generating a fluid flow into the inlet manifold, through each chamber in the array and into the outlet manifold, the fluid flow through each chamber being sufficient to prevent foreign bodies in the fluid from lodging in the orifice. Each chamber is associated with means for effecting droplet ejection from the orifice simultaneously with the fluid flow through the chamber. The resistance to flow of one of the inlet and outlet manifolds is chosen such that the pressure at a fluid inlet to any chamber in the array varies between any two chambers by an amount less than that which would give rise to significant differences in droplet ejection properties between these two chambers.

摘要： A nozzle in a nozzle plate for an inkjet printhead is formed by directing a laser beam at a nozzle plate. Accurate control of the divergence of the beam is achieved by splitting the beam into sub-beams, each sub-beam having divergence with an origin lying apart from the point at which the beam is created by splitting, and thereafter recombining the sub-beams. Greater accuracy in the taper and inlet shape of the manufactured nozzle is thereby obtained.

摘要： Ink jet printer dispersion inks are provided which contain a dispersant having basic or acid groups and a non-destabilizing amount of a neutralizer for said groups. The inks exhibit improved non-wetting characteristics leading to lengthening of the duration of periods of continuous printing that can be achieved before cleaning or replacement of the nozzle plate of the ink jet print head is required.

摘要： An inkjet printhead comprises an array of parallel channels separated one from the next by side walls transversely displaceable in response to an actuating signal. Pattern dependent crosstalk is avoided by applying to a channel selected for actuation a signal held at a given non-zero level for a period of length greater than that the length of the period at which the velocity of droplets ejected from said channel is at its maximum and at which the velocity of a droplet ejected from said selected channel is substantially independent of whether or not channels in the vicinity of said selected channel are similarly actuated to effect droplet ejection simultaneously with droplet ejection from the selected channel.

摘要： In a method of making an ink jet printhead, corrugations are formed by laser ablation in the bonding surface of a polymer nozzle plate. Adhesive is applied to the micro-cavities thus formed and the nozzle plate is pressed against the end surface of the printhead until the surface lands in the nozzle plate abut on the surface of the printhead.
