  • Patent number: 8430472
    Abstract: In a 2M-pass printing operation that forms dots including overlapping dots, this invention makes an arrangement to ensure that the number of overlapping dots that are printed in a unit area in pairs of passes each straddling a print medium convey operation executed between an Mth pass and an (M+1)st pass is greater than the number of overlapping dots that are printed in pairs of passes straddling any other convey operation. This arrangement can cause two dots of the overlapping dots to be separated from each other in the event of a print position misalignment, preventing a possible density fall even in a unit area where the largest density reduction is feared to occur at time of the print position misalignment.

  • Patent number: 8430482
    Abstract: A micro-fluid ejection head has multiple ejection chips joined adjacently to create a lengthy array across a media to-be-imaged. The chips have fluid firing elements arranged to seamlessly stitch together fluid ejections from adjacent chips. Each chip aligns with other chips at peripheral regions having edge tolerances closer than elsewhere along the periphery. The tolerances result from both etching and dicing during chip singulation. Etching occurs at the areas of alignment. Dicing occurs elsewhere. Etching techniques include deep reactive ion etching or wet etching. It cuts a planar periphery through an entire thickness of the wafer. The etching may also occur simultaneously with etching a fluid via. Dicing techniques include blade, laser or ion beam. It cuts an entire remainder of the periphery connecting the portions already etched to free single chips from the wafer. Edge tolerances, planar shapes, dicing lines, etch patterns, and wafer layout provide still further embodiments.

  • Patent number: 8430484
    Abstract: A micro-fluid ejection head conveys fluid to firing elements at differing heights in differing layers. The ejection head includes a base substrate. The firing elements are configured on the substrate to eject fluid upon activation. Individual elements are arrayed closer or farther to a common fluid via. A multiple-layer covering on the substrate defines nozzles openings corresponding to each firing element. A lower layer of the covering directs fluid to either the closer or farther elements while a higher layer directs fluid to the other elements. The lower and higher layers define channels to direct the fluid from the fluid via. The higher layer covers the channels in the lower layer, while a topmost layer covers the channels in the higher layer. Also, the topmost layer defines the nozzle openings in large and small opening sizes. Holes in the underlying layers register with the nozzle openings, but are oppositely sized.

  • Patent number: 8430489
    Abstract: A system controls application of heat with a melt plate to an ink stick in a solid ink imaging device. The system includes a melt plate, a heater configured to heat the melt plate to a temperature sufficient to melt solid ink, a feed channel configured to direct solid ink sticks towards the melt plate to enable a leading edge of a solid ink stick to be melted by the heated melt plate, and a controller configured to separate the heater and the leading edge of the ink stick by a distance that arrest melting of the ink stick.

  • Patent number: 8430490
    Abstract: An air pump is driven to supply air via an air supply tube to a sub tank, by which a predetermined quantity of the air is mixed inside the sub tank via a gas-liquid separation membrane. Next, a carriage is swayed to agitate the ink by using the air mixed inside the sub tank. Then, the air pump is driven to discharge the air inside the sub tank via the gas-liquid separation membrane. In the above-described agitating motions, since the air utilized for the agitation is discharged from an ink tank after agitation processing, it is possible to prevent the air from remaining inside the ink tank to inflate, thereby adversely influencing the pressure relationship with a printing head.

  • Patent number: 8430491
    Abstract: A method of dynamically controlling a perceived ink color printed on a substrate can include mixing selected amounts of each of a polystyrene nano-sphere dopant component and a nano-particle dopant component with a clear fluid carrier component, the mixed components configured in real time to define an ink structure having a predetermined wavelength. The method can further include imaging the substrate by ejecting the mixed components onto the substrate, the perceived color of the imaged substrate corresponding to a reflected wavelength of the ink structure. In embodiments, each of the carrier and dopant components can be in a powder form suitable for fuser type imaging devices.

    Abstract: An ink forming method involves preparing a deagglomerated ink or a modified deagglomerated ink. The deagglomerated ink or the modified deagglomerated ink includes at least deagglomerated colorant particles and a liquid component. The deagglomerated colorant particles are chosen from pigment particles each encapsulated with a dispersant. The colorant particles have a particle size ranging from about 50 nm to about 500 nm. Prior to shipping and/or storing the deagglomerated ink or the modified deagglomerated ink, a portion of the liquid component is removed to form a concentrated ink that has a nonvolatile solids content ranging from about 40 wt % to about 90 wt % of the concentrated ink.
