20080211872 | DROPLET EJECTION APPARATUS ALIGNMENT - In one aspect, the invention features assemblies for depositing droplets on a substrate during relative motion of the assembly and the substrate along a process direction. The assemblies include a first printhead module and a second printhead module contacting the first printhead module, each of the printhead modules including a surface that includes an array of nozzles through which the printhead modules can eject fluid droplets, wherein each nozzle in the first printhead module's nozzle array is offset with respect to a corresponding nozzle in the second printhead module's nozzle array in a direction orthogonal to the process direction. | 09-04-2008 |
20080231660 | PRINTHEAD WITH INK CONDUIT WEIR FOR PRIMING CONTROL - A printhead for an inkjet printer, that has a printhead integrated circuit with an array of nozzles for ejecting ink and a support structure for mounting the printhead IC within the printer. The support structure has ink conduits for supplying the array of nozzles with ink. Within the ink conduits is a weir formation to partially obstruct ink flow so that when priming the printhead, the weir formation preferentially primes an upstream section the ink conduit. Using a weir downstream of areas that have a propensity to prime incorrectly can force them to prime more quickly or in preference to downstream sections. As long as the downstream section is one that reliably primes, albeit delayed by the weir, there is no disadvantage to priming the upstream section in preference. | 09-25-2008 |
20080231661 | PRINTHEAD WITH MENISCUS ANCHOR FOR CONTROLLED PRIMING - A printhead for an inkjet printer that has a printhead integrated circuit (IC) with an array of nozzles for ejecting ink, and a support structure for mounting the printhead IC within the printer. The support structure has ink conduits for supplying the array of nozzles with ink, the ink conduits have a meniscus anchor for pinning part of an advancing meniscus of ink to divert the advancing meniscus from a path it would otherwise take. If a printhead consistently fails to prime correctly because a meniscus pins at one or more points, then the advancing meniscus can be directed so that it does not contact these critical points. Deliberately incorporating a discontinuity into an ink conduit immediately upstream of the problem area can temporarily pin to the meniscus and skew it to one side of the conduit and away from the undesirable pinning point. Once flow has been initiated into the side branch or downstream of the undesirable pinning point, it is not necessary for the anchor to hold the ink meniscus any longer and priming can continue. | 09-25-2008 |
