摘要： A drag force sensor on a fountain solution carrier roller surface measures drag force of a fountain solution layer on the fountain solution carrier roller surface in real-time during a printing operation. The measured drag force is used in a feedback loop to actively control the fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

摘要： A medicament delivery product is provided in which one or more medicaments are fixed on a sheet according to a patient-specific pre-defined pattern. The sheet is formed into a three-dimensional or non-planar shape to facilitate ingestion by the patient. The pre-defined patterns for the medicaments are configured for controlled release or absorption of the corresponding medicament after ingestion by the patient. The medicaments can be in a liquid or a powder form and applied to the surface of the sheet in an appropriate manner. The one or more medicaments can be any combination of drugs, medicines, vitamins, nutritional supplements and the like.

摘要： A tone reproduction curve for a printing apparatus is periodically generated based on printed items produced by the printing apparatus. The tone reproduction curve is adjusted between periodic print-based generations of the tone reproduction curve by: determining the amount of area coverage of marking material applied by the printing apparatus during printing (in subsequent periods following an initial period in which the tone reproduction curve was generated); weighting the amount of area coverage in each of the subsequent periods differently based on how distant each of the subsequent periods is from the initial period to produce a weighted moving average of the area coverages of the marking material; and adjusting the tone reproduction curve based on the weighted moving average of the area coverages of the marking material.

摘要： An implementation of the present teachings includes inner shell for a printer, such as a liquid metal printer, that mitigates problems associated with the formation of dross. The inner shell can be installed in a reservoir of the printer during a printing process where, during the printing process, a dross can form on an interior sidewall of the inner shell. Subsequently, the inner shell can be removed and either cleaned or replaced. During printing, the inner shell can be raised and/or lowered, or otherwise repositioned, so that the dross forms over a larger surface area of the inner shell, and at a decreased thickness, compared to an inner shell that is not repositioned.

摘要： A vacuum roller system and a method of operation the vacuum roller system can include an assembly of interdigitated rollers, and a vacuum system, wherein the assembly of interdigitated rollers is operably connected to the vacuum system to move sheets of media through a downstream dryer in a printer, wherein a vacuum is drawn between individual rollers among the assembly of interdigitated rollers so that the vacuum is distributed across a sheet of media and is split around the individual rollers. The spacing between the individual rollers among the assembly of interdigitated rollers is variable to vary the vacuum.

摘要： An electronic device and a method for predicting water ingress employ a water damage indicator including a water-dispersible coating layer which includes a water-dispersible, radiation-cured polymer. Electronic components of the device, which may be susceptible to water damage, are disposed within a casing. The water damage indicator may contact the casing of the electronic device and/or the electronic components. When water enters the casing, the water dispersible coating layer is at least partially removed, revealing the surface beneath, thereby providing an indication of potential water damage to the electronic components. The water damage indicator is not readily replaceable after manufacture, making it more difficult for a customer to disguise potential water damage to the device.

摘要： A directionality detector is configured for use in an inkjet printer to attenuate the effects of ink drying in the nozzles of a printhead during printing operations. The directionality detector includes an optical sensor that generates image data of a test pattern formed on media by the printer, a diffuser that emits humidified air toward the media before the media is printed, and a controller operatively connected to the optical sensor and diffuser. The controller is configured compare the image data of the test pattern to stored image data of the test pattern printed at a previous time and determine whether any difference between the two images is greater than a predetermined threshold. The controller then operates the diffuser to direct humidified air toward the media passing the diffuser using the differences between the stored image data of the test pattern and the image data of the test pattern.

摘要： A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. A heated evaporator is connected to the cap and is adapted to evaporate an ink-compatible liquid to form a water and/or solvent vapor and supply the water and/or solvent vapor to the sealed space to protect the liquid ink in the nozzles. An insulator thermally insulates the heated evaporator from the printhead. This prevents the ink in the nozzles from drying and prevents the nozzles from clogging.

摘要： Ink stabilizing material is applied to rotatable panels within a cap of an inkjet cartridge resting structure. The rotatable panels then rotate to contact an inkjet printhead when the printhead contacts the cap. Continuous periodic flushing of the printhead is performed while the rotatable panels are contacting the printhead by periodically and repeatedly alternating between ejecting a mixture of the ink stabilizing material and ink from the nozzles, and drawing the mixture of the ink stabilizing material and the ink back into the nozzles.

摘要： A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. An evaporator is connected to the cap and is adapted to control evaporation a water-incompatible or solvent-incompatible liquid into the sealed space to condense an ink-blocking film on the surface of the liquid ink in the nozzles to protect the liquid ink in the nozzles. This prevents the ink in the nozzles from drying and prevents the nozzles from clogging.
