Abstract: Techniques manage log data. Such techniques involve receiving log data describing a state of an application system at a target time point. Such techniques further involve determining whether a level of the log data satisfies a predetermined level. Such techniques further involve, in response to determining that the level of the log data satisfies the predetermined level, storing log data within a predetermined range adjacent to the target time point to a log repository of the application system, the predetermined range indicating the amount of log data expected to be stored.

Abstract: A coefficient of friction (COF) sensor on a carrier roll surface wetted with fountain solution transferred from an imaging member measures COF of the wetted carrier roll surface in real-time, even between or during printing operations. The transferred fountain solution may be concentrated and/or chilled to solidify before the measurement. The measured COF 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 an imaging or other printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

Abstract: A method of operating a printer supplies an ink solvent or mixture of ink solvents to porous members positioned adjacent printheads. The ink solvent or solvent mixture evaporates from the porous members to provide a solvent vapor environment in the vicinity of the nozzle plates of the printheads. The solvent vapor environment attenuates the evaporation of ink solvent from ink drops on the nozzle plates or from the ink in the nozzles of the printheads. Thus, the ink on the nozzle plates and in the nozzles does not dry out and the operational status of the inkjets is preserved.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a magnetic field generator to form a magnetic field selectively about a nozzle from which melted metal drops are ejected. The drops ejected in the presence of the magnetic field have their velocities reduced from the initial velocity at which they are ejected. The reduced velocity increases the time in flight of the drops before they impact their landing areas. The increased travel time enables the melted metal drops to oxidize sufficiently that they bond less tightly than the drops ejected without passing through the magnetic field. Thus, the apparatus can form metal support structures that adhere less tightly to the part portions of the object so they can be more easily removed after printing of the object.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is configured to eject melted metal drops from an ejector head at different velocities to form different portions of metal object layers with different measurable values of a same physical property. The different velocities are achieved by operating the ejector head with two different electrical voltages. The greater voltage that achieves the higher velocity is about 25% greater than the voltage used to achieve the lesser velocity. By operating the ejector head with the two different voltages different portions of the object can be formed with different physical property characteristics.
