    Abstract: An inkjet printer includes a waste ink treatment system and a humidification chamber to separate waste ink produced by a printhead maintenance station into solid ink pigment particles and a solvent stream and use the solvent stream to maintain inkjets in the printheads of the inkjet printer in operational status. The waste ink treatment system mixes the waste ink with a metal salt to precipitate the solid ink pigment particles out of the waste ink. The solvent stream remaining after the precipitation of the pigment particles is humidified and directed to air baffles positioned on opposite sides of each printhead in every other printhead module in the process direction. A kit is provided to retroactively modify an existing inkjet printer to treat the waste ink and use the solvent stream to maintain the operational status of the inkjets in the printheads of the inkjet printer.

    Abstract: A multi-function device (MFD) is disclosed. For example, the MFD includes, a communications interface to establish a communication session with other MFDs within a community of MFDs, a processor, and a non-transitory computer readable medium storing instructions, which when executed by the processor, cause the processor to detect an undesirable image quality level of a print job, determine an optimal setting MFD in the community of MFDs, request optimal settings from the optimal setting MFD, receive the optimal settings from the optimal setting MFD, configure settings on the MFD in accordance with the optimal settings, and execute the print job with the optimal settings.

    Abstract: Systems and methods for verifying the authenticity of a printed document are disclosed. The methods include receiving an identification of a portion of the printed document that includes a document signature, and receiving a document signature corresponding to the printed document from a data store. The document signature includes images of one or more first satellite droplet patterns (SDPs) that each include a plurality of ink satellite droplets that were randomly formed during printing of a print image on the printed document. The methods further include receiving an image of the portion of the printed document, analyzing the image to identify one or more second SDPs in the printed document, and authenticating the printed document by determining whether at least some the one or more first SDPs match a corresponding one or more second SDPs.

    Abstract: Methods and systems for defining characters, can involve selectively removing pixels from one or more characters and rendering a character with a user space equivalent to a device space. Multiple abutting non-line pixels can be removed among the pixels from the character(s). Furthermore, the character(s) including the multiple abutting non-line pixels as expected for the character(s) can be created prior to prior to selectively removing the pixels from the character(s). This approach can avoid partially marked pixels by setting user space equal to device space and then selectively removing pixels when printing microtext. Selective pixel removal allows for more white space and better recognition of characters such as, for example, “8” and “E”.

    Abstract: A security apparatus, method and system for rendering a security mark, can involve providing a security mark with a metameric pair of infrared inks. A spectral reflectance of two metameric inks among the metameric pair of inks differs for CMYK for K in infrared. A first metameric ink among the metameric pair of infrared inks can be configured to include more K than a second metameric ink among the metameric pair of infrared inks, wherein when a document containing the security mark is scanned, and the number of K pixels in the first metameric ink is filtered to destroy the security mark when viewed through an infrared camera.

    Abstract: An inkjet printer includes air baffles on opposite sides of each printhead in the process direction. The air baffle on the upstream side of the printheads directs a positive air flow toward a conveyor moving media past the printheads and the air baffle on the downstream side pulls a negative air flow on the opposite side. The positive and negative air flows produce an air flow across the nozzle plates of the printheads that sweep all of the ink drops of a sneeze pattern and satellite ink drops produced from the sneeze pattern ink drops into the air baffle pulling the negative air flow. A kit is provided to retroactively modify an existing inkjet printer to produce an air flow that sweeps the nozzle plate of a printhead between the air baffles of the kit.

    Abstract: Apparatuses have a processing device that is operable with a connection to a physical cryptographic key device that has a valid cryptographic key. Such devices further include a connector that is adapted to connect to the physical cryptographic key device. The processing device is operatively connected to the connector. The processing device is adapted to change available functionality based on connection to, and disconnection from, the physical cryptographic key device.
