Abstract: A multi-function device (MFD) is disclosed. For example, the MFD includes a local communication interface, a proximity sensor to detect a user within a detection range, a processor, and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include detecting the user within the detection range via the proximity sensor, scanning a mobile device of the user for a device identification via the local communication interface, determining that the device identification is associated with the user that is authorized on the MFD, and automatically logging the user into the MFD.

Abstract: A printer and method of operating the printer adjusts firing signal waveforms for inkjets that eject at least one ink drop into one or more ink images produced by the printer to reduce the ink drop variability of the ink drops ejected into the one or more images. A range of acceptable ink drop volumes is identified using a nominal ink drop volume and a maximum ink drop volume deviation. The firing signals for the inkjets outside of this identified range are adjusted to shift the ink drops ejected by these inkjets into the range of acceptable ink drop volumes.

Abstract: An inkjet printer prints on a first side of a media sheet less than all of the color separations in an image, generates a first set of image data of the printed color separations to identify image features, returns the partially printed media sheet to a position that precedes the print zone in the printer, generates a second set of image data of the partially printed media sheet before it reenters the print zone to identify the image features, compares the positions of the image features in the first set of image data to the positions of the image features in the second set of image data to register one or more color separations remaining to be printed with the color separations printed on the first side of the media sheet, and prints the remaining registered color separations on the first side of the partially printed media sheet.

Abstract: A method of making thermoplastic polymer particles may include mixing in an extruder a mixture comprising a thermoplastic polymer and a carrier fluid that is immiscible with the thermoplastic polymer at a temperature greater than a melting point or softening temperature of the thermoplastic polymer and at a shear rate sufficiently high to disperse the thermoplastic polymer in the carrier fluid; cooling the mixture to below the melting point or softening temperature of the thermoplastic polymer to form solidified particles comprising thermoplastic polymer particles having a circularity of 0.90 or greater and that comprise the thermoplastic polymer; and separating the solidified particles from the carrier fluid.

Abstract: A method and system for rendering a watermark with near perfect infrared colors can involve providing an infrared pattern ink having a color with a lower spectral reflectance in an infrared spectrum, replacing the color having the lower spectral reflectance with a replacement color constituting a combination of colors having a higher spectral reflectance in the infrared spectrum, them matching in a visible spectrum, the replacement color with the color having the lower spectral reflectance in the infrared spectrum, and rendering a watermark as a metameric color pair including the infrared pattern ink and replacement color. Alternatively, a watermark may be created by defining a first color pattern having a CMYK value derived from a particular LAB value with a lower toner stack and a higher reflectance in an infrared spectrum as compared to a second color pattern having a second CMYK value derived from the same LAB value.

Abstract: The present disclosure discloses methods and systems for detecting one or more security patterns in a document submitted at a multi-function device. According to the disclosure the document is received at the multi-function device, wherein the document includes at least textual content. Thereafter, a pre-defined operation is performed to detect edges of the at least textual content. Once detected, one or more text edges are filtered based on one or more templates. Further, based on the one or more templates, shape and color of the filtered one or more text edges are analyzed, and accordingly, the presence of the one or more security patterns is ascertained in the submitted document at the multi-function device.

Abstract: A method of inkjet printer operation identifies a problem with an inkjet printer using a comparison of an index for a printhead map identifying inoperative inkjets in a printhead with indexes for clusters of extracted feature descriptors corresponding to printhead maps for printheads having inoperative inkjets stored in a dictionary in a database operatively connected to a controller in the inkjet printer. The dictionary is developed using unsupervised cluster analysis of datasets comprised of printhead maps identifying inoperative inkjets in a plurality of printheads.
