    Abstract: A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes detecting use of the MFD, wherein the MFD is associated with a plurality of MFDs that are designated as a cluster within a location, deactivating the MFD in response to use of the MFD being detected, transmitting a first notification to deactivate the plurality of MFDs within the cluster in response to use of the MFD being detected, initiating a decontamination process within the location in response to the use of the MFD being detected, receiving an indication that the decontamination process is completed, transmitting a second notification to reactivate the plurality of MFDs within the cluster, and reactivating the MFD.

    Abstract: A system generates a secure barcode and prints the secure barcode on a substrate. The barcode includes a first set of cells of a first color and a second set of cells of the second color. A first vector pattern is encoded onto pixels for first set of cells of the barcode, and a second vector pattern is encoded onto pixels that correspond to the set group of cells of the barcode. The vectors in each pattern will have substantially the same colors, thicknesses and frequencies, but will be out of phase with respect to each other. The system will generate a secure barcode that vectors of each pattern.

    Abstract: A method for sorting a group of managed devices includes querying a database of managed device with a sort query, such as an SQL query. The sort query captures an initial adjacency list in which managed devices are ordered, based on their respective parent device. Each of the managed devices is associated with a set of attributes. The initial adjacency list is sorted, e.g., using a depth-first search, based on at least one sorting criterion to generate a sorted adjacency list in which managed devices having a common parent device are reordered, based on respective attributes. The sorted adjacency list can be represented as a sorted directed graph, such as a directed tree. Modifications can be made to the sorted directed graph. A visualization of the sorted and optionally modified directed graph is output and/or a file is distributed to at least some of the managed devices, based thereon.

    Abstract: A user interface of a printer displays instructions to use the printer's document scanner for scanning a sheet of print media (of a stack of print media being added to the paper drawer) in response to a drawer sensor detecting the opening of the paper drawer. The document scanner generates an electronic image of the sheet of print media from the scanning of the sheet of print media. The processor evaluates the electronic image of the sheet of print media to identify the media type and color of the stack of print media being added to the paper drawer. For example, this is done by evaluating the size, color characteristic, transparency, and reflection characteristic of the electronic image of the sheet of print media. Then, the electronic memory records that the paper drawer contains the stack of print media having a specific media type and color.

    Abstract: A method and system assist a user in selecting a print option for rendering an image. A database includes print options for rendering images on different sizes of print media. At least some of the print options include different levels of scaling of the image. Features of an image to be rendered are identified. Based on the identified features, at least one of the following is performed: filtering the print options and ranking the print options in the database, to identify a subset of candidate print options from the database of print options. A graphical user interface is generated for displaying representations of at least some of the candidate print options. The graphical user interface is displayed to a user on a display device, whereby a user is able to select a print option for rendering the image.
