Abstract: The present specification discloses systems and methods for verifying facsimile numbers associated with facsimile lines. The facsimile line may be provided in a standalone facsimile machine or may be part of a multi-function device. The present specification also discloses a routine for verifying and, if required, correcting an inaccurate telephone number displayed associated with a facsimile line. The verification may be performed automatically at predefined intervals or upon receiving a prompt from a user.

Abstract: According to one aspect of the present disclosure, a print system is provided comprising a plurality of networked print engines in communication with one another, a presence detector, and a controller to communicate with the presence detector to determine a user presence and to access usage data of each of the plurality of print engines. The controller combines and shares the user presence and the usage data to adjust operations of the plurality of print engines enabling quick entry to, and quick exit from, power saving mode of at least two of the plurality of print engines.

Abstract: Disclosed are a method of controlling moisture in an electrophotographic apparatus having a fuser assembly, and corresponding electrophotographic apparatus. The method includes measuring a cavity temperature of an inner portion of the electophotographic apparatus, measuring a cavity relative humidity of an inner portion of the electophotographic apparatus, calculating a cavity dewpoint temperature using the measured cavity temperature and the measured cavity relative humidity, determining a difference between the cavity temperature and the cavity dewpoint temperature, and if the difference between the cavity temperature and the cavity dewpoint temperature drops below a predetermined threshold, turning on a heater device in the fuser assembly to control moisture in the electrophotographic apparatus.

Abstract: Systems and methods are described that facilitate calibrating a print engine using calibration data sets generated at at least two different L* levels to provide additional calibration measurement resolution toward the darker end of the grayscale spectrum. For instance a first, light grey (e.g., 70-90L*) calibration strip is scanned at a first resolution (e.g., 70-90L*) to generate a first calibration data set, and a second darker grey (e.g., 30-50L*) calibration strip is scanned at high resolution (e.g., 100L*) to generate a second calibration data set. The first calibration data set is used to calibrate the print engine for high L* values (e.g., 50-100) and the second calibration data set is used to calibrate the print engine for low L* values (e.g., 0-50). Alternatively, a single calibration strip having a known L* value can be scanned once at the known L* value and again at a higher L* value (e.g.

Abstract: A method of inducing a substrate transport fault in an image forming apparatus having a substrate transport assembly includes prompting a user to provide one or more substrate transport fault conditions, starting an image forming job, and inducing a substrate transport fault during the image forming job in accordance with the one or more fault conditions. An image forming machine is described having a substrate transport assembly for moving substrate sheets through the image forming apparatus for forming images thereon, a User Interface for prompting a user to provide one or more substrate transport fault conditions, and a controller for inducing a substrate transport fault in the image forming apparatus in accordance with the one or more substrate transport fault conditions.
