A method of determining a media class using an optical translucence sensor (OTS) in an imaging device. A media sheet for processing by a media processing device (MPD) in the imaging device passes through an OTS positioned on a media path prior to the MPD. The OTS has an output that is periodically sampled in several predefined interest zones to provide a plurality of intrinsic variables related to the media sheet. The intrinsic variables are combined with extrinsic variables to form a variables data set that is normalized then fed to a controller having a predefined set of media class determining equations for determining a media class for the media sheet. A media class determining equation is provided for each class of media expected to be used in the imaging device. The determined media class is then used to set one or more operating parameters for the media processing device.

Method of determining a media class in an imaging device using an optical translucence sensor

An operational imaging device and method using a predetermined set of operating parameter determining (OPD) equations forming an OPD equation set for providing one or more operational parameter values for processing of a media sheet. The OPD equation set, stored in the operational imaging device, is solved using values for a set of N variables measured by an operational sensor set in the operational imaging device. Each equation solution determines a value for one of the operating parameters. The OPD equation set is generated by a training system using a continuum training engine. A training data set containing measured variable values of the set of N variables is collected using by a training sensor set. The training data set includes empirical best match data values for the one or more operational parameters based on a comparison of a model image to images produced by a training imaging device.
