Abstract
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.
