Imaging Device and Method for Sensing Media Type

Abstract

An operational imaging device and method for sensing a media type in a predetermined media set using a predetermined set of media type determining equations solved using measured values for a set of N variables measured by an operational sensor set in the operational imaging device. The solution of the equation set determines a media type. After a media type is determined, one or more operational parameters of the imaging device is selected for processing of a sheet of the determined media type. The equation set is generated by a training system using a classifier training engine. A plurality of training data sets containing measured variable values for each media type is collected under various conditions by a training sensor set that measures the set of N variables. After generation, the media type determining equation set is stored in memory of the operational imaging device.

AI Technical Summary

Benefits of technology

The patent is about a method for identifying different types of media used in a printing device. The method involves measuring various factors that uniquely define each type of media, such as electrical properties, optical properties, and bending stiffness. These measurements are then used to create a set of mathematical formulas that can be used to identify different types of media during the printing process. This allows for faster and more accurate identification of media types, which can improve printing efficiency and quality.

Problems solved by technology

Incorrectly setting media type is a well-documented problem for users of imaging devices, such as electrophotographic printers.

Setting media properties correctly is difficult for three primary reasons.

Second, paper setting menus are sometimes difficult to locate and navigate.

Third, classification of equivalent media is inconsistent.

Additionally, media moisture content and environmental factors may invalidate correctly chosen settings.

There are consequences to improperly selected media type settings.

Common failures related to improper media type settings include poor print quality, poor fusing, hot or cold offset, paper jams, media damage, component wear, and wrapping of the fuser by the media.

This leads to user dissatisfaction.

Prior art control schemes are limited in scope and are based upon an incomplete characterization of the media.

Such prior art systems still rely upon user input and lack a holistic approach.

However, the number of intrinsic property measurements required to adequately control an imaging device, such as an electrophotographic printer, without user input is prohibitive as this approach is neither cost nor space efficient and requires a large number of sensors.

Prior art sensing schemes have been incomplete because they have failed to measure some number intrinsic properties of the media needed to more accurately determine the media type.
