ABSTRACT:
Method and apparatus for validating that a fuser member presumptively belongs to a class of fuser member for imparting a certain surface finish to an electrophotographic output print, and/or validating that the fuser member has a heating behavior within specification. Utilizing a temperature-sensing device for measuring temperature of the fuser member during heating thereof, a validation number is computed for comparison with a range of validation numbers associated with the class. If the validation number is included in the range, membership in the class is confirmed and/or the fuser member is shown to be within specification. Additionally, an auxiliary measuring device can be associated with the fuser roller to generate signals for computing, from measurements of a temperature-dependent property of the roller, a validation number relating to the temperature-dependent property.
