Abstract
An apparatus in which sheet basis weight is determined as a function of a change in angular velocity of a roller defining a nip through which the sheet passes. The sheet basis weight is calculated in response to the change in angular velocity of the roll before and after the sheet enters the nip. In an electrophotographic printing machine, the change in angular velocity of the fuser roll or pressure roll may be used to calculate the sheet basis weight.
