Abstract

A method of determining an amount of media in a stack of media that is disposed within a media holding receptacle of an imaging system, the method includes providing a stack-compressing element configured to contact a first piece of media in the stack of media; providing a sensor to detect a position of the first piece of media; applying a first compressive force to the stack of media via the stack-compressing element in contact with the first piece of media; applying a second compressive force to the stack of media via the stack-compressing element in contact with the first piece of media, the second compressive force being greater than the first compressive force; and using the sensor to detect the position of the first piece of media after the second compressive force is applied to the stack of media.
