Patent ID: 8439351

Claim:
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 comprising: providing a stack-compressing element configured to contact a first piece of media in the stack of media, the first piece of media being more remote from a holding surface of the media holding receptacle than other pieces 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 after the second compressive force is applied to the stack of media, using the sensor to detect the position of the first piece of media.
