Abstract
A media stiffness sensor assembly for an imaging device. The assembly comprises a translation mechanism coupled to a contact member, a drive mechanism coupled to the translation mechanism and a position sensor for providing a signal indicative of the position of the contact member. The assembly is mounted within an imaging device so that the contact member is moved into bending contact with a cantilevered portion of a media sheet in the media path. The energy used to translate the contact member from a home position into the cantilevered portion of a media sheet in the media path to deflect the cantilevered portion is used to determine a weight of the media sheet.
