Abstract
A method and apparatus for automatically adjusting nip width based on a scanned nip print in an image production device is disclosed. The method may include automatically inserting a sheet of media into a fuser nip in the image production device upon receiving a signal from a user interface, the fuser nip being an intersection of the fuser roll and the pressure roll, generating a nip print in the fuser nip, the nip print being an image created from the pressure between the fuser roll and the pressure roll, scanning the nip print, determining if a nip width adjustment is required based on the scanned nip print, the nip width being the distance of an arc length created by an intersection of the fuser roll and the pressure roll, and if it is determined that a nip width adjustment is required based on the scanned nip print, adjusting the nip width.
