ABSTRACT:
A method and apparatus for automatically adjusting nip width based on a scanned nip print image on ultraviolet (UV)-sensitive media in an image production device is disclosed. The method may include receiving a signal to generate a nip print, automatically inserting a sheet of UV-sensitive media into a fuser nip in the image production device, pausing the sheet of UV-sensitive media in the fuser nip for a predetermined time period, illuminating the UV-sensitive media with ultraviolet light to generate a nip print, scanning the generated nip print, determining if a nip width adjustment is required based on the scanned nip print, and if it is determined that a nip width adjustment is required based on the scanned nip print, adjusting the nip width using a nip width adjustment device.
