Abstract
In printers using specially coated receiver, it is important that the coated receiver is loaded in the image-recording apparatus with the coated surface facing in the proper direction. Image stabilizers are used to extend the life of the image and are used to absorb ultraviolet light (UV) from sunlight and prevent the UV light from breaking down and decomposing the thermoplastic coating. Because these stabilizers are coated with the thermoplastic coating, the UV-absorbing materials therein can be used to detect the proper orientation of the recording sheet in the printer. Beams of light are directed against both surfaces of the recording sheet to detect the presence or absence of UV-absorbing material. In another embodiment, UV light fluoresces at a higher wavelength and this presence or absence of the higher wavelength is detected and from the measured light information reflected from each surface, the orientation of the recording sheet can be determined.
