DEFECT DETECTION FOR PRINT MEDIA
An apparatus (20) for defect (D) detection in a printing system comprises an emitter (23) for emitting a signal towards a medium (S). A sensor assembly (25) is arranged for receiving at least part of the first emission signal reflected (R) from the medium. The apparatus is arranged for identifying a...

| description | An apparatus (20) for defect (D) detection in a printing system comprises an emitter (23) for emitting a signal towards a medium (S). A sensor assembly (25) is arranged for receiving at least part of the first emission signal reflected (R) from the medium. The apparatus is arranged for identifying a deformation in the medium from the received part of the first emission signal, and for determining a medium as suitable for printing when the first emission signal is substantially prevented from reaching the sensor assembly. A medium is determined to be suitable for printing when no signal reaches the sensor assembly. When the received signal exceeds a predefined reference, the apparatus determines a sheet to be unsuitable for printing. This configuration requires no strict alignment between the emitter and the sensor assembly, and is accurate despite vibrations and the like in the printing system. |
