7.1.4.4. Recommendations and corrective actions(1) If the CR plates are dusty, clean them according to the manufacturer’s protocol. Plates containing significantdefects should be replaced.(2) If it is found that plates must be cleaned frequently (more than weekly), this may indicate problems with dustin, or the cleanliness of, the imaging environment. If this is the case, attention should be given to ventilation(i.e. the possible need for improved air filtration or humidity control in the room and/or the CR plate reader)and room cleaning protocols.(3) If there are point-like dust artefacts (normally from dust on the screens) or lines (possibly caused by dust inthe CR light path), appropriate cleaning by the user, using the manufacturer’s recommended cleaningprocedure, should be performed. If this does not correct the artefacts, service support should be called.Note: Excessive frequency and/or aggressiveness of plate cleaning may lead to premature wear of the plates.See manufacturer’s instructions for cleaning and handling plates.46
