I've had this scanner for a couple of years using it seldom for normal documents. I have just started to scan my photo and slide collection and typically it seems to have developed a fault! There is a flare of light displayed on the glass when it is switched on and this appears in any photo placed over that area of the screen. For smaller pics I can place them elsewhere but this is a pain for bigger pics or multiple scans. I think it may be something to do with the fact that the scanner light is always on with the PC and has somehow permanently marked the glass on the inside. Has anyone else had a similar problem and can you suggest a solution please?
