(There is no blank exposure; see p. 4-5.)When the copy (cassette) size is a non-default size or when the copier is in the Reduce mode,the light from the pre-exposure lamp is directed to the photosensitive drum by way of the reflectingplate to prevent adhesion of toner; the blank exposure shutter is moved to open the exposure slitmaking use of the movement of the lens.Download Service Manual And Resetter Printer at http://printer1.blogspot.com
