Glossy color photo will not scan clearly Cause: Optical interference created by the photo adhering to document glass produces striped patterns Solution 1: Gently press down on the document cover Solution 2: Move the photo on the document glass to break the adhesion Solution 3: Clean the document glass (See p. 100) Stripes appear on scan of publication Cause: Moiré effect from scan of publication at low resolution (print screen lines highlighted by optical interference, producing striped patterns). This effect may occur with particular combinations of printed matter screen line densities and scanning resolutions Solution: Rescan at different resolutions or turn on the [Descreen] option (See the ScanGear CS-S or Plug-in Module CS-S Users Guide electronic manual). Whitened edges on image scanned from thick book Cause: Scanner employs an ultra-sensitive scanning unit that picks up ambient light entering around the edges of the book Solution: Cover the book and document glass with a dark cloth to prevent ambient light from affecting the scan Slow scanning speed Cause: Resolution is set higher than necessary Solution: Lower the resolution. 95
