Chapter 8 Troubleshooting Image quality is poor when scanning pictures/ photos in black & white. Are you scanning in "Halftone" or "Grayscale"? Yes Are the glasses inside the ADF clean? Select [Halftone] or [Grayscale] in the scanner driver and scan. (*1) No Clean the inside of the ADF. For details, refer to "Chapter 6 Daily Care" (page 108). No Yes If the problem persists, check the items in "8.4 Before You Contact the Scanner Service Provider" (page 149) first, then contact your FUJITSU scanner dealer or an authorized FUJITSU scanner service provider. *1: The scanned image may differ from the original image significantly if you simply "binarize" (output in black & white) a picture or a photo. If the setting can be configured from the scanner driver's setup dialog box, set the image mode to [Halftone] or [Grayscale].
