FreeFlow Scanner 665 Hints and Tips# Feature/Function Hints/Tips1 Hole Fill Regular use of the “Hole Fill” function in the scanner requires daily cleaningof the paper guide on the automatic document handler (ADH). The paperguide is the long, dark gray, plastic strip on the underside of the ADH, has apattern of very thin images, and two cutouts for the rollers. The followingsteps should be used to clean this part:1. Apply “Xerox Lens and Mirror Cleaner (XPN 43P81)” to a clean, lintfree, non-abrasive cloth.2. Lift up the ADH.3. Identify the flat, dark gray paper guide on the right-hand, underside ofthe DADH. The paper guide is a long, flat piece of ribbed plastic, 5inches from the right-hand side of the DADH. The paper guide isapproximately 13 inches in length and 1 inch wide and pivots in theright/left motion when touched. This part also has two “cutouts” in it withtwo rollers resting in the cutouts.4. Rub the cloth in the right-to-left motion across the paper guide, startingat the back of the scanner, working your way to the front.CAUTIONBe careful not to dislodge the thin belt near the roller closest to the frontof the scanner.The system may inadvertently white-fill small “blocks” (~3-5 mm in size) ofa scanned image in areas of the original that are similar to the pattern onthe document feeder paper guide. To eliminate these white-fill blocks,disable the “Hole Fill” option.2 “Hole Fill” when“Reprocessing”images in “Preview”The “Reprocess” command does not eliminate holes.If a “Preview” of an image is made with “Hole Fill” turned off, and“Reprocess” is selected with “Hole Fill” off or on, the holes will not beremoved from the previewed image. Holes will be removed from the finalscan “Accept”.3 ScanningphotographsScanning photographs through the document handler is not recommendeddue to the potential for damaging the original, as well as the susceptibility of“streaks” in the resultant scanned image.4 Artifacts in“Automatic” modeWindows < 0.5” x 0.5” are categorized as “background” and subsequently,are processed differently from nearby windows (documents with a lot of“small sized” content, such as maps with “landmarks” on them, are mostsusceptible to this type of failure). This also occurs when scanning originalswith light shades of yellow and blue.NOTE: If this problem occurs, the document should be scanned in adifferent orientation, or off of the platen glass.
