Scanning Results Are Not as Expected

If there is a problem with the scanning result (e.g., the scanned image is not clear, or the image is striped or dirty), the probable causes are incorrect ISIS/ TWAIN driver settings or a problem with the scanning unit inside the scanner. Scanning results can also become skewed if the ISIS/TWAIN driver has not been installed correctly, or the application in use does not support ISIS/ TWAIN driver functions.

Symptoms The scanned image is too dark (or faint).

Problem The [Brightness] setting is not set to an appropriate value.

Solution If the image is dark, set a higher [Brightness] setting, or if the image is faint, set a lower [Brightness] setting. (See “Brightness,” on p. 72.)

Symptoms Text or images on the rear side of your document appear in the scanned image.

Problem The [Brightness] setting is too low, or the paper is too thin.

Solution Set a higher [Brightness] setting. If the paper is too thin, make a copy of the documents and then scan the copy. (See “Brightness,” on p. 72.)

Symptoms Double-sided scanning is not possible.

Problem “Scanning Side” is set to [Simplex].

Solution Set “Scanning Side” to [Duplex].

Symptoms A black margin appears around the scanned document.

Problem A document smaller than the preset paper size has been scanned. Or, the loaded document has shifted out of position.

Solution Set [Page size] to [Auto-detection]. Or, set [Border Removal] to on. (See “Page Size,” on p. 68, and “[Border Removal] Check Box,” on p. 79.)

Symptoms The scanned image is skewed.

Problem The document has been fed at an angle. (skew)

Solution Use the document guide adapter to prevent document skew, and set [Deskew] to on. (See “[Deskew] Check Box,” on p. 70.)
