8-19Chapter 8 ISIS/TWAIN Driver Settings[Staple Detection] Check BoxSelect this check box to stop feeding when the sensordetects a folded corner on a document, which occurs whenan attempt is made to feed stapled documents. (See “StapleDetection” on p. 4-6.)[JPEG Transfer] Check BoxWhen this check box is selected, scanned image data isalways compressed to JPEG format within the scanner foroutput to the computer.Hint• Scanned image data is output from the scanner as anuncompressed or JPEG transfer, depending on instructionsfrom the ISIS/TWAIN driver or application program.– With uncompressed transfer, scanned image data is outputwithout being compressed. Therefore, if the image data islarge, transfer of the data from the scanner to the computermay take a long time.– JPEG transfer is useful for color and grayscale images, asscanned image data is JPEG-compressed within thescanner before it is output.This reduces the size of the image data for output, sotransfer time from the scanner to the computer is shortened.• When JPEG Transfer is selected, image data from thescanner is always output as JPEG-compressed data.– When the uncompressed saving format is selected in theapplication program, JPEG-compressed image data isreconverted to uncompressed data before it is transferred tothe application. Image quality deteriorates as a result.– This check box setting is ignored if the application programrequests a JPEG transfer.– Application program requests depend on the specificationsof the particular program.Image Compression RatioAdjusts the compression ratio of the scanned image data.Moving the slider towards [High Quality] reduces thecompression ratio and increases the image quality. Movingtowards [High Compression] increases the compressionratio. Although this reduces the file size, the image qualityis also reduced.Double Feed DetectionThis function stops document transport when doublefeeding of document pages is detected, and enables you toselect the detection method to suit the type of documentsto be scanned. (See “Double-Feed Detection” on p. 4-5.)[Detect by Length]This method of double feed detection is useful for batchscanning of same-size documents. The length of the firstdocument page fed is measured as a standard, and if asubsequent document is detected to be 1.38" (35 mm)longer (or shorter) than the standard, a double feed isjudged to have occurred, and document transport isstopped.[Detect by Ultrasonic]This method of double feed detection is useful for batchscanning of different-size documents. When the ultrasonicsensor detects overlapping documents and spacingbetween documents, a double feed is judged to haveoccurred, and document transport is stopped.HintBoth detection methods can be used together.[Setting] ButtonThis button is enabled when [Detect by Ultrasonic] isselected, and displays the [Detect Double Feed Setting]dialog box.In the [Detect Double Feed Setting] dialog box, you canselect the sensor position for detection and set a non-detection area so that the area where a stamp or label isaffixed to the document page is not detected as a doublefeed.
