[Reverse Image] Check Box (TWAIN driver only)
The document is scanned with black and white reversed when scanning in 
black and white (binary) mode.
[Edge Emphasis]
Adjusts image contours. Move the slider toward Soft to soften image contours, 
or toward Sharp to sharpen image contours.
[Document Orientation]
This setting selects an angle (0, 90, 180 or 270 degrees) to rotate scanned 
images for orientation normalization. 
☞Scanned images are rotated as follows according to the orientation of 
loaded documents and the selected rotation angle.
[Text Orientation Recognition] Check Box
Select this check box to detect text orientation in scanned images, and rotate 
images in 90º increments as needed to normalize orientation.
☞When [Text Orientation Recognition] is selected, [Image Rotation] and  
area settings in the Scan Area dialog box are disabled.
☞Some application programs do not support [Text Orientation Recognition]. 
Please disable [Text Orientation Recognition] if your application program 
behaves abnormally when it is enabled.

[Prevent Bleed Through / Remove Background] Check Box
Select this to Prevent Bleed Through when scanning thin document pages and 
those with dark content on the back side, or to remove the background from 
document images. 
When this check box is selected, the [Setting] button is enabled to allow 
adjustment of the removal level in the [Prevent Bleed Through / Remove 
Background Setting] dialog box.
 
[Reverse Image] Check Box (TWAIN driver only)
Select this check box to reverse (swap) black and white when scanning 
documents as black and white (binary) images.
Color Drop-Out
These selections are enabled for scanning modes other than 24-bit Color, so 
that you can select a primary color (red, green, blue) or gray to be ignored 
(dropped out) or enhanced.
The [Setting] buttons are enabled when [Drop-out color Custom] or [Custom 
Color Enhance] is selected, so that you can specify a color range in the [Color 
Settings] dialog box for drop-out or enhancement.  
						

							Software Setup81
Chapter 3
☞The color range within the shaded (cross-hatched) area is dropped out or 
enhanced.
☞You can move the shaded area by dragging with the mouse.
☞You can change the specified color range by dragging the edges of the 
shaded area. 
☞Because your operating environment affects the colors you specify on 
screen, they may not match those actually dropped out or enhanced: that is, 
the colors you specify may not match those processed.
[Others] Tab Sheet
The settings on the [Others] tab sheet are different for the ISIS and TWAIN 
drivers. Also, some settings may be disabled depending on the mode settings on 
the [Basic] tab sheet. Refer to “Mode-Dependent Function Limitations,” on p. 68 
for details.
ISIS driver TWAIN driver
[Reverse side]
Scanning occurs as follows depending on the scanning side settings.
☞When this check box is selected and the scanning side is set to [Simplex], 
only the back of each page is scanned.
☞When this check box is selected and the scanning side is set to [Duplex] or 
[Skip Blank Page],  the back of each page is scanned first, followed by the 
front.
[Rapid Recovery System] Check Box
If a paper jam causes paper transport to stop while scanning, scanning stops 
without sending an error notification to the application program. After fixing 
the cause of the stoppage, you can continue scanning with the standard 
operations. 
						

							82Software Setup
[JPEG Transfer] Check Box
When this check box is selected, scanned image data is always compressed to 
JPEG format within the scanner for output to the computer. 
Scanned image data is output from the scanner as an uncompressed or JPEG 
transfer, depending on instructions from the ISIS/TWAIN driver or application 
program.
☞Uncompressed transfers output raw scanned image data, so when the image 
data is large, significant time may be required for transfer from the scanner 
to the computer.
☞JPEG transfer is good for color and grayscale images, as scanned image 
data is JPEG-compressed within the scanner before output. 
This reduces the size of the image data for output, so transfer time from the 
scanner to the computer is shortened. 
When JPEG Transfer is selected, image data from the scanner is always output 
as JPEG-compressed data.
☞When the uncompressed saving format is selected in the application 
program, JPEG-compressed image data is reconverted to uncompressed 
data before transfer to the application. Image quality is degraded slightly as 
a result.
☞This check box setting is ignored if the application program requests a 
JPEG transfer. 
☞Of course application program requests depend on the specifications of the 
particular program.
Double Feed Detection
This function stops document transport when double feeding of document 
pages is detected, and provides selection of the detection method to suit the 
documents to be scanned. (See “Double Feed Detection Function,” on p. 52.)
[Detect by Length]
This method of double feed detection is good for batch scanning of same-size 
documents: the length of the first document page fed is taken as a standard, and 
when a subsequent document is detected to be 1.96 (50 mm) longer (or 
shorter) than the standard, a double feed is judged to have occurred, and 
document transport is stopped. 
[Detect by Ultrasonic]
This method of double feed detection is good for batch scanning of different-
size documents: the overlapping of documents transported in a batch is 
detected ultrasonically, and if the detected overlap is 1.96 (50 mm) or more, a 
double feed is judged to have occurred and document transport is stopped.
☞Both detection methods can be used at the same time.
☞If the documents overlap by less than 1.96 (50 mm), or if the documents 
cling (such as from static electricity,) ultrasonic detection of double feeds 
may be unreliable.  
						

							Software Setup83
Chapter 3
Feeding Option
Here you can select the feeding method for document scanning.
[Standard Feeding]
This feeding method is good for scanning small batches of documents that are 
loaded one batch at a time: scanning stops when the loaded documents have 
been scanned.
[Panel Feeding]
This feeding method is good for scanning batches of documents of different 
sizes: after loading the documents, press the Job button (assigned as a Start 
button on the scanner) to start scanning, and press the assigned Stop button to 
stop scanning.
☞When scanning documents with different-size pages, after loading the 
documents, you can adjust the document guide position.
[Automatic Feeding]
This feeding method is good for scanning batches of same-size documents: 
scanning starts when the scanner detects loaded documents, and stops when 
you press the Stop button.
☞When [Automatic Feeding] is selected, the [Setting] button is enabled to 
allow setting the delay time from when a loaded document is detected until 
scanning starts. (See “Scanning Multiple Documents,” on p. 94.)
☞When the feed selection lever on the scanner is in the down position ( ), 
the feeding option is set to bypass mode and cannot be changed. (See “How 
to Feed with the Bypass Mode,” on p. 30.)
 Batch Separation (ISIS driver only)
Items available for selection depend on the Feeding Option setting: select 
batch separation timing (for when to start scanning) according to the batch 
separation capabilities provided by the application program.

Each batch of documents is saved with different file names.
[Patchcode]
Batches are separated whenever a patchcode sheet is detected between 
documents. (See “Using Patchcode Sheets,” on p. 45.)
☞When [Patchcode] is selected, the [Folio] Scanning Side setting on the 
[Basic] tab sheet is not available.
Patchcode Orientation (ISIS driver only)
When [Patchcode] batch separation is enabled, you can select patchcode 
orientation here.
☞Settings for various patchcode types and orientations on document pages 
are as follows.
[Prescan] Check Box
When this check box is selected, the first document page is prescanned and 
displayed in the Prescan panel when scanning is first started. Continue 
scanning after you confirm or adjust brightness and contrast of the scanned 
image in the Prescan window. (See “Prescan,” on p. 99.)
[Barcodes] Button
This is enabled when the optional barcode module is installed: click it to open 
the Barcode dialog box and make settings affecting barcode detection in 
documents. For details, see the ISIS/TWAIN driver Help, or contact your 
supplier.
[Addon] Button
This button opens the [Addon] dialog box, where you can make setting for 
adding text or bitmap images to scanned document images.
