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.
Hint
 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. For 
details, see “Mode-Dependent Function Limitations” on 
p. 8-10.
Hint
[Batch Separation] and [Patchcode Orientation] are functions for 
setting the ISIS driver, so they are not displayed for the TWAIN 
driver. 
■[Others] Tab Sheet Settings
You can configure the following settings on the [Others] 
tab sheet. 
[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.

Chapter 8   ISIS/TWAIN Driver Settings
[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.
Hint
 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.
– With uncompressed transfer, scanned image data is output 
without being compressed. Therefore, if the image data is 
large, transfer of the data from the scanner to the computer 
may take a long time.
– JPEG transfer is useful for color and grayscale images, as 
scanned image data is JPEG-compressed within the 
scanner before it is 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 it is transferred to 
the application. Image quality deteriorates as a result.
– This check box setting is ignored if the application program 
requests a JPEG transfer.
– Application program requests depend on the specifications 
of the particular program.
[Staple Detection] Check Box
Select this check box to stop feeding when the sensor 
detects a folded corner on a document, which occurs when 
an attempt is made to feed stapled documents. (See “Staple 
Detection Function” on p. 4-6.)
Background Color
This rotates the scanner internal background roller to 
select the background color (black or white) of a 
document. (See “Selectable Background” on p. 4-7.)[White]
The background of documents changes to white and the 
black areas around scanned images are removed. 
IMPORTANT
When the background color is set to [White], [Border Removal] 
and [Punch Hole Removal] on the [Image processing] tab sheet 
are disabled. 
[Black]
The background of documents changes to black and the 
areas around scanned images become black. 
Hint
You can select [Border Removal] on the [Image processing] tab 
sheet to remove the black areas around images. 
Double Feed Detection
This function stops document transport when double 
feeding of document pages is detected, and enables you to 
select the detection method to suit the type of documents 
to be scanned. (See “Double-Feed Detection Function” on 
p. 4-5.)
[Detect by Length]
This method of double feed detection is useful for batch 
scanning of same-size documents. The length of the first 
document page fed is measured as a standard, and if a 
subsequent document is detected to be 1.97 (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 useful for batch 
scanning of different-size documents. When the ultrasonic 
sensors employed in three locations detect overlapping 
documents and spacing between documents, a double feed 
is judged to have occurred, and document transport is 
stopped. 
Hint
Both detection methods can be used together.  
						

							8-19
Chapter 8   ISIS/TWAIN Driver Settings
[Setting] Button
This button is enabled when [Detect by Ultrasonic] is 
selected, and displays the [Detect Double Feed Setting] 
dialog box. 
In the [Detect Double Feed Setting] dialog box, you can 
select the sensor position for detection and set a non-
detection area so that the area where a stamp or label is 
affixed to the document page is not detected as a double 
feed. 
IMPORTANT
 The area within 1.97 (50 mm) from a document edge cannot 
be set as the non-detection area. 
 If the documents overlap by less than 1.97 (50 mm), or if the 
documents cling (such as from static electricity), ultrasonic 
detection of double feeds may not word correctly.
Feeding Option
You can select the feeding method for document scanning.
[Standard Feeding]
Load a document and then start scanning with an 
application program. Scanning stops when the loaded 
document has been scanned. [Manual Feeding] (Bypass Mode)
This is linked to the [Bypass Mode] key on the control 
panel. When [Manual Feeding] is selected, the [Bypass 
Mode] key is lit and the document holder is raised up. 
Start scanning with an application program and feed 
documents manually one at a time. The scanner detects a 
document and then scans it. Press the stop button to stop 
scanning.
Hint
If you press the [Bypass Mode] key on the control panel, the 
feeding option changes to [Manual Feeding].
[Panel-Feeding]
Start scanning with an application program, load a 
document, and then press the start button to start the scan 
operation. 
The scanner enters a waiting state when the document has 
been scanned, and then continues scanning when you load 
the next document and press the start button. When all of 
the documents have been scanned, press the stop button to 
stop scanning.
Hint
When using the panel feeding mode to scan documents with 
different-size pages, you can adjust the document guide 
position after loading a document.
[Automatic Feeding]
Execute scanning with an application. The scanner starts 
scanning when it detects a document loaded in the 
Document Feed Tray.
The scanner enters a waiting state when the document has 
been scanned, and then continues scanning when it detects 
the next document. When all of the documents have been 
scanned, press the stop button to stop scanning.
