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. 
[Erase Dot] Check Box
Select this to remove isolated black pixels (3×3 dots or smaller) from a white background, or isolated 
white pixels from a black background.
[Border Removal] Check Box
Select this to remove black borders surrounding scanned images.
[Punch Hole Removal] Check Box
Select this to remove the black spots from scanned images when scanning documents with punch 
holes. 
☞If punch holes are located within text or graphics in the document, they may be misidentified as 
graphics, and may not be removed.
[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.
 
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.

☞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. 7-7 for details.

[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.
[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.
[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 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 50 mm or more, a double feed is judged to have occurred and document transpor t is 
stopped.
☞Both detection methods can be used at the same time.
☞If the documents overlap by less than 50 mm, or if the documents cling (such as from static 
electricity,) ultrasonic detection of double feeds may be unreliable. 
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. 9-3.)
 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.
