Detection Functions
● Auto Image Type Detection
The scanner automatically detects whether documents
are in black and white or color.
● Auto Paper Size Detection
The document page size is detected before scanning.
Fixed-Size Scanning
● Skew Detection Function
The scanner stops feeding when a skewed document is
detected as it touches the edge of the feeder inlet.
"Skew Detection Function" on p. 4-6.)
● Staple Detection
The scanner stops feeding when it detects the presence
of stapled documents. (See "Staple Detection Function"
on p. 4-6.)
● Ultrasonic Double-Feed Detection Function
The scanner stops feeding when the ultrasonic sensor
detects that two or more document pages are feeding at
the same time. (See "Double-Feed Detection Function"
on p. 4-5.)
* A non-detection zone can be specified to avoid double-
feed detection in areas such as those containing adhesive
labels.
● Double-Feed Detection by Document Length
The scanner stops feeding when a double feed is
detected by comparing document lengths.
"Double-Feed Detection Function" on p. 4-5.)
* Using the length of the first document page as a reference,
the scanner detects a double feed when a page of a
different length is fed.

Chapter 1 Before You Start Using the Scanner
● Prescan
At the start of scanning, this function prescans the first
page of a document and pauses so that you can use the
first image to adjust the brightness and contrast before
resuming scanning.
● Verify Scan
While scanning, the count of document pages scanned
is verified against a pre-specified count or the count
obtained from Count-Only Mode.
on p. 4-4.)
● Text Orientation Detection
The text orientation on each page is detected, and the
scanned image is rotated in 90-degree increments as
necessary for normalization.
● Prevent Bleed Through/Remove Background
Prevents the background or original image on the
reverse side of thin originals from appearing in scanned
images.
● Image Rotation
The scanner can rotate scanned images in 90°
increments, or detect the text orientation and rotate the
image in 90° increments to correct its orientation.
● Deskew
The scanner straightens an image when it recognizes
from the image that the document page was fed askew.
