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.
●
Skew Detection Function
The scanner stops feeding when a skewed document is detected as
it touches the edge of the feeder inlet.
●
Staple Detection
The scanner stops feeding when it detects the presence of stapled
documents.
(See “Staple Detection Function” on p. 74.)
●
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.
“Double-Feed Detection Function” on p. 72.)
* 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.
* 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.
●
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.
●
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.
Image Processing
●
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.
