Chapter 1 Before You Start Using the Scanner

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.

Scanning

●Skew Detection Function

The scanner stops feeding when a skewed document is detected as it touches the edge of the feeder inlet. (See “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. (See “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.

●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. (See “Verify Scan” 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.

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.
