Reliable Paper Feed Mechanism
Scanning of Various Documents
Double-Feed Skip Function
Advanced Image Processing
The paper feed rollers rotate independently left and right to reduce
document skewing during scanning. In addition, the Active Double-
Feed Prevention Roller reverses rotation the instant that the leading
document leaves the paper feed section to prevent the double-feeding of
documents that are stuck together. These functions enable documents
with thicknesses from 20 to 209 g/m
2
(5.4 to 55 lbs.*)to be accurately
transported at high scanning speeds of 60 ppm.**
Document output control
The output speed is automatically lowered for
documents that are 148 mm or shorter, and the
exit guides keep the document from slipping.
This stops longer documents from sliding under
shorter ones to prevent the output order from
changing.
* Weight of 500 sheets (432 x 559 mm / 17 x 22 in.).

Compound paper scanning
A Double-Feed Prevention Roller
release mechanism is provided. By
lifting the manual feed selector,
compound paper such as carbonless
copy paper can also be fed.*
These scanners were designed to be
able to combine paper
documents along with a hard ID
card, such as a driver's license, in
a single batch by using the mixed
card batch guide. You can even scan
embossed cards smoothly.
Easy double-feed skipping
Double-feeding is detected by a highly reliable,
ultrasonic sensor to prevent feeding problems. When
scanning stops due to documents that include things
like envelopes or that have sticky notes attached,
simply press the Skip key to cancel the error and
resume scanning.
Improved scanning quality
The Automatic Brightness Adjustment function automatically adjusts the brightness
and contrast of scanned images, even on documents with varying paper colours and
text hues, to produce scanned images with suitable brightness. The Automatic Image
Emphasis function emphasizes the edges of characters and lines to sharpen them
and softens the appearance of other parts of the image. Noise (black spots) is also
reduced.

Missing image detection and prevention
When a scanned image is missing due to an inadvertently folded corner (dog-
ear) or a document that is extremely skewed, the Dog-Ear Detection function
automatically and temporarily stops the scanning. The user can then decide to
rescan, or to continue scanning as is.

be cancelled by a software setting. When scanning a document
manually, feed the document one set at a time.
