Outstanding features

Here is a brief summary of the outstanding features of your new scanner.

Enhanced Scan

Scanning quality is enhanced by providing an optical resolution of 400 dpi and gray scale scanning capa-

bility.

High-speed document feeding

The Automatic Document Feeder (ADF) delivers high-speed scanning on standard paper sizes up to A3

(297 × 420 mm) up to 53 sheets per minute (scanning A4 size, single-sided documents). Scanning docu-

ments placed on the flatbed is also extremely fast.

Flatbed scanning

The flatbed allows you to scan bound documents and originals that are too thin or fragile to feed from the

ADF.

Variety of scanning modes

The following modes can be selected for scanning jobs.

• Single-sided or double-sided documents

•Automatic feed of stacked documents or single manual feed

•Text (black and white) or photo (gray scale) mode scanning

Variety of image processing methods

The following processing methods can be applied to images as they are scanned:

• Dynamic Threshold

• Dither

• Image Emphasis

• Reverse Image

• Mirror Image

• Noise Reduction

• Automatic Separation

• Remove Shadow

Double-feed detection

Immediate detection of double-feeds pauses the scanning job and allows you to correct the problem with

having to remove jammed sheets from the scanner.

Skewed feed detection

This function detects skewed document feed and stops feeding to allow the problem to be corrected.
