tell me about scanner setup options

• Use extended thickness paper handling

Scanning thick originals can give distorted results at both the top and bottom edges where the edge meets the scanner's rollers. You can omit edge distortion by letting the scanner skip the leading and trailing edges. Edge skipping is the default setting in one of the extended media positions. Use the checkbox Use extending thickness paper handling to enable and disable skipping of the two edges.

• Manual/Automatic

With manual loading, you position the original in the slot and then press the down button on the scanner.

With automatic loading, the scanner detects and loads the original as soon as you insert it.

...how do I define scanner setup options?

• Side/Center

You can load your original into the scanner from the scanner's center or side. Center loading is handy with standard sized originals (A4, A3, E-size, etc). Center loading is strongly recommended when scanning thick originals such as cardboard, foam-board, etc. Side loading is convenient when you want to use the ruler imprinted near the scanner's insertion slot to read the width.

• Delay factor

A delay factor can be set for automatic paper loading giving you time to position the original correctly.

This option allows you to fine-tune the scanner's vertical precision setting and mainly refers to copying where the relationship between lengths on the original must be kept in proportion. Examples are engineering drawings, maps and perhaps even some types of art posters.

During scanning, an original image is digitized as it is propelled through the scanner. One at a time, thin strips of the image are processed as they pass the cameras. Vertical precision is directly affected by the speed in which this happens. Inaccurate vertical precision makes vertical lines in the scanned image become longer or shorter than the same lines in the original. The vertical scan accuracy is adjusted and set mechanically during production of the scanner. This setting, is extremely precise and more than adequate for most purposes.

If you require very high accuracy, you can modify the vertical precision to a value between -1% and 1%. Positive settings mean that the distance between scan lines will be increased, and negative settings mean that the distance between scan lines will be decreased. When you exit the Scanner Setup dialog, the modified value is stored in non-volatile memory in the scanner and can only be changed by re-doing the setup.

The procedure for vertical precision adjustment would be to scan a precision original and measure the vertical distance between points in the image in a CAD or GIS system. Then compare those with similar physical measurements between the points on the original. You should scan at the scanning resolution you will later be using for the end result.
