6 Advanced technical features

Experienced document management professionals might be interested in the following scan features. These features are available from any document TWAIN or ISIS application that allows you to modify the scan settings in its user interface.

•Long pages

•Color dropout

•Misfeed (Multipick) Detection

Long pages

By default, the automatic document feeder (ADF) accepts a stack of originals up to 215.9 mm x 355.6

mm(8.5 inches x 14 inches). You can choose to scan single pages up to 215.9 mm x 863.6 mm (8.5 inches x 34 inches) through the ADF.

NOTE: If the scanner is set to scan long pages and a page jams, up to 864 mm (34 inches) of document pages can be wrinkled as a result of the jam. Therefore, select scan profiles that specify long pages only when you are scanning pages longer than 355.6 mm (14 inches).

To enable long-page scans in an HP Smart Document Scan Software profile, follow these steps:

1.Open the HP Smart Document Scan Software.

2.Select a scan profile, and then click Edit.

3.Set the page size:

▲On the Scan tab of the Profile Settings dialog box, select Custom in the Size drop-down list, and then type the actual page dimensions, up to 215.9 mm x 863.6 mm (8.5 inches x 34 inches), in the Width and Height boxes.

TIP: Alternatively, you can select Maximum in the Size drop-down list. The resulting scanned image size will be 215.9 mm (8.5 inches) wide and the actual page length up to 863.6 mm (34 inches) long.

NOTE: Some scanning and destination applications might not support long pages.

Color dropout

You can filter out specific colors from a document scan, for example, you can remove colored lines on a form. Removing colors from the scan reduces the scan file size and can improve the accuracy of optical character recognition (OCR). You can select to filter out one color channel (red, green, or blue).

To eliminate a color from a scan in an HP Smart Document Scan Software profile, follow these steps:

1.Open the HP Smart Document Scan Software.

2.Select a scan profile, and then click Edit.

3.Configure color dropout:

a. On the Scan tab of the Profile Settings dialog box, click Advanced Settings.

b. On the Color Dropout tab of the Properties dialog box, select the channel to be dropped out.

Misfeed (Multipick) Detection

The Misfeed (Multipick) Detection feature stops the scan or copy process if it senses that multiple pages are fed into the scanner at one time. This feature is enabled by default.
