Chapter 8

Scan takes too long

•Check the settings

◦If you set the resolution too high, the scan job takes longer and results in larger files. To obtain good results when scanning or copying, do not use a resolution that is higher than needed. You can lower the resolution to scan more quickly.

◦If you acquire an image through TWAIN, you can change the settings so that the original scans in black and white. See the onscreen Help for the TWAIN program for information.

•Check the status of the device

If you sent a print or copy job before you tried to scan, the scan starts if the scanner is not busy. However, the printing and scanning processes share memory, which means that the scan might be slower.

Part of the document did not scan or text is missing

•Check the original

◦Make sure that you loaded the original correctly. For more information, see Load originals.

◦Colored backgrounds can cause images in the foreground to blend into the background. Try adjusting the settings before you scan the original, or try enhancing the image after you scan the original.

•Check the settings

◦Make sure that the input media size is large enough for the original that you are scanning.

◦If you are using the HP photo and imaging software, the default settings in the HP photo and imaging software might be set to automatically perform a specific task other than the one that you are attempting. See the onscreen Help for the HP photo and imaging software for instructions about changing the properties.

Text cannot be edited

•Check the settings

◦Make sure that the OCR software is set to edit text.

◦When you scan the original, make sure that you select a document type that creates editable text. If text is classified as a graphic, it is not converted to text.

◦Your OCR program might be linked to a word-processing program that does not perform OCR tasks. See the product software Help for more information about linking programs.

•Check the originals

◦Make sure that you placed the original correctly on the scanner glass. For more information, see Load originals.

◦The OCR program might not recognize text that is tightly spaced. For example, if the text that the OCR program converts has missing or combined characters, "rn" might appear as "m."
