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 the originals.

◦If you scanned the document from the ADF, try scanning the document directly from the scanner glass. For more information, see Load an original on the scanner glass.

◦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 Solution Center software, the default settings in the HP Solution Center 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 Solution Center 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

◦For OCR, the original must be loaded into the ADF with the top forward and face-up. Make sure that you loaded the original correctly. For more information, see Load the 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."

◦The accuracy of the OCR program depends on the image quality, text size, and structure of the original and the quality of the scan itself. Make sure that your original has good image quality.

◦Colored backgrounds can cause images in the foreground to blend too much. Try adjusting the settings before you scan the original, or try enhancing the image after you scan the original. If you are performing an OCR operation on an original, any colored text on the original does not scan well, if at all.
