Text cannot be edited

•Check the settings

◦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.

◦If you are using a separate OCR (optical character recognition) program, the OCR program might be linked to a word-processing program that does not perform OCR tasks. For more information, see the documentation provided with the OCR program.

◦Make sure you have selected an OCR language that corresponds to the language used for the document you are scanning. For more information, see the documentation provided with the OCR program.

•Check the originals

◦When scanning documents as editable text from the ADF, the original must be loaded into the ADF with the top forward and face up. When scanning from the scanner glass, the original must be loaded with the top facing the right edge of the scanner glass. Also, make sure the document is not skewed. For more information, see Load an original on the scanner glass or Load an original in the automatic document feeder (ADF).

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

◦The accuracy of the software 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.

Error messages appear

"Unable to activate TWAIN source" or "An error occurred while acquiring the image"

◦If you are acquiring an image from another device, such as a digital camera or another scanner, make sure that the other device is TWAIN-compliant. Devices that are not TWAIN-compliant do not work with the HP software.

◦Make sure that you have connected the USB cable to the correct port on the back of your computer.

◦Verify that the correct TWAIN source is selected. In the software, check the TWAIN source by selecting Select Scanner on the File menu.

Scanned image quality is poor

The original is a second-generation photo or picture

Reprinted photographs, such as those in newspapers or magazines, are printed by using tiny dots of ink that make an interpretation of the original photograph, which degrades the quality. Often, the ink dots form unwanted patterns that can be detected when the image
