Check the settings

Make sure the HP software (or any additional OCR software) is properly installed.

When you scan the original, make sure that you select a document type or save the scan in a format that creates editable, searchable 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 an original on the scanner glass.

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.

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 device 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 is scanned or printed or when the image appears on a screen. If the following suggestions do not solve the problem, you might need to use a better-quality version of the original.

To eliminate the patterns, try reducing the size of the image after scanning.

Print the scanned image to see if the quality is better.

Make sure that the resolution and color settings are correct for the type of scan job.
