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."
