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.
Part of the document did not scan or text is missing
• Check the original
◦
Make sure that the original document meets minimum size requirements.
For more information, see Load an original in the scanner.
◦ Make sure that you loaded the original correctly. For more information, see
Load an original in the scanner.
◦ 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 software provided with the printer, the default
settings in the HP 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 software for instructions about changing the properties.
Text cannot be edited
• Check the settings
◦
When you scan the original, make sure that you select a document type in
the software 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, the original must be loaded into
the scanner with the top forward and face down. Also, make sure the
document is not skewed. For more information, see Load an original in the
scanner.
◦ 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."
