Scanner did nothing
• Check the original
Make sure that the original is loaded correctly. For more information, see
Load an
original on the scanner glass.
• Check the device
The device might be coming out of PowerSave mode after a period of inactivity,
which delays processing a short while. Wait until the device reaches the READY
state.
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 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 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.
