Scan takes too long

Chapter 9

•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.

•Check the original

◦Make sure that you loaded the original correctly. For more information, see Load 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.
