Solve scan problems
If the following topics do not help, see Support and warranty for information about HP support.
NOTE: If you are starting the scan from a computer, see the software Help for troubleshooting information.
•Part of the document did not scan or text is missing
•Scanned image quality is poor
Scanner did nothing
•Check the original
Make sure that the original is placed on the scanner glass 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.
•Check the software
Make sure the software is properly installed.
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.
