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 onscreen software Help for troubleshooting information.

Scanner did nothing

Check the original

Make sure that the original is loaded correctly. For more information, see Load originals.

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.
