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 an original on the scanner glass.

◦If you are copying a borderless original, load the original on the scanner glass, not the ADF. 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 software, 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.

◦If you have selected a picture scanning option, the HP software automatically crops the image. However, if you want to scan the entire page, complete the following steps:

Windows: From the HP Solution Center software, click Scan Picture, click Advanced Picture Settings, and then select Scan the entire glass.

Mac OS X: From the HP Scan software, click Scan, select the Picturesscan profile, click Profile Settings, and then clear the Cropcheck box.
