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, 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.
