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 printer
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.
