z Check the original
• Make sure that the original is loaded correctly. See Loading the originals for more
information.
z Check the all-in-one
• The all-in-one might be coming out of PowerSave mode after a period of inactivity,
which delays processing a short while. Wait until the all-in-one reaches the READY state.
• Make sure that the scanner is unlocked. Move the lock to the unlocked position, if
needed. See Printing supplies area for the location of the lock.

Scan takes too long
z 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.
• Color scanning takes longer than black-and-white scanning. 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.
z Check the status of the all-in-one
• 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.
