Problem Cause Solution
Part of the image did not scan. The original might have been loaded
incorrectly.
Load the original on the flatbed glass or use
the media guides when you load the
originals into the ADF. See
Load originals for
scanning on page 94.
A colored background might be causing
images in the foreground to blend into the
background.
Try adjusting the settings before you scan
the original or enhancing the image after you
scan the original.
The original is longer than 381 mm (15
inches).
The maximum scannable length is 381 mm
(15 inches) when you use the automatic
document feeder (ADF) input tray. If the
page exceeds the maximum length, the
scanner stops. (Copies can be longer.)
CAUTION: Do not try to pull the original
from the ADF; you might damage the
scanner or your original. See
Clear jams
from the ADF (photo card models only)
on page 196.
The original is too small. The minimum size that the flatbed scanner
supports is 25 x 25 mm (1 x 1 inch). The
minimum size that the ADF supports is 127
x 127 mm (5 x 5 inches). The original might
be jammed. See
Clear jams from the ADF
(photo card models only) on page 196.
The media size is incorrect. In Scan settings, make sure that the input
media size is large enough for the document
that you are scanning. .
The scan takes too long The resolution is set too high. Change the resolution settings to the correct
settings for your job. See
Scanner resolution
and color on page 100.
The software is set to scan in color. The system default is color, which takes
longer to scan even when scanning a
monochrome original. If you acquire an
image through TWAIN or WIA, you can
change the settings so that the original
scans in grayscale or black-and-white. See
the product software Help for details.
A print job or copy job was sent before you
tried to scan.
If someone sent a print job or copy job before
you tried to scan, the scan will start if the
scanner is not busy. However, because the
product and scanner share memory, the
scan might be slower.
The scanning PC may not have enough
available resources.
Close unused applications on the PC. If the
scan is still too slow, try rebooting the
scanning PC.
Antivirus, antispyware, or firewall software
on the scanning PC may slow scanning.
Consult your antivirus, antispyware, or
firewall software documentation.
