The original is too small. The minimum size that the flatbed scanner supports is 25
x 25 mm (1 x 1 inch).
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. See
Scanner resolution and color on page 61.
The scan takes too long The resolution or color level is set too
high.

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 device 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 device and scanner share memory,
the scan might be slower.
