scanned at 600 dpi, full color requires a minimum of 300 MB of disk space.

resolution.

approximately 10% to 20%.
Is the driver installed properly?
Remove the software (see "Uninstalling and Reinstalling the Software," on p.
1-23), then reinstall it. (See "Installing Software on Your Computer," on p. 1-4.)

with the MF Toolbox," on p. 3-7.)
