Here it is.  I removed the part that does not depend on the device.
Note that the USB numbering may be different since I've been moving
the device between machines.

    Options specific to device `umax1220u:libusb:003:002':
	--resolution auto||75|150|300|600dpi [75]
	    Sets the resolution of the scanned image.
	--gray[=(yes|no)] [no]
	    Do a grayscale rather than color scan
	-l 0..228.6mm [0]
	    Top-left x position of scan area.
	-t 0..298.027mm [0]
	    Top-left y position of scan area.
	-x 0..228.6mm [0]
	    Width of scan-area.
	-y 0..298.027mm [0]
	    Height of scan-area.
	--lamp-off

    Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
