Ok, a detailed response to this.

To find out how my Epson V700 is referred to on my computer, I did as
follows (where the command-prompt is indicated by $), and got he results
below:

$ sane-find-scanner | grep found
  # No SCSI scanners found. If you expected something different, make sure
that
found USB scanner (vendor=0x04b8 [EPSON], product=0x012c [EPSON Scanner]) at
libusb:002:009
found USB scanner (vendor=0x03f0 [HP], product=0xd102 [Photosmart B8500
series]) at libusb:002:008
  # found the scanner devices, be sure to adjust access permissions as

Thus, I followed your advice regarding the scanimage command, and got he
results shown below:

$ scanimage -d epkowa:usb:002:009 --help | grep resolution
    --resolution 25..12800dpi (in steps of 1) [300]
        Sets the resolution of the scanned image.
    --x-resolution 25..12800dpi (in steps of 1) [300]
        Sets the horizontal resolution of the scanned image.
    --y-resolution 25..12800dpi (in steps of 1) [300]
        Sets the vertical resolution of the scanned image.
    --short-resolution[=(yes|no)] [no]
        Display short resolution list

$ scanimage -d epson2:libusb:002:009 --help | grep resolution
    --resolution
50|60|72|75|80|90|100|120|133|144|150|160|175|180|200|216|240|266|300|320|350|360|400|480|600|720|800|900|1200|1600|1800|2400|3200dpi
[25]
        Sets the resolution of the scanned image.
    --short-resolution[=(yes|no)] [no]
        Display a shortened resolution list

It seems the epkowa backend supports more resolutions than he epson2
backend. So I guess I can just try epkowa in xsane.
