No Scanners detected error on Xerox PE16 AIO USB connection

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Nobody has an answer?

Please provide the output of the following diagnostic commands (with the device connected and switched on):

uname -a
lsb_release -crid
lsusb
sudo sane-find-scanner

According to http://ubuntuforums.org/showthread.php?t=980804 installing the driver for Samsung SCX-4216F might help.

As requested:

sudo sane-find-scanner
  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

By the way, the links provided are dead. I searched and found the Samsung web site but no Unix related drivers for the noted Samsung device. Thanks,

Try https://help.ubuntu.com/community/ScanningHowTo#Samsung_ALL-in-One_devices for the Samsung driver

Thanks but those instructions are for a LAN based scanner. As stated in my original problem description, this is a USB attached multifunction device.

Independent from the way that the scanner is connected, you need the correct driver for it.
