The sane-umax1220 library implements a SANE (Scanner Access Now Easy) backend for the the UMAX Astra 1220U and similar scanners.
For more information on this backend, please visit http://umax1220u-sane.sourceforge.net/.
This backend is also able to drive the UMAX Astra 1600U/2000U/2100U. The 2100U is confirmed to work. For the other scanners no reports have been received yet. Please contact us and tell us if your scanner works (firstname.lastname@example.org).
Usually, no manual configuration is necessary. The configuration file for this backend resides in /etc/sane.d/umax1220u.conf.
Its content is a list of device names that correspond to UMAX Astra scanners. Empty lines and lines starting with a hash mark (#) are ignored. A sample configuration file is shown below:
#usb vendor product usb 0x1606 0x0010 # Device list for non-linux systems /dev/scanner /dev/usb/scanner0
See sane-usb(5) for information on how to set the access permissions on the usb device files.

600 dpi scanning may fail for large image sizes.
If you keep getting I/O errors, try cycling the power on your scanner to reset it.
There is no way to cancel a scan, since the driver ignores sane_cancel().
If you try scanning an image which is too small, you will get I/O errors. Be sure to adjust the scan area before doing a scan, since by default, the scan area is zero.
