sane-umax1220u(5) SANE Scanner Access Now Easy sane-umax1220u(5)


sane-umax1220u - SANE backend for the UMAX Astra 1220U and similar scanners


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


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 (


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

See sane-usb(5) for information on how to set the access permissions on the usb device files.


/usr/lib/x86_64-linux-gnu/sane/ (present on systems that support dynamic loading)


If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity:

SANE_DEBUG_UMAX1220U values:

Number  Remark

1 print failures
2 print information
3 print high-level function calls
4 print high-level function checkpoints
9 print mid-level function calls
10 print mid-level function checkpoints
80 print protocol-level function entry
90 print protocol-level function exit

export SANE_DEBUG_UMAX1220U=10


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.

This backend isn't actively maintained. Nevertheless, bug reports and comments should be sent to the sane-devel mailing list. When reporting bugs, please run the backend with SANE_DEBUG_UMAX1220U set to 10 and attach a copy of the log messages.
