- - Avoiding damage on flatbed scanners
-
- Most flatbed scanners have no protection against exceeding the physical scan
- area height. That is, if a scan is attempted with a height that exceeds the
- height of the scan surface, the scanner begins making loud noises and the
- scan mechanism may be damaged. Thus, if you hear such a noise, IMMEDIATELY
- turn off the scanner.
-
- Normally, the backend will ensure that the maximum scan height is not
- exceeded. However, if your scanner model has not been tested yet this
- safety-guard may not work. Please report errors like this to the author of
- the backend or the sane-devel mailing list.

- - Security problems with saned (SANE network scanning daemon)
-
- saned is not intended to be exposed to the internet or other non-trusted
- networks. Make sure that access is limited by tcpwrappers and/or a firewall
- setup. Don't depend only on saned's own authentification. Don't run saned
- as root if it's not necessary. And do not install saned as setuid root.
- Read man saned(8) for details.
