That is, if a scan is attempted with a height that exceeds the 7141cc406Sopenharmony_ci height of the scan surface, the scanner begins making loud noises and the 8141cc406Sopenharmony_ci scan mechanism may be damaged. Thus, if you hear such a noise, IMMEDIATELY 9141cc406Sopenharmony_ci turn off the scanner. 10141cc406Sopenharmony_ci 11141cc406Sopenharmony_ci Normally, the backend will ensure that the maximum scan height is not 12141cc406Sopenharmony_ci exceeded. However, if your scanner model has not been tested yet this 13141cc406Sopenharmony_ci safety-guard may not work. Please report errors like this to the author of 14141cc406Sopenharmony_ci the backend or the sane-devel mailing list. 15141cc406Sopenharmony_ci 16141cc406Sopenharmony_ci- Security problems with saned (SANE network scanning daemon) 17141cc406Sopenharmony_ci 18141cc406Sopenharmony_ci saned is not intended to be exposed to the internet or other non-trusted 19141cc406Sopenharmony_ci networks.
