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.
