machine has a shutdown function. If the main power switch is turned off, the machine shuts down
safely by ensuring the following:

Corruption of files on the system hard drive, in the NAND flash memory, and on an SD card or
USB flash drive is prevented.

Loss of main power while paper (except jammed paper) is still in the machine is prevented.

All job and access logs are saved.
