Drum Cleaning

Default:

Sets whether to rotate the drum in idle prior to

indicated by *). Select by scroll and Enter 
button.

hexadecimal Dump. Turning off the power 
supply switch restores Normal Mode.

Shutdown Start

Execute

Performs controlled shutdown of the printer, 
ensuring that all files on the internal hard disk are 
closed before power is turned off. Only power the 
printer off when the display indicates that 
shutdown is complete.
