The machine administrator configures the Auto Erase Memory and Erase All Memory settings.
Before turning off the main power of the printer, always make sure that the Memory Erase Status has turned to “Currently no data to erase.”.
The printer will not enter Sleep mode until overwriting has been completed.
Should the Data Overwrite icon continue to be "Dirty" even after you have made sure that there is no data to be overwritten, turn off the main power of your printer. Turn it on again and see if the icon changes to "Clear". If it does not, contact your sales or service representative.
