Lexmark C790 manual Erasing printer hard disk memory, Using the Embedded Web Server

Erasing printer hard disk memory

Note: Not all printers have a hard disk installed.

Configuring Disk Wiping in the printer menus enables you to remove residual confidential material left by scan, print, copy, and fax jobs, by securely overwriting files that have been marked for deletion.

Using the Embedded Web Server

1From the Embedded Web Server, click Settings > Security > Disk Wiping.

Note: Printers without a hard disk will not display Disk Wiping in the Security menu.

2For Wiping Mode, select one of the following:

•Auto—Use this to automatically wipe data following each use (can increase the time between jobs).

•Manual—Use this to set up a schedule for disk wiping.

3Click Submit.

4From the Security menu, click Disk Wiping.

5If you have enabled Manual mode and wish to set up a schedule for disk wiping, click Scheduled Disk Wiping.

Notes:

•Scheduled Disk Wiping will not be displayed until after Manual mode has been selected and submitted.

•If you do not wish to schedule disk wiping, you can skip steps 5 and 6.

6Use the Time and Day(s) options to designate when disk wiping should occur, and then click Add. Repeat as needed to schedule additional times for disk wiping. When finished, use the browser Back button to return to the Disk Wiping setup screen.

Note: Disk wiping can take from several minutes to more than an hour, during which time the printer will be unavailable for other user tasks.

7From the Disk Wiping settings screen, select one of the following for each method of disk wiping (Automatic, Manual, and Scheduled):

•Single Pass— This lets you overwrite the printer hard disk in a single pass with a repeating bit pattern.

•Multi-pass—This lets you overwrite the printer hard disk with random bit patterns several times, followed by a verification pass. A secure overwrite is compliant with the DoD 5220.22-M standard for securely erasing data from a hard disk. Highly confidential information should be wiped using this method.
