This feature erases all device settings stored in NVRAM, including network, security, and application settings, and all
pending jobs. Installed applications and settings are also removed.
If there is no hard disk installed, then pending fax data is also removed.
Disk file wiping
File-based disk wiping sanitizes the portion of the hard disk where data is stored after a job is processed, to remove
any residual data.
Some devices temporarily buffer scan, fax, print, and copy data that exceed the amount of RAM installed on the device.
Buffered data can be deleted from the hard disk immediately after the job is completed. Temporary data is also stored
on the hard disk when using the Confidential Print and Print and Hold features or sending and receiving held fax jobs.
This data remains on the hard disk until you print or delete the job, or until the document expires through the job
expiration feature.
When a data file is deleted from a hard disk, the data that is associated with that file is not actually deleted. This data
remains on the hard disk and can be recovered with substantial effort. All printer models with a hard disk support an
additional mechanism for protecting residual data, which is hard disk file wiping.
Hard disk file wiping actively overwrites any job data files that are deleted. You can overwrite data using a single or
multiple passes to remove all data residue from the deleted file.
All permanent data on the hard disk is preserved, such as downloaded fonts, macros, and held jobs. The multiple
‑
pass
wiping process adheres to NIST and DOD (DOD 5220.22-M) guidelines for overwriting confidential data.
The settings available for hard disk file wiping are Automatic, Scheduled, and Manual. Disk wiping for these three
methods can be either single or multiple pass. Single-pass and multiple-pass settings determine the number of overwrite
passes that are used during the wiping process. Highly confidential information should be wiped only with the
multiple
‑
pass method. Multiple-pass wiping takes longer than the single-pass version.
Note:
Automatic, Scheduled, and Manual wiping selections are available only if a formatted, working hard disk is
installed.
