Erasing Data on the Printer’s Hard Disk

You can erase data on the printer’s hard disk from the Control Panel.

There are three ways to erase the data, as follows.

Erasure Method	Time Required	Details
High Speed	A few seconds	Erases le management data for print job data stored on the
		printer’s hard disk. Choose this method for relatively fast
		erasure. Because only the le management data is erased, the
		print job data itself is not erased. Note that it may be possible to
		read this data using commercial data recovery software.
Secure High Spd.	About 40 minutes	Overwrites the entire hard disk with random data. No verication
		is performed to check if the data was correctly written. Choose
		this method to erase highly condential data. Note that it may
		be possible to read the overwritten data using specialized data
		recovery tools.
Secure	About 30 hours	Overwrites the entire hard disk with 00, FF, and random data
		(one time each). Verication is performed to check if the data
		was correctly written. Choose this method to erase especially
		condential data. It is virtually impossible to recover the
		overwritten data. Conforms to the DoD5220.22-M standard of
		the U.S. Department of Defense.

Note

•For a more secure method of preventing data recovery, we recommend physically or magnetically destroying the hard disk. In this case, the hard disk can no longer be used.

•Erase HDD Data is not available if there is a job queue.

Also note that during execution of Erase HDD Data, print jobs cannot be processed.
