Hard Disk Erasing Data on the Printer's Hard Disk When erasing all data on the hard disk, choose from the following three options. This operation is only available from the Control Panel. 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 Approximately 6 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. Additionally, print jobs are not processed during execution of Erase HDD Data. 1.
