Erasure Method
T ime 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.

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.
