Erasing Data on Printer's Hard Disk
Important
• The administrator password is required to change settings if it is enabled for changing settings using the
operation panel.
• 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.
• You cannot erase HDD data if there is a job queue. Additionally, print jobs are not processed while data
erasing is in progress.

Fast
Erases file management data for print job data stored on the printer's hard disk. Choose this method
for relatively fast erasure. Because only the file management data is erased, the print job data itself
is not erased.
Fast secure
Erases the data encryption key specified for the hard disk drive. Specifying the encryption key again
does not allow you to read and use data saved in the past safely and fast. Select to erase highly
confidential data.
Secure
Overwrites the entire hard disk with 00, FF, and random data (one time each) after the data
encryption key specified for the hard disk drive is erased. Verification is performed to check if the
data was correctly written. Choose this method to erase especially confidential data. It is virtually
impossible to recover the overwritten data. Conforms to the DoD5220.22-M standard of the U.S.
Department of Defense.
Secure (VSITR)
Overwrites the entire hard disk with 00 next overwrites with FF after the data encryption key
specified for the hard disk drive is erased. After repeating this process three times, the entire hard
disk is overwritten with AA. It is virtually impossible to recover the overwritten data. Conforms to the
guidelines of German Federal Government (VS-ITR).
