Erasing Data on Printer's Hard Disk

Only available with TM-355/TM-255/TM-5355/TM-5255.

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.
• Additionally, print jobs are not processed while data erasing is in progress.

1. Select (Setup) on HOME screen.

2. Select Printer settings.

3. Select Hard disk settings.

   If an administrator password is set, enter the password.

4. Select Data deletion.

5. Select erasing method.

   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).

6. Confirm the message and select Yes.

   Data on the hard disk are erased.
