Erasing Data on Printer's Hard Disk

• 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.
