How Secure Erase works
When a job is deleted from the imagePRESS Server, the job cannot be viewed or retrieved using software provided
with the imagePRESS Server. However, if the job was spooled to the imagePRESS Server hard disk drive, elements of
the job may remain on the hard disk drive and can possibly be recovered with disk recovery tools.
Secure Erase clears job data securely from the hard disk drive by overwriting each job file three times. Secure Erase
applies only to deleted jobs.
We recommend leaving Secure Erase enabled at all times to ensure that data security is properly enforced.
Methods by which jobs can be deleted
Print jobs can be deleted in the following ways:
•
Users can delete jobs from the Hold queue.
•
Users can delete jobs from the Printed queue.
•
When the Printed queue limit is reached, older print jobs are automatically deleted from the Printed queue.
•
Print jobs sent to the Direct connection are automatically deleted (although the jobs may be retrievable from the
hard disk).
•
Scan jobs may be deleted automatically, depending upon the settings specified in Scan Setup.
•
Jobs are deleted if the server is cleared.
•
Print jobs that are sent using secure printing are automatically deleted after printing, or are deleted by the user
instead of being printed.
Job data not cleared by Secure Erase
The following types of print job data may persist even with Secure Erase enabled:
•
Jobs deleted before Secure Erase is turned on
•
Jobs for which deletion is incomplete when the imagePRESS Server is manually powered off (you can verify
deletion status in Command WorkStation)
•
Jobs merged into other jobs that are not deleted
•
Jobs stored on systems other than the imagePRESS Server, including:
•
Jobs sent to another imagePRESS Server (such as to balance the work loads)
•
Jobs archived to removable media or network drives
•
Jobs sent from client computers
•
Jobs sent through an FTP server
•
Jobs sent through an SMB connection
•
Portions of jobs written to the hard disk due to disk swapping and disk caching
•
Job Log entries, which are not deleted unless the administrator uses the Clear Server feature to delete the entire
Job Log
