Securely clearing job data
The Secure Erase feature provides a high level of document security by clearing job data from the E300 hard disk
drive after a job is deleted.
Each job data file is overwritten three times, which prevents recovery with disk recovery tools. The algorithm for
overwriting data is based on the DoD specification US DoD5220.22M.
How Secure Erase works
When a job is deleted from the E300, the job cannot be viewed or retrieved using software provided with the E300.
However, if the job was spooled to the E300 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.
Job deletion
A job can be deleted in the following ways:
•
A job is automatically deleted from the Printed queue after the queue is full.
•
A user deletes the job from the Hold queue.
•
A user deletes the job from the Printed queue.
•
A scan job is deleted based on Scan Setup.
•
A job is deleted when the user performs any of the Clear Server functions.
•
A user prints or deletes a Secure Print job.
Jobs not affected by Secure Erase
Secure Erase does not apply to the following types of jobs:
•
Jobs deleted before Secure Erase is turned on
•
Jobs located in systems other than the E300:
•
Copies of a job that are sent to another E300 (such as load balancing)
•
Copies of a job that are archived to media or network drives
•
Copies of a job that are located on user computers
•
Pages of a job that are merged or copied entirely into another job (for example, PDFs that are otherwise
merged)
