Introduction
The e-shredding feature is a security feature which allows to overwrite any user print data and
any user print/copy/scan data when it is deleted from the system.
This feature prevents the recovery of any deleted user data (file's content and attributes).
A deleted job is a job that cannot be retrieved from any user interface.
When is a job deleted?
A job is deleted either:
• When it is manually deleted from a Smart Inbox
• After it was successfully printed and was not saved in a Smart Inbox
( 'Keep completed jobs in the Smart Inbox', 'Keep a copy of copy jobs in Smart Inbox', 'Keep a
copy of scanned jobs in Smart Inbox' and 'Keep a copy of local print jobs in the Smart Inbox'
system settings are disabled in the Océ Express WebTools)
• After a 'ScanToFile to external location' has been successfully performed
• After a 'ScanToFile to USB stick' has been performed successfully or not
• When it is automatically deleted after a time-out: the end of the job lifetime in the Smart Inbox
is reached
('Keep completed jobs in the Smart Inbox' is enabled, with 'Expiration time-out for Smart
Inbox' and 'Expiration time-out for Smart Inbox copy and scan jobs' set in the job management
settings of the Océ Express WebTools)
• When a 'Clear system' is performed on the printer user panel
• When a 'Clear system at next start-up' is selected in Express WebTools and the system is
restarted.
E-shredding algorithms
Select one of the three e-shredding behaviours:
• DOD 5220.22-M: 3-pass overwriting algorithm (compliant with the US Department of Defense
directive):
• Gutmann: 35-pass overwriting algorithm with random data
• Custom: set the number of passes, from 1 to 35.
NOTE
The e-shredding feature has been designed to minimise impact of the global system
performance.
However the more passes selected, the more impact it has on general performance.
It is recommended to minimise the number of passes when document production is required.
