E-shredding presentation
Introduction
The e-shredding feature is a security feature which allows to overwrite any user print data (for
Océ ColorWave 600 / 650 PP) and any user print/copy/scan data (for Océ ColorWave 650 / 550)
when it is deleted from the system.
This feature prevents the recovery of any deleted user data (files' content and attributes)
A deleted job is a job that cannot be retrieved from any user interface.
The e-shredding functionality is available on:
- Océ ColorWave 600 R1.5 and higher
- Océ ColorWave 600 PP R1.6.1 and higher
- Océ ColorWave 650
- Océ ColorWave 650 Poster Printer
- Océ ColorWave 550
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' system setting is disabled in the Océ Express Webtools)
• After a 'ScanToFile to remote destination' has been successfully performed
• When it is automatically deleted after a timeout: 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' set in the job management settings of the Océ Express Webtools)
• When a 'Clear system Remove all jobs' is performed on the printer local interface
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.
