Immediate Image Overwrite Algorithm
The overwrite algorithm for both IIO and ODIO conforms to the U.S. Department of
Defense Directive 5200.28-M (Section 7, Part 2, paragraph 7-202), and is common to
all WorkCentre/WorkCentre Pros and Accxes controllers.
The algorithm for the Image Overwrite feature is:
• Pattern #1 is written to the sectors containing temporary files (IIO) or to the entire
spooling area of the disk (ODIO). (hex value 0x35 (ASCII “5”)).
• Pattern #2 is written to the sectors containing temporary files (IIO) or to the entire
spooling area of the disk (ODIO). (hex value 0xCA (ASCII compliment of 5)).
• Pattern #3 is written to the sectors containing temporary files (IIO) or to the entire
spooling area of the disk (ODIO). (hex value 0x97 (ASCII “ú”)).
• 10% of the overwritten area is sampled to ensure Pattern #3 was properly written.
The 10% sampling is accomplished by sampling a random 10% of the overwritten
area.

Immediate Image Overwrite feature.
Set Thumbnail Creation
Thumbnails are miniature images of the scanned document that display on the Job
Information screen.
Thumbnails are the first page of a multipage job. They are used for job recognition.
Thumbnails only display if the feature has been enabled in the General Administration
screen and can be disabled when the System Administrator sets up a lockout password
to the feature.
This is a security feature that can be set to prevent exposure of confidential information
to any user.
The procedure to Set Thumbnail Creation is listed below:
1. Select Machine Info from the Services menu screen.
The Machine Information screen displays.
2. Select the Administration tab.
