Xerox scanners found to sometimes alter numbers |
August 06, 2013
Xerox scanners have been found to randomly alter numbers on documents when reproducing them if a certain combination of image quality and compression setting is used.
The problem first came to light last week when David Kriesel, a computer scientist pursuing a PhD at the University of Bonn, posted results of several scans on his website.
On Tuesday, Xerox acknowledged the problem and advised customers to use a higher quality scanner setting if it wanted to avoid the problem.
Kriesel said he first noticed the problem when he used a Xerox WorkCentre to scan to PDF some building construction documents. The documents were of a building floorplan and each room was marked with a small box that contained a room name and the area in square meters: 14.13m2, 21.11m2 and 17.42m2.
