Oopsie.

Scans made by some Xerox copiers are changing numbers on documents, a German computer scientist has discovered.

David Kriesel found that scans he made of construction plans had altered room dimensions. Other users have replicated the problem, which has been blamed on faults with compression software used by the Xerox models.

The company has not yet issued a fix for the problem, but it told the BBC it was preparing a statement.

This is not an OCR problem (as we switched off OCR on purpose), it is a lot worse – patches of the pixel data are randomly replaced in a very subtle and dangerous way: The scanned images look correct at first glance, even though numbers may actually be incorrect.

Oh, boy. Let's think of documents with numbers in them that get scanned. Financial records...medical records....criminal records....

Why did you have to blow up the page to see the smiley, Elaine? Are you using a very small screen :scratch:?
