Слово "ксерокс" (а также производные от него слова) - используется как имя нарицательное не только в русском языке, хотя здесь не все гладко.

From Wikipedia: http://en.wikipedia.org/wiki/XEROX

"The word "xerox" (or "make a xeroxed copy", etc.) is commonly used as a synonym for "photocopy" (both as a noun and a verb) in North American English; for example, "I xeroxed the document and placed it on your desk." or "Please make a xeroxed copy of the articles and hand them a week before the exam". Though both are common, the company does not condone such uses of its trademark, and is particularly concerned about the ongoing use of Xerox as a verb as this places the trademark in danger of being declared a generic word by the courts. The company is engaged in an ongoing campaign to convince the public that Xerox should not be used as a verb.

To this end, the company has written to publications that have used Xerox as a verb, and has also purchased print advertisements declaring that "you cannot 'xerox' a document, but you can copy it on" a photocopier, particularly "a Xerox Brand copying machine." The AP Stylebook respects trademarks. Xerox Corporation continues to protect its trademark diligently in most if not all trademark categories. Despite their efforts, many dictionaries continue to mention the use of "xerox" as a verb, including the Oxford English Dictionary. However, in the United Kingdom, where the OED is based, the generic use of "xerox" as a term is uncommon. The terms "Photocopy" and "photocopier" are normally used instead"
