Office equipment maker Xerox reported its fifth straight quarterly loss yesterday with a 13 per cent drop in revenues, citing a fall in sales of its copiers and printers in the aftermath of the September 11th attacks. The firm, with plants in Dundalk, Co Louth, and Dublin, reiterated it was "cautiously optimistic" it would deliver operational profitability in its current quarter. Xerox said its third-quarter net loss was $211 million (€237 million), or about 29 US cents a share, compared with a loss of $191 million, or 30 cents a share, a year ago.
