David Kriesel found that copies 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 several Xerox models.
The company has not yet issued a fix for the problem, but it told the BBC it was preparing a statement. Mr Kriesel said he worried that numbers could be altered on invoices and other important documents.
He questioned whether incorrect figures could leave a company liable to legal action. Niri Shan, a partner at London-based law firm Taylor Wessing, told the BBC it could raise interesting legal implications. "The person who provided the figures would be liable [for any issues]. Then the question would be, could they turn round to the photocopying company and say, 'Hold on a minute, this is your fault'? "Often in commercial contracts, the manufacturer may have limitations of liability on consequential loss."
In his tests, Mr Kriesel found that often the number "6" would be turned into an "8", and vice versa, with other numbers being affected too.
