Afternoon Huck, I spoke with the engineers this afternoon and was laughed at for asking such a fundamental question, its is a true 1:1 copy. Wether you purchase a .5copy or 85 copy a minute machine, well, for that matter my multifunction fax/scanner/printer at home defaults to 1:1 or 100%. I don't know what else to tell you.
Ag4ever, I can't empathize with your situation, I'm always going to construction sites (which by there very nature is a dirty environment) to clean machines. It sounds like your in need of a higher volume machine, say a 20k-40k copy a month type of machine, ha, ha!
