About Invitation Letter

My invitee principal already have received my invitation letter & they sent me the scan copy, but for the national holiday of China, it was not sent to me till now. They can send it to me on 8th Oct, 2012 what we hope to receive around 10 or 11 Oct. Is it possible to apply for visa with scan copy as color/BW now & I can show the original when I can receive the VISA?
