I-485 received in May 2006. Faxed FOIPA request to FBI but got returned. it says in letter：

The items listed below are exactly the form I got from the FBI web. I filled in all items to fax them. Does anybody know why it was returned? Do they accept fax? Do I have to mail the request to FBI?
Thank you in advance for any information.
