Can I fax to more than 1 fax number at a time with the HP L7580?

I want to send a generic fax to all my clients informing them of my new mailing address. Do I have to send each fax individually or is there a way with my machine (HP L7580) to fax to more than 1 fax number at a time?

HP doesn't have info on operating the unit online. Look in the User's manual that came with the unit. If you don't have the manual, you can print it here:
