I want to know how i can use my copy machine to a fax so i can use it for incoming or outgoing?

Install software
Make sure all cables plugged: phone cable, USB cable to computer

Send fax from computer:
- print your document to printer HP .... FAX

Send "traditional" fax:
- put your document into scanner input
- type phone number on HP Officejet keyboard
- push button "Send"

If your HP Officejet if connected to phone line, it reseiving faxes automatically.

Hope this helps
