In order for you to use your printer as a fax you must have a phone line connected to the printer. Look on the back or printer and you should see a phone jack plug in. If you only have one phone jack in your house, you will need a wall jack splitter. This is for your land line phone and fax and they are only a few bucks most anywhere. If your pinter has it your set, the next step is to run your fax setup software that came with the printer. Since you have the printer software installed already,look in the solution center for something like [settings~fax settings and setup~fax setup wizard]. Then follow the on screen prompts and it will walk you right through it. Also, you should have received a manual with your printer, look in there...
