Your machine prints received faxes on both sides of the paper when 2-sided is set to On.

You can set the machine to print the received date and time at the top centre of each received fax page.

If you are speaking on the telephone connected to your Fuji Xerox machine and the other party is also speaking on a telephone connected to his fax machine, at the end of the conversation, the other party can send you a fax before you both hang up.
