	paper loaded in the paper tray, the machine can reduce the
	size of the document to fit the size of paper loaded in the
	machine. Select On if you want to automatically reduce an
	incoming page.
	With this feature set to Off, the machine cannot reduce the
	document to fit onto one page, the document is divided and
	printed in actual size on two or more pages.
Discard Size	When receiving a document as long as longer than the
	paper installed in your machine, you can set the machine to
	discard any excess at the bottom of the page. If the
	received page is outside the margin you set, it will print on
	two sheets of paper at the actual size.

	document to fit it onto the appropriate sized paper and

	discarded. Settings range from 0 to 30 mm.

	fax tones, enter the Receive Code. The Receive Code is
	preset to 9 at the factory. Settings range from 0 to 9.

	telephone line to answer several different telephone
	numbers. In this menu, you can set the machine to
	recognize the ring patterns to answer. For details about this
	feature, see page 6.13.
