Tray linking

Tray linking enables the automatic linking feature for trays when the same size and type of media is loaded in multiple
sources. The printer automatically links the trays; when one tray is empty, media feeds from the next linked tray.
For example, if the same size and type of media is loaded in tray 1 and tray 2, the printer selects media from tray 1 until it
becomes empty, and then the printer automatically feeds media from the next linked tray—tray 2.
By linking both trays, a single source with a capacity of 1100 sheets is created.
If the same size media in each tray is loaded, make sure the media is all the same type in order to link the trays.
Once the selected trays are loaded with the same size and type of media, select the same Paper Type setting in the Paper
Menu for these sources.
To disable tray linking, set the Paper Type to a unique value in each one of the trays. If all the trays do not have the same
type of media when they are linked, a job could mistakenly print on the wrong paper type.

Using the duplex function (two-sided printing)

Duplex printing (or two-sided printing) allows printing on both sides of a sheet of paper. Printing on both sides of paper
reduces printing costs.
