Loading Letterhead
Place the printed side face up.
Linking Trays
Tray linking allows you to load the same size and type of print media in multiple sources. The printer automatically links the source/trays and uses the first tray
until it runs out, then switch to the linked tray.
If you load the same size print media in each tray, make sure the print media is the same type in order to link the trays.
When the selected trays are loaded with the same size and type of print media, select the Paper Size and Paper Type settings in the Tray Settings for each
source.
To disable tray linking, set the Paper Size and Paper Type to a unique value in each one of the trays. If all trays do not have the same type of print media
when linked, you could mistakenly print a job on the wrong paper type.
