When you put transparencies in the MP tray, please remember the following:
The side to be printed on must be face up.
Put the leading edge (top of the transparencies) in first and push it gently into the tray.
The top of the transparency stack must be under the maximum paper height guides that are on
both sides of the tray.

After you finish printing, close the back output tray.
Caution
Remove each transparency immediately after printing. Stacking the printed transparencies may
cause a paper jam or the transparency to curl.
