Using the output support
The surface of the output tray may become hot if you print a large number
of pages at once. Make sure that you do not allow children near it.
Open the output support before printing. The printed pages stack on the output
support, and the output support will help the printed pages to align. The printer
sends printouts to the output tray by default.
