Assembling the Printer
When it is not in use, you can leave the tray attached to the printer
but rotated so that it rests on top of the printer. However, you
should lower the tray before you open the printer cover.
Note: The printer is factory set for face-down output on top of the
printer. If you prefer face-up delivery, simply move the paper
path selector (located on the left side of the printer) to the down
position.
