used paper roll
If the paper roll is not tightly rolled, roll it up more tightly
before reloading it.

When removing a partially used paper roll, be sure to place
the media tray on a stable surface before beginning.
If you drop the media tray while it contains a paper roll, it
could cause personal injury.
When removing and inserting the media tray, be sure
to use both hands, with one hand holding the handle
