When moving the machine with the optional stand/paper drawer, be
sure to raise the adjusters. Also, unlock the two casters at the front of
the optional stand/paper drawer. After moving the machine, lower the
four adjusters until they reach the floor and lock the two casters.

5.Do not make any modifications to this machine. Doing so may result in

personal injury or damage to the machine.

6.Since this machine is heavy, it is recommended that it be moved by

more than one person to prevent injury.

7.When connecting this machine to a computer, be sure to first turn both

the computer and the machine off.
