Important z Always press [ON/OFF] before disconnecting the power cord.

Before Printing
Turning The Machine ON/OFF
1
Press [ON/OFF] to turn the machine ON and OFF. Before turning ON the machine,
make sure the Document Cover is closed.
Important
Always press [ON/OFF] before disconnecting the power cord. This
ensures the FINE Cartridge is covered to prevent it from drying out.
If the machine is not used for an extended period of time, we
recommend making black & white and color prints/copies or
performing FINE Cartridge cleaning about once every month to
prevent degradation of the FINE Cartridge.(See page 90)
The FINE Cartridge has many nozzles in order to produce high-
definition prints. In the same way that the tip of a felt-tip or marker pen
will naturally dry out over time and become unusable even with the cap
in place, the nozzles might become clogged. Periodically printing or
performing FINE Cartridge cleaning can help to prevent this kind of
clogging.
Note
The power cannot be turned OFF with [ON/OFF] while the machine is
operating.
Your machine performs a FINE Cartridge cleaning every time you plug
in the machine. This ensures optimum print quality but also consumes
a small amount of ink during the cleaning process. We recommend
turning OFF the power with [ON/OFF].
The LCD goes out if the machine is not operated for 5 minutes. Press
any button to restore the display. You cannot change the period before
the LCD goes out.
