Keeping the Best Printing Results
z When unplugging the power cord
When unplugging the power cord, be sure to press [ON/OFF] first. When you press [ON/OFF],
the Print Head is protected by the cap to prevent the ink from drying. When unplugging the
power cord, be sure to unplug it after turning OFF the machine with [ON/OFF].
z When not using the machine for a long time
When not using the machine for a long time, print or copy in both black & white and in color, or
perform Print Head cleaning, about once a month to prevent degradation of the Print Head.
Numerous nozzles are installed in the Print Head for high-precision printing. Just as the
uncapped tip of a ballpoint pen or marker becomes dry and unusable if not used for a long period
of time, the Print Head nozzles become blocked by dried ink. Periodically printing or cleaning the
Print Head can prevent this blockage.
Note
Ensure that the Inner Cover is closed. Printing will not occur if the Inner Cover is open.
Caution
z Be sure to hold the Scanning Unit (Printer Cover) firmly using both hands, and be careful
not to get your fingers caught.
z Do not hold the LCD.
Note
z If <Some ink tanks are not installed in place.> is displayed on the LCD after the Scanning
Unit (Printer Cover) is closed, some ink tanks may be installed in the wrong positions.
Open the Scanning Unit (Printer Cover) and make sure that all the ink tanks are installed in
the correct order directed on the label.
z When you start printing after replacing the ink tank, the machine executes Print Head
cleaning automatically. Do not perform any other operations until the Print Head cleaning
finishes.
Note
If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat,
ink may blur depending on the paper.
