❏ When using the printer, observe the operating
temperature and humidity range described in the
"Specifications Table". U
on page 163
Even when the conditions above are met, you may
not be able to print properly if the environmental
conditions are not suitable for the paper. Be sure to
use the printer in an environment where the paper's
requirements are met. For more details, see the
manual supplied with the paper.
Also, when operating in dry areas, air conditioned
environment, or under direct sunlight, maintain
the appropriate humidity.
❏ Capping may not occur (the print head is not
positioned on the right-hand side) if the printer is
turned off during a paper jam or when an error
occurs. Capping is a function for automatically
covering the print head with a cap (lid) to prevent
the print head from drying out. In this case, turn on
the power and wait a while until capping is
performed automatically.
❏ When the power is on, do not remove the power
plug or cut the power at the breaker. The print head
may not be capped properly. In this case, turn on the
power and wait a while until capping is performed
automatically.
❏ Do not move the print head by hand.

Notes when not using the printer

If you are not using it, note the following points when
storing the printer. If it is not stored correctly, you may
not be able to print properly the next time it is used.
❏ If you do not print for a long time, the print head
nozzles may become clogged. We recommend that
you print once a week to prevent the print head
from clogging.
❏ If the paper is left in the printer, the roller of the
paper presser may leave a mark on the surface of the
paper. This can also cause wavy or curled paper
resulting in paper feeding problems or the print
head could be scratched. Remove any paper when
storing.

❏ Store the printer after confirming that the print
head has been capped (the print head is positioned
at the far right). If the print head is left uncapped for
a long time, the print quality may decline.
Tip:
If the print head is not capped, turn the printer on, and
then turn it off.
❏ Close the roll paper cover and printer cover before
storing. If you are not using the printer for a long
time, put an anti-static cloth or cover on the printer
to prevent dust. The print head nozzles are very
small, and they can become clogged easily if fine
dust gets on the print head, and you may not be able
to print properly.
❏ If you have not used the printer for a long time,
check the print head for clogging before you start
printing. Perform head cleaning if the print head is
clogged.

Notes on handling ink cartridges

Note the following points when handling ink cartridges
to maintain good print quality.
❏ The included ink cartridges and installed
Maintenance Box 1 are just for initial ink charging.
You may need to replace the ink cartridge or
Maintenance Box 1 soon.
❏ We recommend storing ink cartridges at normal
room temperature, and to use them by the expiry
date printed on the cartridge packaging.
❏ For the best printing results, use up the ink cartridge
within six months of installation.
❏ If you move ink cartridges from a cold place to a
warm place, leave it at room temperature for more
than four hours before using the ink cartridge.
❏ Do not touch the green IC chip on the ink
cartridges. You may not be able to print properly.
❏ Install ink cartridges into all slots. You cannot print
if any slot is empty.
