Tips on How to Use Your Printer 
This section introduces the tips on how to use your  printer and for printing with optimal quality.
 Ink is used for various purposes. 
 How is ink used for various purposes other than pr inting?
Ink may be used for purposes other than printing. I nk is not only used for printing, but also for
cleaning the Print Head to maintain the optimal pri nting quality.
The printer has the function to automatically clean the  ink jet nozzles to prevent clogging. In the
cleaning procedure, ink is pumped out from the nozz les. Used ink for nozzle cleaning is limited to a
small amount.
 Does black-and-white printing use color ink?
Black-and-white printing may use ink other than bla ck ink depending on the type of printing paper or
the settings of the printer driver. So, color ink i s consumed even when printing in black-and-white.
 Why does the printer have two black ink tanks?
There are two kinds of black ink in the printer: dye  ink (BK) and pigment ink (PGBK).
The dye ink is used mainly for printing photos, illustrati on, etc., and the pigment ink is used for text-
based documents. Each has different purposes so tha t even if one runs out, another will not be
used instead. If either of them runs out, the ink t ank replacement is required.
These two inks are automatically used depending on  the type of printing paper or the settings of the
printer driver. You cannot change the usage of thes e inks yourself.
 Ink lamp indicates when ink is running low.
The inside of the ink tank consists of (A) the part  where ink is preserved and (B) the sponge with
absorbed ink.
W hen the ink (A) runs out, the ink lamp flashes slowly  to indicate that the ink is running low. Then,
when the ink (B) runs out, the ink lamp flashes fast to indicate that the ink needs to be replaced with
a new one.
See Replacing an Ink Tank.

Place the printer at least 5.91 inches / 15 cm away  from other electrical appliances such as
fluorescent lamps. If the printer is placed closer  to those, it may not be able to work properly due t o
fluorescent noises.
 How to maintain the optimal printing quality? 
The key to printing with the optimal printing quali ty is to prevent the Print Head from drying or cloggi ng.
Always follow the following steps for optimal print ing quality.
 Follow the procedure below to disconnect the power  plug.
1. Press the 
ON button on the printer to turn it off.
2. Make sure that the  POWER lamp is not lit.
3. Disconnect the power plug from the wall outlet. 
If you press the 
ON button to turn off the power, the printer caps the P rint Head (nozzles)
automatically to prevent from drying. If you disconnect  the power plug from the wall outlet before
the  POWER
 lamp is turned off, the Print Head will not be cap ped properly and this will cause
drying or clogging. 
To disconnect the power plug, be sure to follow thi s procedure.
 Print periodically!
Just as the tip of a felt pen becomes dry and unusa ble if it has not been used for a long time,
even if it is capped, the Print Head too, may becom e dried or clogged if the printer has not been
used for a long time. 
W e recommend you to use the printer at least once a  month.
