• When you start printing after replacing the FINE cartridge, the machine starts cleaning the print
head automatically. Do not perform any other operations until the machine completes the
cleaning of the print head.
• If the print head is out of alignment, as indicated by misaligned printed ruled lines or similar
symptoms,
• The machine may make noise during operation.
Notes on FINE cartridges
Important
• Do not touch the electrical contacts (A) or print head nozzle (B) on a FINE cartridge. The machine
may not print properly if you touch them.
• If you remove a FINE cartridge, replace it immediately. Do not leave the machine with the FINE
cartridge removed.
• Use a new FINE cartridge for replacement. Installing a used FINE cartridge may cause the nozzles to
clog.
Furthermore, with such a FINE cartridge, the machine will not be able to inform you when to replace
the FINE cartridge properly.
• Once a FINE cartridge has been installed, do not remove it from the machine and leave it out in the
open. This will cause the FINE cartridge to dry out, and the machine may not operate properly when it
is reinstalled. To maintain optimal printing quality, use a FINE cartridge within six months of first use.
Note
• If a FINE cartridge runs out of ink, you can print with either color or black FINE cartridge, in whichever
ink remains, only for a while. However the print quality may be reduced compared to when printing
with both cartridges. We recommend to use a new FINE cartridge in order to obtain optimum
qualities.
Even when printing with one ink only, print with leaving the empty FINE cartridge installed. If either of
the color FINE cartridge or black FINE cartridge is not installed, an error occurs and the machine
cannot print.
For information on how to configure this setting, see
• Color ink may be consumed even when printing a black-and-white document or when black-and-
white printing is specified.
Both color ink and black ink are also consumed in the standard cleaning and deep cleaning of the
print head, which may be necessary to maintain the performance of the machine. When ink runs out,
replace the FINE cartridge immediately with a new one.
