cannot be taken care of by normal cleaning.
The menu that is open to the user offers 2 options, soft and normal.
Ink cartridge replacement
When an error occurs because ink has run out or an ink cartridge has not been installed,
the user should replace the ink cartridge, or if there is none, install one. In particular,
when ink has not yet passed through the head at all (when the plotter is shipped from the
factory), initial filling of ink is carried out so that ink will pass from the ink cartridge
through the tube to the head.
Miscellaneous
a) The cap inside the station must be kept at the proper humidity to prevent the nozzle
from drying out. For this reason, whenever the head is put into or taken out of the
station, ink is ejected to keep the nozzle moist. Conversely, if so much ink has been
ejected that the nozzle is too moist, ink is ejected from inside the cap to the waste ink
tank with the pump mechanism to keep the humidity at its optimum level.
b) This unit has a paper width sensor mechanism and a cutter mechanism in the head; the
paper width detection action and the paper cutting action make it necessary for the
head to move in and out of the station. The actions described in a) are necessary in this
case also.
