2-2. Ink system
2-2-1. Definitions
Ink system
Ink system is the general term of a mechanism specific to ink-jet printing system for
protecting a nozzle against troubles such as clogging and recovering it if it should be in
trouble.
Head capping
Head capping is a mechanism for automatically capping the nozzle so as to prevent it
from drying. As long as the head is on the station in the right-hand side cover, it is capped.
Clogged nozzle
In such an event that a specific nozzle fails to discharge any ink because the ink in the
head has thickened or the nozzle itself has dried up, the nozzle called the “clogged nozzle.”
Deflection
A finished state of a drawing on which lines are not plotted straight since a specific nozzle
has failed to discharge ink straight on the paper because of the dust-accumulated or damaged
nozzle surface.
Satellite
Discharged ink is shot as main drops or satellite drops.
If satellite drops are contained in main drops, the ink shot may shift.
Head cleaning
Recovers normal ink discharge by removing bubbles in the head and foreign objects on
the head surface.
Wiping
Wipes the nozzle surface with wiper rubber surface to fix the condition of nozzle holes in
order to remove foreign objects or ink leakage on the nozzle surface.
Flashing
Make idling discharges of ink which may thicken at the point of the nozzle, for refreshment.
Ink suction
Absorbs ink from nozzle by means of the ink suction pump.
Sleep refresh
If the front power switch is turned off when the main power switch is on, the sequence of
power-on R nozzle refresh R power-off is automatically repeated at fixed intervals to
prevent nozzle plugging.
