a. When you use the JP-K31A, JP-K60, JP-F63, JP-K68, JP-K70, JP-T71,
JP-K77, JP-E78 or JP-K84 ink, you must complete the print head air-purge
procedure without regard to the humidity predominating in the employed
environment.
(See Section 1.2.6, "Print head air purge".)
b. (1) The JP-K31A, JP-K60, JP-K69 and JP-K84 inks employ carbon black as
the pigment.
If an excess electrostatic charge alarm is issued when no ink or makeup
ink is on the print head surface and ink drops are properly generated, it is
conceivable that carbon black may be deposited on the print head
surface.
This may have been incurred by creeping leakage on the deflection
electrode mounting surface. In such an instance, remove the deflection
electrode from the printer head and wipe the entire mounting surface
clean.
(2) The JP-K31A, JP-K60, JP-K69 and JP-K84 inks employ carbon black as
the pigment.
Shake the ink bottle well before use.
c. The carbon black pigment of the JP-K31A may cohere depending on the
employed environment. For enhanced pigment stability, you should perform
the following maintenance programs.
¡
Replace the main ink tank on a periodic basis (at intervals of about 2400
operating hours). When it needs replacement, contact your local
service personnel.
¡
Replace the stainless filter within the shutoff valve (MV9, mounted on the
print head) on a periodic basis (at intervals of about 2400 operating hours).
When it needs replacement, contact your local service personnel.
d. If the dye of the JP-K60 comes into contact with the human body, it cannot
easily be removed. Exercise utmost caution to avoid skin contact with it
.
e. The JP-K65, JP-R65 hardens if it is exposed to ultraviolet rays after printing.
Its hardenability varies with the printed matter material and surface condition
(roughness and presence of deposits), printed matter temperature, time
interval between printing completion and ultraviolet radiation, employed
ultraviolet radiation device, and other factors. You should confirm the ink
hardenability under the employed operating conditions.
Typical hardening conditions
Lamp type
Metal halide lamp (2kW)
Lamp light emission length 250mm (80W/cm)
Radiation distance 150mm
Radiation time 15seconds
If ink sticks to the end of the nozzle, the ink stream will be bent, the nozzle
may be clogged, or printing disorder may be caused. Before ejection, apply
the makeup ink to the orifice plate to wash it.
f. If JP-F63 has been deteriorated by light (corresponding to the irradiation of
sunlight for one month or more), light emission by ultra violet rays becomes
difficult. However, this condition can be improved into a light emission enable
status by applying a regenerating liquid (type: RF-B1, code No.: 451520).
g. The JP-B27 require to replace the stainless filter within the shutoff valve
(MV9, mounted on the print head) on a periodic basis (at intervals of about
2400 operating hours). When it needs replacement, contact your local
service personnel.
