(1) When you use the ink, you must complete the print head air-purge procedure without regard to the humidity
predominating in the employed environment. (See "3.1 Print head air purge" in the Technical Manual.)
(2) The ink employ carbon black as the pigment. (Shake the ink bottle well before use.)
If an excess electrostatic charge alarm is issued when no ink or makeup 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.
(See "6. [Instruction Manual] Supplementary items of "1. Usage precautions 1.3 Print head cleaning"".)
(3) If the ink has been deteriorated by light (corresponding to the irradiation of sunlight for ten hours or more), light
emission by ultra violet rays becomes difficult.
Light can be emitted if the ink is coated with regenerating liquid (Type: RF-P1, code No: 450260).
In environments exposed to direct sunlight, ink may deteriorate and emission intensity may drop.
When storing store in a cool place (0 to 20°C) inside a hermetically sealed container.
(4) Acetone is used as solvent for the ink. Acetone has characteristics of high vapor pressure (evaporable) compared
with MEK, so take care to with the following:
● Reference period for long-term shutdown will be shorter. Operate printer within the reference period
periodically, or perform maintenance work for long-term shutdown if shut-down time exceeds reference
period.
If the printer is shut down longer than reference time, re-start may not be possible due to settling of remaining
ink component. (See "5.(1) Estimated term of possible shutdown".)
(5) These ink uses ethanol as solvent.
The filter replacement* is required for stable operation.
The stainless filters are located in MV9 and Printhead.
For replacement, please contact your local distributor.
* Recommended time for replacement is every 12 months.
(6)When IJ printer is used for a long time, orifice plate surface gradually becomes dirty.
The position of ink stream may change due to stain of ink on the orifice plate surface. When the position
changing is critical, ink is accumulated inside of gutter. Then, print quality may degrade due to Ink overflowing
and leak current in cross-deflecting electrode. In this case, please clean the orifice and the gutter.
The method is below.
(a)Cleaning the orifice plate surface
Please wipe and clean orifice plate surface.
For the purpose of preventing the ink stream position change, clean print head before starting up the IJ printer
is recommended.
The step of cleaning the orifice plate surface is below.
Sprinkle the makeup on to the orifice plate.
Insert wipe paper between the Charging electrode and orifice plate and clean the orifice plate surface.
Finally, sprinkle the makeup on the orifice plate again and wipe off remain makeup.
(b)Cleaning the gutter
The step of cleaning accumulated ink inside of gutter is below
(Please see "1.8 Gutter cleaning" Instruction manual and "6.6 Cleaning the Gutter" Technical Manual)
Remove stain around the gutter by wipe paper with makeup.
Sprinkle makeup on to the gutter for 1 minute by running [Function: Cleaning the Gutter].
In the case of remaining ink stain inside of gutter, please run [Function: Cleaning the Gutter] again.
[NOTE] By running "Cleaning the Gutter" continuously, the concentration of ink becomes weak and
print quality may degrade. Do Not perform "Cleaning the Gutter" more than two successive
times.
