(inspection operation)
Said inspection operation is said inspection liquid to be gushed out from said droplet discharging head check the operation of ejection characteristic.
Said inspection liquid can carry out through conventional method from the ejection of said droplet discharging head.For example, said inspection liquid is imported after the said droplet discharging head, remain in operation, can spray said inspection liquid from said droplet discharging head through making said ink-jet recording apparatus.
The inspection method of said ejection characteristic does not receive special qualification, can enumerate the inspection and the visual examination that for example utilize fluorescence.
At first, the ejection characteristic check that utilizes fluorescence is described.In utilizing the ejection characteristic check of fluorescence; As said zwitterionic dyestuff; Use is shone the dyestuff that sends fluorescence through ultraviolet ray, in this operation, will check that liquid is ejected to recording medium; And, utilize the fluorescence that produces by said irradiation to check said ejection characteristic to being sprayed with the said recording medium irradiation ultraviolet radiation of said inspection liquid.
The kind of said fluorescent dye and concentration such as said inspection liquid import the explanation of being carried out in the operation.
Then; In utilizing visual ejection characteristic check; For example, making said zwitterionic dyestuff is 0.1 weight %～0.25 weight % with respect to the concentration of complete inspection liquid, in this operation; To check that liquid is ejected to recording medium, check said ejection characteristic through the said recording medium that is sprayed with inspection liquid is carried out visualization.Through said visual examination, need not carry out the ultraviolet ray irradiation to said recording medium, can check said ejection characteristic simply.
The method that the recording medium that is sprayed with inspection liquid is carried out the method for visualization or utilizes the ultraviolet fluorescence that shines generation to observe more than has been described, but the inspection method of ejection characteristic also can adopt method in addition.For example, high speed camera capable of using is directly observed from the drop of the inspection liquid of droplet discharging head ejection.
Said inspection operation can comprise: to the ejection precision step whether satisfied first benchmark is judged of said used for water color ink shower nozzle and to ejection precision the step that whether satisfied second benchmark judge of said treatment fluid with shower nozzle.First benchmark and second benchmark do not receive special qualification, can enumerate for example for the determinating reference that sprays precision (for example, not having the crooked degree of ejection and ejection etc.) in the said ejection characteristic check.Said nothing ejection is meant the spray nozzle clogging of said droplet discharging head, thus the state that said inspection liquid can not be ejected.The crooked part of the nozzle of said droplet discharging head that is meant of said ejection is stopped up, and said inspection liquid phase can not vertically spray for said recording medium but be the state that tilts to spray.Generally speaking, the used for water color ink shower nozzle requires higher ejection precision than treatment fluid with shower nozzle.Therefore, the ejection precision of ejection ratio of precision second benchmark of preferred first benchmark is high.As first and second benchmark; For example can enumerate: said inspection liquid is filled to said droplet discharging head and is ejected under the situation of said recording medium; With the hit location of the inspection liquid on the recording medium all apart from standard hit location 15.0 μ m with interior scope in as first benchmark, will apart from standard hit location 30.0 μ m with interior scope in as second benchmark etc.The standard hit location is meant, from the infer desirable hit location of hitting of droplet discharging head with respect to the inspection liquid of the vertical ejection of said recording medium.
When the ejection precision of used for water color ink shower nozzle satisfies first benchmark, can be judged as this used for water color ink shower nozzle and be suitable as the use of used for water color ink shower nozzle.Likewise, when treatment fluid satisfies second benchmark with the ejection precision of shower nozzle, can be judged as this treatment fluid and be suitable as treatment fluid with shower nozzle and use with shower nozzle.On the contrary, when used for water color ink shower nozzle and said treatment fluid do not satisfy first and second benchmark respectively with shower nozzle, can be judged as these droplet discharging heads and be not suitable for respectively using with shower nozzle as used for water color ink shower nozzle and treatment fluid.
And then when two kinds of shower nozzles had mutually the same structure, useful was to carry out following judgement and processing.When the ejection precision of used for water color ink shower nozzle does not satisfy first benchmark, whether the ejection precision of this used for water color ink shower nozzle is satisfied second benchmark judge, when satisfying second benchmark, can this used for water color ink shower nozzle be judged as as treatment fluid and use with shower nozzle.As stated, treatment fluid with shower nozzle in most cases and do not require the height ejection precision as the used for water color ink shower nozzle.In addition, if used for water color ink shower nozzle of this embodiment and treatment fluid have mutually the same structure with shower nozzle, then can be used as any one droplet discharging head and use.Therefore, even do not satisfy under the situation of first benchmark,, then can be judged as and use with shower nozzle as treatment fluid if satisfy second benchmark in the ejection precision of used for water color ink shower nozzle.Like this, in this embodiment, be mutually the same structure through making used for water color ink shower nozzle and treatment fluid use shower nozzle, can reduce the quantity that possibly be judged as the used for water color ink shower nozzle that is not suitable for using and cancels, the result can realize the reduction of manufacturing cost.In addition; In this embodiment; Use contain with water color ink and treatment fluid in any one contacts the inspection liquid of the zwitterionic dyestuff that all is difficult to condense; Therefore, with purposes when the used for water color ink shower nozzle is changed into treatment fluid and is used shower nozzle, need not replace with numerous and diverse operation of other liquid such as pure water yet.
In the inspection method of the droplet discharging head of this embodiment, use contain with said water color ink and said treatment fluid in any one contacts the inspection liquid of the said zwitterionic dyestuff that all is difficult to condense.Therefore, used for water color ink shower nozzle and treatment fluid be with all can using this inspection liquid in the shower nozzle, and, can not need the said inspection liquid in these droplet discharging heads be replaced with other liquid such as pure water, and directly replace with said water color ink or said treatment fluid.Said alternative is as discharging through the said inspection liquid utilization suction in the droplet discharging head is removed, and the method that imports said water color ink or said treatment fluid is then implemented.In addition, suction is removed after the said inspection liquid, and the temporary transient preservation liquid that is used to preserve pipeline when going on the market that imports then, can replace with said water color ink or said treatment fluid with said preservation liquid according to user's operation.In this case, when importing said preservation liquid and when replacing with said water color ink or said treatment fluid, can not condense even do not carry out special processing yet.
