The specific embodiment
The maintaining method of a kind of ink gun of the present invention can be applicable on the ink-jet printer.Ink-jet printer comprises a carrier (carriage), and ink-jet printer utilizes motor to drive carrier, moves around with predetermined direction.Be fixed with an ink gun on the carrier, have a plurality of spray orifices on the ink gun, can spray ink, if there is the part spray orifice to stop up, ink can't spray smoothly, then needs spray orifice is carried out cleaning.Traditional maintaining method is to drive all spray orifice ejection inks, make the spray orifice of obstruction unimpeded, but unplugged spray orifice also sprays ink, can cause the serious waste of ink.Therefore maintaining method of the present invention is earlier spray orifice to be divided into groups, and so can judge it is which group spray orifice goes wrong by print result, only cleans that group spray orifice then to reduce ink dissipation.
Please refer to Fig. 3, it illustrates the schematic diagram according to the spray orifice grouping of a kind of ink gun of a preferred embodiment of the present invention.In this preferred embodiment, supposing has 10 spray orifices 302 on the ink gun 300, when spray orifice is divided into groups, two spray orifices 302 side by side can be defined as a spray orifice group, so can limit spray orifice group 310,320,330,340, five groups of spray orifice groups such as 350 grades.
Please refer to Fig. 4, it illustrates a kind of resolution chart corresponding with the spray orifice group of Fig. 3.In Fig. 4, butterfly-like resolution chart 400 can be made up of five p-wires, and these five p-wires have corresponding relation with the spray orifice group of Fig. 3 respectively.For example p-wire 410 is formed by the ink of spray orifice group 310 ejections, and in like manner, p-wire 420 is corresponding with spray orifice group 320, and p-wire 430 is corresponding with spray orifice group 330, and p-wire 440 is corresponding with spray orifice group 340, and p-wire 450 is corresponding with spray orifice group 350.
Then, drive the spray orifice group on the ink gun, make the print result of its ejection resolution chart 400, print the contrast of result and resolution chart then, control methods can be perusal, or uses the sensor sensing, to learn whether print result is complete, can learn is which group spray orifice group is stopped up; After selecting out the spray orifice group that needs cleaning, can carry out a cleaning at the spray orifice group of needs cleaning, for example the spray orifice group to the needs cleaning heats, or makes the spray orifice group ejection ink that needs cleaning, or the wiping spray orifice group that need clean, so that the spray orifice that stops up is unimpeded.
Certainly, resolution chart does not exceed with above-mentioned butterfly-like figure, please refer to Fig. 5, and it illustrates the another kind of resolution chart corresponding with the spray orifice group of Fig. 3.The resolution chart of Fig. 5 has comprised p-wire and numeral, the numeral that is positioned under the p-wire is to have represented through numbering and the spray orifice group corresponding with p-wire, for example the spray orifice group 310～350 on the ink gun is numbered the 1st group～the 5th group respectively, wherein the numeral 1 under p-wire 510 and the p-wire all is formed by the ink of the 1st group of spray orifice group (spray orifice group 310) ejection, in other words, Shuo Zi number clearly represents it is by the spray orifice group of which group ejection p-wire and numeral; In like manner, p-wire 520 and numeral 2 are corresponding with the 2nd group of spray orifice group (spray orifice group 320), and p-wire 530 and numeral 3 are corresponding with the 3rd group of spray orifice group (spray orifice group 330), and the rest may be inferred.
If the spray orifice group of ink cartridges is not blocked, resolution chart 400 or 500 print result will be identical with Fig. 4 or Fig. 5 respectively, and the line segment of each p-wire can both clearly present.If the part spray orifice of ink gun is blocked, then more or less all there are some seals not come out in each p-wire, make that the print result of resolution chart 400 or 500 is no longer complete, can in the spray orifice group, select out the spray orifice group of needs cleaning according to print result.And whether the resolution chart of Fig. 5 is complete as long as observe the p-wire of print result, contrast the numeral under it then, learn that immediately where organizing the spray orifice group stops up, and do not need the butterfly-like figure in the image pattern 4 to remove to contrast resolution chart, can omit the process of print result and resolution chart contrast, easier when selecting the spray orifice group that need clean.
In addition, because actual spray orifice number has hundreds of individual on the ink gun, spray orifice is very thin as if what divide when grouping limits, for example one group comprises 2 to maximum 10, and the spray orifice group that then limits is still a lot, has tens of groups of spray orifice groups, if a p-wire is corresponding with one group of spray orifice group, then resolution chart has just comprised tens of p-wires, and is on contrast print result and resolution chart, very not light.Therefore, the resolution chart of Fig. 5 can further be reduced to only needs ejection numeral 1～5, and omits p-wire, if which numeral is unclear in the print result, i.e. representative is which group spray orifice group needs cleaning.For example: numeral 3 seals are unclear, represent the 3rd group of spray orifice group obstruction, need cleaning, and therefore driving the 3rd group of spray orifice group makes it to spray ink, to eliminate clogging.This resolution chart of directly representing which group spray orifice group with numeral can be which spray orifice group is stopped up in interpretation to the user, and select out on the spray orifice group that needs cleaning, and is convenient and save time.
It should be noted that; method with the spray orifice classification; for example the included spray orifice number of one group of spray orifice group, do not exceed with above-mentioned group technology; and resolution chart does not exceed with two kinds of above-mentioned figures yet; as long as the p-wire in the resolution chart can be corresponding with the spray orifice group after the grouping, promptly in the technical scope of the present invention's protection.
Please refer to Fig. 6, it illustrates the maintaining method flow chart according to the ink gun of preferred embodiment of the present invention.At first in step 602, with all spray orifice groupings on the ink gun, limit a plurality of spray orifice groups earlier; When the user suspects the situation that the ink obstruction is arranged, can require printer to carry out one and print test (printtest), print off a resolution chart (step 604); Then, according to the p-wire of resolution chart, with range estimation mode or sensor, relatively print result and resolution chart can judge whether spray orifice blocked (step 606) is arranged; If judging has spray orifice blocked, promptly the spray orifice group of stopping up is carried out cleaning action, for example drive spray orifice ejection ink, or carry out spray orifice heating action, to eliminate the clogging (step 608) of spray orifice.After cleaning was finished, whether the spray orifice group of execution in step 604 and step 606 and judgement obstruction cleaned once more, if all unimpeded cleaning procedure that then can finish ink gun of spray orifice this moment, otherwise can repeat above-mentioned steps till spray orifice cleans fully.
In the above-described embodiments, though be to be example with the ink-jet printer, not as limit, the maintaining method of ink gun of the present invention also can be applicable on other image output devices, for example facsimile machine (Fax) and multifunctional paper feeding machine (Multi-Function Peripheral, MFP).
The advantage of apparatus of the present invention is, earlier all spray orifices on the ink gun are divided into some spray orifice groups, by the resolution chart corresponding with the spray orifice group, contrast with the print result of spray orifice group ejection ink, select out the spray orifice group that needs cleaning, and only clear up at the spray orifice of the spray orifice group of stopping up, the spray orifice group that does not have to stop up then must not spray ink, to avoid unnecessary consumption of ink, promptly reduce consumer's cost.
In sum; though disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, so protection scope of the present invention should be with being as the criterion that claim was defined.
