When using the Yin Mo of above-mentioned physical property on common paper, to form image, can obtain no literal and leak the preferable image that profit is leaked on profit and look border.Especially, can realize the reproduction record of nature with the smoothness of Chinese character, oblique line portion and the curve part of complexity.And,,, can obtain stable print performance although be the also noseless obstruction of high viscosity even place 2～3.
Below, refer again to Figure 10 A-Figure 10 C and later figure, keeping in this image processing system recovered action describe.
At first, with reference to Figure 10 A-Figure 10 C, follow describing of the residual residual recording liquid of wiping to what the nozzle face 24a because of wiping record head 24 caused.Shown in this Figure 10 A, by making carriage 23 carry out motion scan under the state that rises in wiper blade 124 record head 24 is relatively moved, shown in this Figure 10 B, under the nozzle face 24a state of contact of this wiper blade 124 and record head 24, make wiper blade 124 move to the end of nozzle face 24a to the wiping direction, wiping is attached to the Yin Mo on the nozzle face 24a of record head 24.
Position before wiper blade 124 is about to leave from the wiping direction end of downstream side 24ae of nozzle face 24a stops to relatively move of wiper blade 124, shown in this Figure 10 C, wiper blade 124 is descended.Thus, can not deviate from (wiping) nozzle face 24a, can not disperse so be transferred to the Yin Mo of wiper blade 124 leading sections from nozzle face 24a because the leading section of wiper blade 124 keeps crooked state.
Yet, on the wiping direction end of downstream side 24ae of the nozzle face 24a of record head 24, produce the part that does not wipe, tend to adhere to the record liquid of no longer being handled (producing residual recording liquid DI) here.In the occasion of carrying out wiping repeatedly, this residual recording liquid DI is the growth that can not ignore degree, must shape because of adhering to that paper powder etc. is, thus can when image forms, clip the paper that adheres to drop and make the image disorder.
Secondly, with reference to Figure 11 A-Figure 11 C, the removal action of utilization being removed the residual recording liquid of the record head that parts 128 carry out describes.In addition, in Figure 11 A-Figure 11 C, diagram has been done simplification, the state that expression keeps 1 cover with 1 lid support.
Shown in Figure 11 A, carriage 23 and suction are stopped accordingly with lid 122a, record head 24 is stopped.By lid support 421A is risen to arrow D direction from this state, with lid 122a upwards move interlock, make and remove parts 128 rise (upwards action).
Like this by removing the upwards action of parts 128, shown in Figure 11 B, the leading section 128a that removes parts 128 contacts with residual recording liquid DI on the wiping direction end of downstream side 24ae of the nozzle face 24a that is attached to record head 24, as previously mentioned, because the wettability of removing parts 128 is bigger than the nozzle face 24a's of record head 24, removes parts 128 sides so the residual recording liquid DI of the nozzle face 24a of record head 24 is transferred to.
And because of removing the further rising of parts 128, shown in Figure 11 C, nearly all residual recording liquid DI is transferred to and removes on the parts 128, so can remove the residual recording liquid DI of the wiping direction end of downstream side 24ae of nozzle face 24a.
Like this, because have length direction setting along wiper member, the nozzle face of the record head after stopping to be carried out knee-action, and will be remained in the parts of removing that residual recording liquid on the wiping direction end of downstream side of nozzle face of record head removes relatively, so can fix, remove the residual recording liquid of removing the wiping rear end that remains in record head in the such action of parts rising at record head, can prevent because of paper powder etc. is attached to that residual recording liquid is must shape, and the situation that the image quality that makes image disorder etc. reduces, simultaneously, can also prevent the pollution of locking apparatus inside.
Secondly, with reference to the flow chart of Figure 12 and the mode declaration pattern specification figure of Figure 13 A-Figure 13 E, the example of recovering in the action of keeping in this image processing system is described.
Keep the recovery action according to this, at first, the record head 24 that recovers to move is positioned at and aspirates to use and cover the corresponding position of 122a, suction is risen with covering 122a, nozzle face 24a capping with record head 24, make cover and form negative pressure in the 122a by driving suction pump 423, aspirate the nozzle suction of seal China ink at nozzle 24n from record head 24 after, make suction with covering 122a decline (Figure 13 A).
Then, wiper blade 124 is risen, make carriage 23 carry out motion scan and wiper blade 124 is relatively moved, after the record head 24 nozzle face 24a after having carried out this nozzle suction are carried out wiping (wiped clean), make wiper blade 124 descend (Figure 13 B).
Then, once more by make suction with cover that 122a rises and with the nozzle face 24a butt of record head 24, the Yin Mo on the nozzle face 24a that will remain in record head 24 after the wiping is transferred to suction and uses and cover on the 122a.That is to say that the occasion at high viscosity seal China ink has sometimes and fails to wipe most situation by wiping fully, thus by make cover 122a and seal also residual after wiping black contact Yin Mo is transferred to cover 122a remove.
At this moment, also rise linkedly with covering 122a with suction owing to remove parts 128, so as previously mentioned, the Yin Mo of wiping direction end of downstream side that remains in the nozzle face 24a of record head 24 also removes on the parts 128 and removes (Figure 13 C) with regard to being transferred to.
Have again, carry out the 2nd wiping of nozzle face 24a of record head 24 making that wiper blade 124 rises, carriage 23 makes wiper blade 124 relatively move as motion scan after, make wiper blade 124 descend (Figure 13 D).
Then, carriage 23 (record head 24) is maintained fixed ground in this position, lid support 421A, 421B are risen and make and remove parts 128 and rise, carry out once more Yin Mo to the wiping direction end of downstream side of the nozzle face 24a that remains in record head 24 be transferred to remove parts 128 and remove scrape off action (Figure 13 E).
Then, for other record head 24, also can keep recovery to all record heads 24 by carrying out same action.
Like this, by 2 times wiping being utilized the removal action of removing the residual recording liquid that parts do respectively, can remove the residual recording liquid of following wiping and remaining in the nozzle face wiping direction end of downstream side of record head more reliably.
Here, describe to the structure of the transfer printing of removing parts 128 being used to improve residual recording liquid.
At first, be preferably, the nozzle face 24a (surface of the surface of nozzle plate 24N and nozzle casing 24b) of record head 24 applied refuse water treatment.In this occasion, lower by the water repellency that makes the surface of removing parts 128 than the water repellency of nozzle face 24a, just easily with the residual recording liquid of nozzle face 24a to the surface transfer of removing parts 128.
In addition, the formation of water-proof material film both can be the evaporation under vacuum, also can be to be dissolved in the coating of carrying out after the appropriate solvent.If with regard to the former, can be after for example being vented to the specified vacuum degree in vacuum tank with the vacuum jet pump, make the water repellency material gasify and import vacuum tank at 400 ℃, vacuum environment is regulated, and electric power is supplied with and produced RF glow discharge to sparking electrode from high frequency electric source, nozzle face to described liquid-discharging recording head under the plasma gas environment is carried out surface treatment, can form the described moisture film of refusing on nozzle face.In addition, according to the vacuum in material and the vacuum tank, also can refuse moisture film in formation under the low temperature of normal temperature to 200 ℃ degree.
With regard to the latter, can make the water repellency material dissolves in organic solvent, apply with anchor clamps such as steel wire roller and scrapers, also can use the rotation applicator roll to be rotated coating, or use spraying process to be coated with, or in soaking the container of full coating fluid, make dip coated.
As the water repellency material, can use organic compound with fluorine atom, particularly, use organic matter, have the organo-silicon compound of dimethyl disilane skeleton etc. with fluoroalkyl.
Organic compound as having fluorine atom is preferably, and uses fluoroalkyl silane, has the alkane, carboxylic acid, alcohol, amine of fluoroalkyl etc.Particularly,, 17 fluoro-1,1,2 can have been enumerated, 2-tetrahydrochysene decyl-trimethylsilicane alkane, 17 fluoro-1,1,2,2-tetrahydrochysene decyltrichlorosilane as fluoroalkyl silane; As alkane, octafluorocyclobutane, perfluoromethylcyclohexane (PFMCH), perfluoro-n-hexane, perfluor eicosane, ten tetrafluoros-2-methylpentane, perfluor dodecane can have been enumerated with fluoroalkyl; As carboxylic acid, perfluoro decane acid, PFO acid are arranged with fluoroalkyl; As alcohol, have 3,3,4,4,5,5,5-seven fluoro-2-amylalcohols with fluoroalkyl; As amine, 17 fluoro-1,1,2 are arranged, 2-tetrahydrochysene decyl amine etc. with fluoroalkyl.Organo-silicon compound as having dimethyl disilane skeleton have α, two (triamido propyl group) dimethyl silicone polymers of w-, α, two (glycidoxy) dimethyl silicone polymers of w-, α, two (vinyl) dimethyl silicone polymers of w-etc.
Again, the water repellency alcohol material as other can use the organic compound with silicon atom, the organic compound with alkylsiloxane base etc.
As organic compound with alkyl oxygen siloxy group, as contain in the molecule that contains the alkylsiloxane composition epoxy resin in formation the alkylsiloxane base, and the annular aliphatic epoxy radicals contain alkylsiloxane epoxy resin more than 2, can enumerate and contain the following general formula (a) and (b) macromolecular compound (A) of the formation unit of expression.
