The specific embodiment
Describe fluid cartridge below with reference to accompanying drawings in detail according to the embodiment of the invention.
Fig. 1 shows the cutaway view according to the schematic structure of the fluid cartridge of the embodiment of the invention, Fig. 2 shows the flow chart of the black liquid ejection control method in the ink-jet printer that fluid cartridge shown in Figure 1 is installed, and Fig. 3 shows the curve map that concerns between black liquid ejection control method mid point count value shown in Figure 2 and the exhausted amount of ink.
As shown in Figure 1, according to the print cartridge (fluid cartridge) the 1st of this embodiment, the atmosphere communicate-type, it comprises the inking chamber (fluid chamber) 5 that is used to hold black liquid 4 in the container body 3 of the box mounting portion 2 that will be installed to ink-jet printer (equipment), the liquid supply port 7 that will be connected with black liquid receiving portion (liquid-receiver part) 2a of box mounting portion 2, be used to make inking chamber 5 to supply the fluid passage 9 that port 7 is communicated with liquid, be used for extraneous air being incorporated into the atmosphere open communication (not shown) of inking chamber 5 along with the consumption of inking chamber 5 China and Mexico's liquid 4, be arranged in the middle of the fluid passage 9 and be used for and be supplied to the pressure controlling of black liquid of black liquid receiving portion 2a to the pressure controlling device (negative pressure generation device) 11 of predetermined pressure by liquid supply port 7, and ink end point sensor (liquid sensor) 13, this sensor 13 is arranged on the upstream side of fluid passage 9 intermediate pressure regulation devices 11 and is used to detect the existence of inking chamber 5 China and Mexico's liquid 4.
For example, box mounting portion 2 is arranged in the carriage (not shown), and this carriage is installed and is used for black liquid is ejected into printhead (jet head liquid) on the paper (medium), and is configured to and can moves back and forth along the direction with the throughput direction quadrature of paper.
In this embodiment, ink end point sensor 13 is that black liquid exists or do not exist checkout gear, be used for producing vibration and detecting the existence of black liquid or do not exist based on residual oscillation by piezoelectric vibrator, described residual oscillation still is that air changes according to there being black liquid in the fluid passage 9.Black liquid in inking chamber 5 is entered under the situation of fluid passage 9 by full consumption and the air that is incorporated into the inking chamber 5 from the atmosphere open communication, and ink end point sensor 13 detects black liquid and do not exist, and the output indication does not have the signal of black liquid.
In situation according to the print cartridge 1 of this embodiment, cushion chamber 15 is arranged on the fluid passage 9 between ink end point sensor 13 and the pressure controlling device 11, buffer memory chamber 15 storage will be fed to the black liquid 4 of liquid supply port 7 by pressure controlling device 11, and can detect the black liquid of supplying constant basis after not having black liquid at ink end point sensor 13.
In addition, be set to be contained in roughly 10% of effective ink amount in the print cartridge 1 (effectively amount of liquid) according to this embodiment black liquid memory space (memory space of liquid storage) of (capacity that comprises the fluid passage 9 between ink end point sensor 13 and the pressure controlling device 11) in cushion chamber 15.In other words, the capacity of cushion chamber can comprise the capacity of the fluid passage between ink end point sensor 13 and the pressure controlling device 11.Effective amount of liquid of print cartridge 1 refers to be contained in the liquid storage amount in the inking chamber 5 and cushion chamber 15 at least.
More specifically, the effective ink amount in the black liquid in being contained in print cartridge 1 is 10 whens gram roughly, and the black liquid memory space in the cushion chamber 15 is for roughly 1 restraining.
And when roughly effective ink amount of 90% was consumed, the control circuit 19 of inkjet printing pusher side was judged low ink state and is taken place, and the residue of ink liquid measure is very little in this low ink state China and Mexico water cavity 5.
And, be provided with the memory circuitry 17 that is used to store about the information of the amount of residue of ink liquid 4 according to the print cartridge 1 of this embodiment.Memory circuitry 17 is connected to the splicing ear 18 on container body 3 outer surfaces.And ink end point sensor 13 also is connected to splicing ear 18.
When print cartridge 1 was installed to box mounting portion 2, splicing ear 18 was electrically connected to the splicing ear 2b of box mounting portion 2 sides, and ink end point sensor 13 and memory circuitry 17 are connected to the control circuit 19 of printer side by splicing ear 2b and 18.
Control circuit 19 is carried out the some counting that the amount of the drop of the black liquid 4 that goes out from the nozzle ejection of printhead is counted and calculated and is handled in the print processing of ink-jet printer, execution such as the maintenance with the corresponding cleaning of the mode of operation of ink-jet printer is handled, perhaps by the existence of the black liquid 4 from the signal detection inking chamber 5 of ink end point sensor 13 outputs and finally provide the instruction that stops to print and changing print cartridge 1 based on the drip point count value of the black liquid 4 that is counted and calculates.
In addition, control the processing of spraying black liquid 4 in the ink-jet printer corresponding to the residue of ink liquid measure in the print cartridge 1 according to the control circuit 19 of this embodiment.
More specifically, control circuit 19 is controlled the processing of spraying black liquid 4 by black liquid ejection control method shown in Figure 2.
At first, judge whether print cartridge 1 is installed to box mounting portion 2 (step S101).Be mounted if judge print cartridge 1, then begin the some counting of counting and calculating from the drop amount of the black liquid 4 of printhead ejection in the print processing is handled (step S102).
Then, carry out to judge that handling the point whether count value that obtains reach default print cartridge 1 effective ink amount by a counting counts judgment processing (step S103).
If reach 100% (with the ratio of effective ink amount), then handle and advance to the step S104 that stops using print cartridge 1 as the ink terminal point in step S103 judging point count value.
If less than 100%, then handle and advance to next step S111 in step S103 judging point count value.
At step S111,, judge whether to satisfy and be used to detect that black liquid exists or there is or does not exist testing conditions in non-existent ink based on signal from ink end point sensor 13 output.For example, being used to detect ink existence or non-existent condition is whether the timing that infeeds/discharge paper, time-out printing work or beginning cleaning produces.By judging whether to be in default timing, judge whether to satisfy as carrying out and detect the ink existence that requires or do not have testing conditions.
If judge that at step S111 satisfying ink exists or do not exist testing conditions, then handle advancing to next step S112, wherein detect the existence of black liquid or do not have (there is judgment processing in black liquid) by ink end point sensor 13.
If judge that at step S112 black liquid exists, then the point in past is counted (step S113) continuously and this processing turns back to step S103.
On the other hand, if judge that at step S112 ink does not exist, then handle advancing to step S121.
At step S121, when judging that also black liquid exists just now, low ink state then judge to take place and carry out the some counting and proofread and correct and handle, this point counting is proofreaied and correct to handle and will be judged also just now that some count value that black liquid is obtained when existing is corrected into default predetermined point count value (for example 90%) and also further will be added to the predetermined point count value of such correction to the some count value that the current time calculated from judging time that black liquid also exists just now.Then, processing turns back to step S103.
Except will carrying out the print processing of a counting, the maintenance such as cleaning is handled and is also consumed black liquid 4.In addition, the number of times of carrying out the maintenance processing such as cleaning uses the situation of printer to change according to the user.
Therefore,, select 100% some count value by this way, make that as shown in Figure 3 effective ink amount consumption of print cartridge 1 is 10 grams roughly as effective ink amount when some count value under the application feature of carrying out average cleaning therein when reaching 100%.
According to the print cartridge 1 of this embodiment, obviously detect when not having black liquid to stay when ink end point sensor 13, with in the print cartridge 1 effectively the roughly 10% corresponding black liquid 4 of ink amount remain in the cushion chamber 15 that is arranged in fluid passage 9 ink inside end point sensors 13 downstreams.
Therefore, but if with the roughly 10% corresponding allowed band of print cartridge 1 effective ink amount in carry out the print processing of ink-jet printer, detecting at ink end point sensor 13 does not then have black liquid to change print cartridge 1 after staying, then residual ink amount can be minimized in the print cartridge 1 that will unload by replacing, because the black liquid 4 in the cushion chamber 15 is almost by full consumption.
And when 13 detections of ink end point sensor did not have black liquid to stay, the ink amount that stays in cushion chamber 15 was clearly.Therefore, print processing subsequently can continue to carry out carefully for a long time.As a result, can prevent from reliably to spray the shortcoming that causes by the sky of inkjet printing pusher side, should the sky injection be that lasting use causes under the empty state owing to the residue of ink liquid measure in print cartridge 1 is consumed fully wherein.
And, according to black liquid ejection control method shown in Figure 2, handle count value and proofread and correct to handle by the some counting of step S121 and be corrected by the drop amount of black liquid 4 being counted and calculated the some counting that is obtained.
Therefore, in the situation of the fluctuation of the volume of the some counting process errors that same stored counts after existence is admitted port 2a by the black liquid that print cartridge 1 is installed to box mounting portion 2 causes, the fluctuation of printhead emitted dose or inking chamber 5 or the ink amount that is held, can improve the precision of count value, in the some counting judgment processing of step 103, this count value has been used to judge whether to reach effective ink amount of print cartridge 1.Therefore, can reduce the detection surplus of residual volume.
For example, if be used for the equalization point count value that an effective ink amount of counting judgment processing is set as the consumption of general application state, and in addition as mentioned above, black liquid memory space in the cushion chamber 15 of print cartridge 1 is set as roughly 10% of effective ink amount, then also can prevent empty generation of spraying during repeating to change the situation of (promptly in use unload print cartridge 1 from ink-jet printer or reinstall) midway.
Fig. 4 shows the flow chart of another the black liquid ejection control method in the ink-jet printer that fluid cartridge shown in Figure 1 is installed.In other words, the control circuit of inkjet printing pusher side of the present invention can be by the processing of the black liquid 4 of liquid ejection control method control injection shown in Figure 4.
At first, judge whether print cartridge 1 is installed to box mounting portion 2 (step S101).Be mounted if judge print cartridge 1, then begin the some counting of counting and calculating from the drop amount of the black liquid 4 of printhead ejection in print processing is handled (step S102).
Then, carry out to judge that handling the point whether count value that obtains reach default print cartridge 1 effective ink amount by a counting counts judgment processing (step S103).
If reach 100% (with the ratio of effective ink amount), then handle and advance to the step S104 that stops using print cartridge 1 as the ink terminal point in step S103 judging point count value.
If less than 100%, then handle and advance to next step S111 in step S103 judging point count value.
At step S111,, judge whether to satisfy and be used to detect that black liquid exists or there is or does not exist testing conditions in non-existent ink based on signal from ink end point sensor 13 output.For example, existence or the non-existent condition that is used to detect ink is whether the timing that infeeds/discharge paper, time-out printing work or beginning cleaning produces.By judging whether to be in default timing, judge whether to satisfy as carrying out and detect the ink existence that requires or do not have testing conditions.
If judge that at step S111 satisfying ink exists or do not exist testing conditions, then handle advancing to next step S112, wherein detect the existence of black liquid or do not have (there is judgment processing in black liquid) by ink end point sensor 13.
If judge that at step S112 black liquid exists, then the point in past is counted (step S113) continuously and this processing turns back to step S103.
On the other hand, if judge that at step S112 ink does not exist, then handle advancing to step S122.
At step S122, carry out predetermined some counting judgment processing, with judge judged black liquid do not exist after a some count value of counting and calculating whether reach predetermined some count value (corresponding to the some count value of cushion chamber China and Mexico liquid memory space).
If judge and to judge that the some count value of ink after not existing reaches default predetermined point count value (for example, effectively 10% of ink amount), then processing advances to the step S104 that stops using print cartridge 1 as the ink terminal point.
On the other hand, if judge and to judge that the some count value of ink after not existing do not reach the predetermined point count value, then the point in past is counted (step S123) continuously and this processing turns back to step S122.
According to ink discharge control method shown in Figure 4, in predetermined some counting judgment processing, judged black liquid after not existing the some count value counting and calculate (for example whether reach default predetermined point count value, effectively 10% of ink amount), reach predetermined some count value as the fruit dot counting, then stop using print cartridge 1 as the ink terminal point.
Therefore, be predetermined to be predetermined point value with corresponding some count value of cushion chamber 15 China and Mexico's liquid memory spaces, and after judging that black liquid does not exist, but by ink-jet printer with the allowed band of the 10% corresponding inking chamber China ink liquid memory space of print cartridge 1 effective ink amount in carry out the liquid inject process, change fluid cartridge then.Therefore, residual ink amount can be minimized in the fluid cartridge that abandons owing to changing, because the black liquid 4 in the cushion chamber 15 is almost by full consumption.
And, be set as equalization point count value if be used for effective ink amount of counting judgment processing in the consumption of general application state, and in addition as mentioned above, black liquid memory space in the cushion chamber 15 of print cartridge 1 for example is set as roughly 10% of effective ink amount, then also can prevent empty generation of spraying during repeating to change the situation of (promptly in use unload print cartridge 1 from ink-jet printer or reinstall) midway.
Black liquid memory space in the cushion chamber 15 is not limited to roughly 10% of effective ink amount of being held in the print cartridge 1 described in the embodiment.
For example, the black liquid memory space in the cushion chamber 15 also can be set as corresponding to ink-jet printer a piece of paper is printed standard consumption (printing amount of one page) in the operation.
So, in the situation of the print cartridge 1 that the black liquid memory space in cushion chamber 15 is set, obviously detect when not having black liquid residual when ink end point sensor 13, can still remain in the cushion chamber 15 that is arranged in fluid passage 9 ink inside end point sensors 13 downstreams the black liquid 4 that one page prints operation.
And, ink end point sensor 13 detect do not have black liquid residual after, therefore ink-jet printer can be finished the print processing of one page reliably.As a result, can prevent to use up black liquid 4 midway and cause this page or leaf not to be wasted owing to its print processing is finished in print processing.
And, do not have black liquid to carry out after residual to change print cartridge 1 then by detecting corresponding to the print processing of one page at ink end point sensor 13, can minimize residual ink amount in the print cartridge 1 that is dropped by replacing, because the black liquid 4 in cushion chamber 15 is almost by full consumption.
In addition, when ink end point sensor 13 detects when not having black liquid residual, be clear that with the corresponding black liquid 4 of print processing that carries out one page to remain in the cushion chamber 15.Therefore, can prevent that print processing subsequently from continuing to carry out absent-mindedly for a long time.So, can prevent from reliably to spray the shortcoming that causes by the sky of inkjet printing pusher side, should the sky injection be that lasting use causes under the empty state owing to the residue of ink liquid measure in print cartridge 1 is consumed fully wherein.
And, the corresponding capacity of maximum of the black liquid consumption (liquid-consumed amount) that consumes by ink-jet printer during the black liquid memory space in the cushion chamber 15 also can be set as and handle with the maintenance such as cleaning.
For example, cleaning is set as has three levels, and the ink amount that each level will consume is different.
Therefore, if being set as corresponding to its China and Mexico's liquid consumption, the black liquid memory space in the cushion chamber 15 has the cleaning of peaked level " 3 ", then obviously detect when not having residual black liquid when ink end point sensor 13, the black liquid 4 that can be used for the cleaning of executive level " 3 " remains in cushion chamber 15.Therefore, till ink end point sensor 13 detects when not having residual black liquid, can carry out its China and Mexico's liquid consumption reliably and have the cleaning of peaked level " 3 ".
For example, when ink end point sensor 13 detects when not having residual black liquid, the ink amount that remains in the cushion chamber 15 is clearly.Therefore, in the situation of not carrying out cleaning, preferably should after application consumed, change print cartridge 1 at once at residue of ink liquid corresponding to the print processing of wherein residue of ink liquid measure.Can prevent that print processing subsequently from continuing to carry out absent-mindedly for a long time.So, can prevent from reliably to spray the shortcoming that causes by the sky of inkjet printing pusher side, should the sky injection be that lasting use causes under the empty state owing to the residue of ink liquid measure in print cartridge 1 is consumed fully wherein.
In addition, black liquid memory space in the cushion chamber 15 also can be set as corresponding to such amount, the pre-filled volume of the black liquid 4 promptly being filled in from print cartridge 1 to the passage the printhead by ink-jet printer when print cartridge 1 is installed to the box mounting portion 2 of ink-jet printer.
Print cartridge 1 according to the black liquid memory space in such setting cushion chamber 15, obviously detect residue of ink liquid when not existing when ink end point sensor 13, the corresponding black liquid 4 of pre-filled volume when being installed to ink-jet printer remains in the cushion chamber 15 that is arranged in fluid passage 9 ink inside end point sensors 13 downstreams.
Therefore, therein when print cartridge 1 in use once when ink-jet printer unloads ink end point sensor 13 do not detect the state that does not have residue of ink liquid, can prevent that the residue of ink liquid measure in the print cartridge 1 from being consumed empty fully, therefore initial filling can be carried out safely, and simultaneously, even when print cartridge 1 is installed to the box mounting portion 2 of ink-jet printer once more, carry out initial the filling, also can prevent empty generation of spraying.
And when ink end point sensor 13 detects residue of ink liquid when not existing, residual ink amount is clearly in the cushion chamber 15.Therefore, in the situation of initially not filling, preferably should change print cartridge 1 at once after consumption and the corresponding residue of ink liquid of pre-filled volume in addition adopting normal process.As a result, can prevent that print processing subsequently from continuing to carry out absent-mindedly for a long time.So, can prevent from reliably to spray the shortcoming that causes by the sky of inkjet printing pusher side, should the sky injection be that lasting use causes under the empty state owing to the residue of ink liquid measure in print cartridge 1 is consumed fully wherein.
And the black liquid memory space in the cushion chamber 15 also can be set as the residue of ink liquid measure (the residual solution scale of construction) of forbidding being undertaken by ink-jet printer the reference of the maintenance processing such as cleaning corresponding to conduct in the print cartridge 1.
In the situation of the print cartridge 1 of setting like this cushion chamber 15 China and Mexico's liquid memory spaces, when ink end point sensor 13 detects residue of ink liquid when not existing, residual ink amount is clearly in the cushion chamber 15.Therefore, in the situation that the maintenance that does not have execution such as cleaning is handled, preferably should change print cartridge 1 at once after consumption and the corresponding residue of ink liquid of residue of ink liquid measure in addition adopting print processing.As a result, can prevent that print processing subsequently from continuing to carry out absent-mindedly for a long time.So, can prevent from reliably to spray the shortcoming that causes by the sky of inkjet printing pusher side, should the sky injection be that lasting use causes under the empty state owing to the residue of ink liquid measure in print cartridge is consumed fully wherein.
For example, can the black liquid memory space in the cushion chamber 15 (capacity that comprises the fluid passage 9 between ink end point sensor 13 and the pressure controlling device 11) suitably be set by capacity that changes cushion chamber 15 or the position that changes installation ink end point sensor 13 in the fluid passage 9.
And, be set as at black liquid by the determined low ink time period of the black liquid memory space in the cushion chamber 15 and have the longest timing that detects in the judgment processing under the frequency that ink exists.As a result, can prevent to detect the print cartridge 1 actual ink terminal point that becomes when not having residue of ink liquid at ink end point sensor 13.
