As shown in figure 17, in carrier unit 100, reclaim pump 116 midway at the waste liquid that is provided with of the stream that is communicated with waste liquid returnable 17 and waste liquid recycling can 102.This waste liquid reclaims pump 116 to have than the high ability (capacity) of pipe pump 20 that is arranged in the movable ink jet unit 10.
Make by waste liquid recycling can linkage unit under waste liquid returnable 17 and the state that waste liquid recycling can 102 fluids are communicated with, can reclaim pump 116 by waste liquid and attract the waste liquid in the waste liquid returnable 17 and it forcibly is discharged in the waste liquid recycling can 102.
As shown in figure 17, ink jet unit 10 has printing control unit 50, by this printing control unit 50 control carriage 11 reciprocating action, attract unit 16 to attract to discharge the action etc. of inks from record head 12 from ejection action, the ink of record head 12 ejection ink droplets.
In addition, printing control unit 50 comprises: consumption memory cell 51, the consumption of the liquid in the storage ink tank 14; And discharge rate memory cell 52, storage is to the discharge rate of the waste liquid of waste liquid returnable 17 discharges.
On bracket side control module 120, be connected with: supply positioning indicator 123, the situation that report has been finished to ink tank 14 ink feeds; And reclaiming positioning indicator 124, the situation of the waste liquid in the waste liquid returnable 17 has been reclaimed in report by waste liquid recycling can 102.
In ink tank 14, be provided with the quantity of ink detecting unit 53 that the quantity of ink in its storage area 13 is detected.This quantity of ink detecting unit 53 can detect the situation that the quantity of ink in the storage area 13 of ink tank 14 have been full of at least.
The time point that quantity of ink in the storage area 13 that detects ink tank 14 by quantity of ink detecting unit 53 has been full of, ink feed control module 121 is closed ink replenishing valve 126 and is finished to ink tank 14 supply inks by 123 reports of supply positioning indicator simultaneously to ink tank 14 supply inks stopping from China ink jars 101.
Waste liquid reclaim control module 122 after waste liquid reclaims pump 116 startings through the time point of stipulated time stop waste liquid and reclaim pump 116, finish waste liquid and reclaim by reclaiming positioning indicator 124 report waste liquid returnable 17 simultaneously.Perhaps, the unit that detects the amount of liquid in the waste liquid returnable 17 can be set, stop waste liquid according to signal and reclaim pump 116, and make 124 actions of recovery positioning indicator from this detecting unit.
Then, illustrate that the ink feed action and the waste liquid that are carried out when the ink jet unit 10 that is in the state of can removing is formed as one with carrier unit 100 reclaim action.
When detecting ink jet unit 10 by above-mentioned integrated detecting unit 117 when having become one with carrier unit 100, this detection signal is sent to bracket side control module 120.
The bracket side control module 120 that receives integrated detection signal reclaims control module 122 by ink feed control module 121 and waste liquid and begins ink feed action and waste liquid recovery action.
That is, ink feed control module 121 is opened the ink replenishing valve 126 that often is in closed condition after receiving integrated detection signal.So China ink jar 101 interior inks flow in the ink tank 14 under the effect of gravity.
And when being detected quantity of ink in the ink tank 14 by quantity of ink detecting unit 53 when having become the amount of being full of, ink feed control module 121 is closed ink replenishing valve 126, and finishes by supply positioning indicator 123 report ink feeds.At this moment, the memory (memory) of the consumption memory cell 51 of printing control unit 50 is reset.
Waste liquid reclaims control module 122 and receives integrated detection signal and make waste liquid reclaim pump 116 actions.Here, reclaim the time point of pump 116 actions at waste liquid, the printing control unit 50 by ink jet unit 10 makes pipe pump 20 become non-connected state.That is, flexible pipe 21 is flattened by the pulley 22 of pipe pump 20, thereby makes stream be maintained blocked state.
Like this, when making waste liquid reclaim pump 116 actions under the state that is maintained non-connected state at pipe pump 20, the inside of the container body 40 of waste liquid returnable 17 becomes negative pressure, along with discharging ink from waste liquid returnable 17, flexible pot shape parts 42 distortion, the internal capacity of container body 40 reduces, and ink absorber 43 shrinks.Thus, absorb the ink that keeps by ink absorber 43 and twisted out, thus the waste liquid in the effluent discharge returnable reliably 17.
When after action that waste liquid reclaims pump 116 begins, having passed through the stipulated time, remove the collapsed state of the flexible pipe of realizing by the pulley 22 of pipe pump 20 21, make and manage pump 20 and become connected state.
Then, stop waste liquid and reclaim pump 116, stop to attract the action of effluent discharge from waste liquid returnable 17.Simultaneously, finish to waste liquid recycling can 102 recovery waste liquids from waste liquid returnable 17 by reclaiming positioning indicator 124 reports.At this moment, the memory of the discharge rate memory cell 52 of printing control unit 50 is reset.
