Clean master control part 52 according to setting normal developing pattern Drive and Control Circuit 56, trace rinse mode Drive and Control Circuit 57, attract the selectivity starting of ejection pattern with the condition of drive circuit 58, as one of this action, sending from master computer when being used to print the print data of action, the increase of the instrumentation time of cleaning elapsed time timer 53 instrumentations of corresponding this moment and by micro-cleaning model with Drive and Control Circuit 57, conventional cleaning model Drive and Control Circuit 56, attract the ejection pattern to use the select progressively ground of intensity control circuit 58 to start any one, make wiper mechanism 59 clean action.In cleaning master control part 52, the condition of the control circuit of starting is set arbitrarily when being used to select to clean action, the instrumentation time of cleaning elapsed time timer 53 instrumentations reaches the stipulated time when above, setting is no matter having or not of printing also can be started attraction ejection pattern Drive and Control Circuit 58, and 59 settings comprise that attracting to spray the cleaning of moving moves to wiper mechanism.In addition, in the present embodiment, the described stipulated time is set at 360 hours.
In addition, when before printing action at the appointed time, corresponding to by the instrumentation time of cleaning elapsed time timer 53 instrumentations, before printing, carry out slight cleaning action with Drive and Control Circuit 57 or normal developing pattern with Drive and Control Circuit 56 by micro-rinse mode.This slight cleaning action with comprise the cleaning action that attracts the ejection action compare the time compole of needs short and with comprise obvious difference of cleaning action that attracts the ejection action.
In addition, clean master control part 52 the printing release of being undertaken by printhead 21 and to after printing cut off action automatically with paper 11a after, judge whether the instrumentation time of cleaning elapsed time timer 53 instrumentations reached more than the judgement time of the time set before the described stipulated time, reach this judgement time when above when the instrumentation time, set and attract the ejection pattern to make it to start with Drive and Control Circuit 58.In addition, in the present embodiment, described judgement time set is 350 hours than 10 hours in advance described stipulated time.
Below, with reference to the head maintenance method of the flowchart text present embodiment of Fig. 6.
After the printing carried out at printhead 21 action finished fully, the part after printing with paper 11a was when sending with paper distribution mouthfuls 6, by the automatic cut-out action length cut-out paper 11a in accordance with regulations of automatic cutter.To be somebody's turn to do and cut off the program (step S01) of action (AC action) automatically as the action of trigger starting head maintenance.Thus, clean master control part 52 and judge at first whether the instrumentation time (CL elapsed time T1) by cleaning elapsed time timer 53 instrumentations reaches the described judgement time (350 hours) above (step S02).
At step S02, be lower than judgement during the time when the instrumentation time of judging by cleaning elapsed time timer 53 instrumentations, comprise the EP (end of program) (step S03) that attraction China ink and the head maintenance that moves from the attraction ejection of ink nozzle ejection move, printhead 21 returns holding state simultaneously.
In this case, clean the increase of the instrumentation time of elapsed time timer 53 instrumentations corresponding this moment, start micro-cleaning model Drive and Control Circuit 57 or conventional cleaning model Drive and Control Circuit 56, lettering below carries out before trace cleaning or conventional the cleaning, omits this explanation and only illustrate at this to comprise that attraction sprays the cleaning of action.
At step S02, in the instrumentation time of judge cleaning elapsed time timer 53 instrumentations is that the judgement time is when above, clean master control part 52 startings and attract the ejection pattern, make wiper mechanism 59 comprise the cleaning action (step S04) of attraction ejection action with Drive and Control Circuit 58.
After the cleaning release of step S04, cleaning master control part 52 will be cleaned and is stored in the finish time in the memory 55, the instrumentation time (CL elapsed time T) of cleaning elapsed time timer 53 is resetted, stop the program (step S05) of head maintenance action, printhead 21 returns holding state simultaneously.
The program of the head maintenance action by implementing present embodiment, after the printing release that printhead 21 carries out, before comprising, once attract elapsed time after the cleaning release of ejection action to reach the judgement time when above, comprise the cleaning action that attracts the ejection action.Therefore, after after preceding once cleaning action stops, stopping the printing action under the process state of judgement time, the timing that does not wait print beginning next time is just directly cleaned action, if and, then when printing beginning next time, just do not clean action for this cleans release afterwards through before the stipulated time.
Promptly, if the preceding holding state that does not continue not print more than the stipulated time action after the release of once printing, then preceding once clean release after through the cleaning action after printing before the stipulated time, and the cleaning action when not printing beginning.Thereby, by when printing beginning, implementing to clean action, can avoid in fact beginning the definite time delay printed, and reduce to and print the stand-by period that finishes, improve handling capacity.And whenever just clean action through the judgement time roughly, therefore can make ink nozzle maintain good state.
Especially when waiting by the automatic cashier in supermarket, use under the situation of printer 1 in the printing of the discount gift token of commodity etc., can be in cashier's actuarial process or after the actuarial, do not need the time of long wait and Print Gift Certificate and distribution by cleaning to move, therefore, not only client need not wait for, and aspect the cashier, can shorten the on average time of each customer need, therefore can improve the efficiency of cashier's work.
In addition, as shown in Figure 6, with different as the situation of trigger with automatic cut-out action, do not printing action, and do not comprise under the state of the cleaning action that the attraction ejection of printhead 21 is moved, when reaching the described stipulated time (360 hours) (step S06) by the instrumentation time of cleaning elapsed time timer 53 instrumentations, with this as trigger, the 52 preferential startings of cleaning master control part attract ejection patterns Drive and Control Circuit 58, thereby make wiper mechanism 59 comprise the cleaning action (step S04) of attraction ejection action.
Like this, under the state that the cleaning release printing action afterwards that once attracts ejection to move before comprising is not carried out, during through described stipulated time, the printing that does not wait next time begins to attract to spray the cleaning action that action is moved with regard to preferentially comprising, also can not reach the described stipulated time even do not clean the time maximum of printhead 21 thus.Thereby, can make ink nozzle maintain good state frequently, and can prevent that print qualities such as stop omission are low.
Below, second embodiment of the invention is described.
In first embodiment of the invention described above, to attract the spray volume in the ejection action to be made as a certain amount of, but in second embodiment,, the stipulated number of each attraction ejection attracts ejection because passing through stronger attraction, thus, conventional attraction ejection action is carried out with suitable intensity, and can be suppressed consumption as the China ink of total amount.
Secondly, describe with accompanying drawing etc.About figure and explanation, give same-sign and omit its explanation for member etc. identical with above-mentioned embodiment or that have a same function.
In the first embodiment, timer 54 is printed in the accumulation that is provided with the accumulation time-write interval that instrumentation printhead 21 carries out, and in second embodiment, also be provided with the cleaning cumulative frequency counter 60 that the cumulative frequency that the cleaning that attracts the ejection pattern to carry out with Drive and Control Circuit 58 actions is moved is counted.(chain-dotted line among Fig. 5).
Then, with reference to Fig. 5 wiper mechanism 59 that is used to clean printhead 21 and the head maintenance device 51 that is used to control the action of this wiper mechanism 59 and comprise cleaning control portion 50 are described.
Clean cumulative frequency counter 60 and calculate when printer 1 power supply is opened for the first time and attracting to implement to clean the cumulative frequency of action under the ejection pattern, this cumulative frequency is used to be cleaned master control part 52 and does reference when decision attracts the traffic attraction of ejection action China and Mexico promptly to attract to spray the intensity degree of action.In addition, be stored in memory 55 one by one by the cumulative frequency that cleans 60 calculating of cumulative frequency counter.
Below, describe with reference to the flow chart of Fig. 8 head maintenance method present embodiment.In described first embodiment, so that wiper mechanism 59 comprises the instruction of the cleaning action (step S04) that attracts the ejection action as trigger, the program (step S11) of starting head maintenance action.
Cleaning master control part 52 decisions makes wiper mechanism 59 comprise intensity degree (the CL parameter adjustment: step S12) that the attraction ejection when attraction sprays the cleaning action of moving is moved.Attract the intensity degree correspondence of ejection action to set by the black residual amount of cumulative frequency that cleans 60 calculating of cumulative frequency counter and print cartridge 17.
Then, the IC chip access of print cartridge 17 also detects the residual amount of versicolor China inks in the print cartridge 17, and whether the black consumption when being used in intensity degree that step 12 sets and cleaning action reaches the calculating in advance of end of China ink, and (CL judges in advance: step S13).In addition, in this CL judges in advance, also detect the waste liquid amount in the print cartridge 17, and whether reach more than the allowance and calculate in advance when cleaning action, storing waste liquid amount in print cartridge 17.
After the CL that carries out step S13 judged in advance, whether at least one that judge black end or waste liquid surplus had made wrong judgement (step 14).And, in step 14, when being judged as the mistake judgement, support 23 is disposed at position of readiness, and by the ink nozzle covering (CR close adjustment: step 17) of cap 27 with printhead 21, simultaneously, carry out showing the mistake processing (step S18) that becomes black end or waste liquid surplus at display part 112 (display lamp 41～44).
On the other hand, in step S14, do not have wrongly when judging being judged as, clean master control part 52 and be used in parameter starting that step S12 sets and attract the ejection pattern with Drive and Control Circuit 58, wiper mechanism 59 is comprised attract the cleaning action (step S15) of ejection action.
After the cleaning release of step S15, cleaning master control part 52 will be cleaned and is stored in memory 55 finish time, and the instrumentation time (CL elapsed time T1) that will clean elapsed time timer 53 resets, increase a reading that cleans cumulative frequency counter 60, the program (step S16) that stops the head maintenance action simultaneously, printhead 21 returns holding state.
At this, the CL parameter adjustment program of step 12 is described with reference to Fig. 9.And the CL parameter is to set the step number of the motor of the black suction pump that mainly drives China ink attraction mechanism 29.
The step S12 of acceptance pattern 8 and begin parameter adjustment (step S41).And, at first with reference to cumulative frequency, judge whether to reach the multiple (step S42) of the number (being 8 in the present embodiment) of regulation by the cleaning action of cleaning cumulative frequency counter 60 countings.
In step S42, when the cumulative frequency that is judged as the cleaning action is not 8 multiple (step S42:No), adjust the parameter of cleaning level 1.The cleaning level is the intensity of this attraction ejection action, and the attraction spray volume (black consumption) by printhead 21 is according to level and difference.Cleaning level 1 is the level that conventional attraction ejection is moved, and will be set at cleaning level 2 than its strong a little attraction ejection action, closes choke valve, will lean on strong negative pressure to attract the moving cleaning level 3 that is set at of ejection.
At step S42, when the cumulative frequency that is judged as the cleaning action is 8 multiple (step S42:Yes), corresponding black residual amount is set cleaning level 1～3.Also have, black residual amount is distinguished and is judged as ink-condition 0～4 five stage, and ink-condition 0 is the maximum level of black residual amount, and its following black residual amount is set by the order that reduces, the level of black situation 4 for judging that China ink is terminal.At first, shades of colour is judged whether to meet the China ink (step S43) of the less black situation 2 of black residual amount, when the color of black situation 2 was arranged, the parameter of cleaning level 1 just was adjusted (step S44).
At step S43, when being judged as the color that does not have black situation 2, judge whether to meet the China ink (step S45) of black residual amount than the black situation 1 of black situation more than 2 to of all kinds, when the color of black situation 1, the parameter of cleaning level 2 just is adjusted (step S46).
At step S45, when being judged as the color that does not have black situation 1, the parameter of cleaning level 3 just is adjusted (step S47).
Like this, when the cumulative frequency of cleaning action reaches the multiple of stated number, promptly carry out the cleaning action stronger than other situation in the corresponding black residual amount of number of times of each regulation.Thereby, when cumulative frequency was not the multiple of stated number, the state of guaranteeing ink nozzle was moved in the cleaning that suppresses the consumption of China ink and carry out suitable intensity, carried out strong cleaning action at the number of times of each regulation, adjust the state of ink nozzle, make ink nozzle maintain good state.
In addition,, also can corresponding black residual amount select the cleaning action of suitable intensity, therefore, carry out the cleaning action of suitable intensity, make to prevent that China ink from reaching terminal, and do not use up the China ink of supplying with printhead 21 even reach at cumulative frequency under the situation of multiple of stated number.
As described above, head maintenance method, head maintenance device 51 and printer 1 according to present embodiment, before for the stipulated time of cleaning the action setting, comprise the cleaning action that attracts the ejection action in the timing of printing after finishing, therefore, by implement to clean action when printing beginning, can avoid beginning in the reality to print is hysteresis regularly, print the stand-by period that finishes thereby reduce to, improve handling capacity.
Also have, the invention is not restricted to above-mentioned embodiment, can carry out various changes.For example, be example with the ink-jet printer, also applicable to device and method from shower nozzle ejection China ink liquid in addition.
In addition, though represented to clean the example that elapsed time timer 53 instrumentation wiper mechanisms 59 finish the previous cleaning action elapsed time afterwards, but also can be with a clear instruction is the trigger instrumentation, but be preferably, even in cleaning course of action, any mistake is arranged, also can after cleaning release, carry out desirable cleaning reliably.
In addition, to the power supply that do not cut off printer and be described with situation that main frame always is connected, but for cutting off printer power supply and cut-out situation about being connected with main frame, at the enable printer power supply, the elapsed time of being calculated by cleaning elapsed time timer 53 surpasses under 360 hours the situation of official hour, also can comprise the cleaning of ejection action fast.
