Description of drawings
In order to understand the present invention better, see also accompanying drawing and to the narration of preferred embodiment, wherein,
Fig. 1 is the schematic diagram of one group of nozzle of ink jet-print head.
Fig. 2 is the dot matrix schematic diagram of not having an error-correction operation that Fig. 1 printhead forms.
Fig. 3 is the dot matrix schematic diagram same as shown in Figure 2 that is formed by Fig. 1 printhead, but has error-correction operation.
Fig. 4 dot matrix schematic diagram of not having an error-correction operation that to be another formed by Fig. 1 printhead.
Fig. 5 is the identical as shown in Figure 4 dot matrix schematic diagram that is formed by Fig. 1 printhead, but has error-correction operation.
The specific embodiment
As shown in Figure 1, printhead 10 has one group of nozzle 12 array that is in line.For convenience of explanation, only show 14 nozzles among the figure, in fact delegation's nozzle can comprise dozens of, thousands of nozzle.Paper along the direction that is basically perpendicular to nozzle line from printhead below by, as shown in arrow 14.Printhead can be fixed, and also can be movably.When paper below printhead through out-of-date, nozzle A to N optionally prints to an ink dot matrix on the paper as required.This array is made up of a series of row and column, and the distance between them is respectively by distance between the nozzle and the decision of minimum paper feed step-length.Though preferred vertical and horizontal point distance should equate, because the mechanism of command range is different, so not necessarily can realize.Printhead can use page width printing head or the less printhead along paper scanning, to stipulate a series of landscape orientation bands.
For convenience of explanation, suppose that nozzle a-g and i-n can operate as normal, and nozzle h cisco unity malfunction or do not work fully for a certain reason.Simultaneously, the diagnostic system (those skilled in the art will be appreciated that) of supposing printer has detected nozzle h cisco unity malfunction.Usually, it mainly is because nozzle is partly or entirely stopped up that nozzle is not worked, thereby causes print point China ink quantity not sufficient even inkless.
Fig. 2 be by printhead 10 print not with the schematic diagram of a part of print job of error correction,
A blank column is wherein arranged, with " h " mark, corresponding nozzle h, and row a-g and i-n are correctly selected to print.According to printhead 10 is page width printing head or scan-type printhead, and this will cause occurring one or more stray line in print job.Label is that 16,18,20 and 22 the round representative that is not coated with shade should print to row h, and not have the ink droplet in the printing.Fig. 3 is the same image of being printed by printhead 10, but it is through the present invention one
The correction process of embodiment.
As mentioned above, paper is along the direction process printhead of arrow 14, so that row 1 is at first printed.In the row 1, row h place should print point 16.Because whether nozzle h cisco unity malfunction needs printed dots so control system is judged adjacent nozzles g and i.Because these two nozzles do not need printed dots, so control system is partly selected one randomly any is placed this respective column rather than row h from row g and row i.
Control system is alternately printed extra ink droplet in the both sides of defective nozzle usually, so preferred print position should be the opposite side of the ink dot of printing last time.Certainly data conditions before also existing not, for example: just detecting after this nozzle breaks down, or printer is when being restarted.In this case, control system will be chosen in left column or right row printing at random.
Because row g and row i are " vacant ",, control system prints single ink dot so, being chosen in position g according to mentioned above principle.
On row h, do not have a little in the row 2, so do not need to increase extra point.
Need have 1: 18 on the h at row in the row 3, and row g and row h be vacant, because the additional point of printing last time (being expert at 1) is to be printed among the row g, therefore, current additional ink dot printing is at row i.
On row h a print point 20 is arranged also in the row 4, still, specifically, row g and row h require a bit.There is not extra ink dot so be expert in 4.And in the row 5, row h does not require print point, and row g is vacant with row i.Because a last additional ink dot printing is at row i, so select row 5, row g to print in the original plan and be expert at 4, the point of printing among the row h.
Requiring in the row 6 also has a print point 22 on row h, but current, and row g and row h are occupied again.So, needing to next line, row 7 is printed extra ink dot.In the row 7, row h and row g do not plan print point, still, a plan print point are arranged among the row i.Can recall, some 20a is printed on row g, so the optimum position of current extra ink dot 22a should be row i.But this position is no longer idle, thus this point can only be printed on row g, though this can cause next extra ink dot still to need to print among the row g.Though this can seem uneven on microcosmic, say still to be balanced on the macroscopic view.
Fig. 4 and Figure 5 shows that two groups of print jobs, on average, they are more than point that Fig. 2, Fig. 3 need.Here, still suppose nozzle h cisco unity malfunction.At first print line 1, needs print point 30 among the row h.Owing to have only the row g free time, some 30a is printed on row g.The row h of row 2, row 3 needs to print a point, but because row g is unavailable, all is printed among the row i with some 34a so put 32a, and no matter to replacing " needs " of printing.
Row 4, row 6 do not need a little, but row 5, row 7 need a little.Owing to have only delegation to use, some 36a and some 38a print to respectively among capable g and the row i.
In addition, the present invention can also print the large scale ink dot in adjacent or close with unprinted position non-moving position, and/or print extra ink dot between the row adjacent or close with unprinted position.This starts adjacent out of order nozzle usually by the control device of printer operation printing nozzle is embodied as or prints a little bigger or with the corresponding printing system of upper frequency print point.
Although the technology of Jie Shaoing is only considered the row in the back printing of former row when determining where to place ink dot here, be appreciated that and see before using that feature places the former row before that begins with point.For example: if according to after see criterion, point should be placed the right side of defective nozzle; If but before see that will find that ensuing several provisional capitals need printed dots in these row, so, better solution is exactly the left column that ink dot is printed on former row.Equally, this embodiment also can move to next line with point.See feature before the utilization, the dot printing that can will require according to the needs of printing effect to print is to requiring position row before usually.
In addition, the present invention's digital printer that also can cooperate laser printer, LED printer, copying machines and other to utilize parts independently to print different ink dots uses jointly.For example, in the LED printer, certain LED may go wrong; In laser printer, certain photosensitive imaging drum may go wrong.In both cases, the defective that equipment fault produces can be hidden or alleviate to transfer point, improves the visual effect of image.
