Bearing calibration is titrated to facilitate a better understanding of above-mentioned inkjet print head, is carried out combined with specific embodiments below detailed
Explanation.
Before entire inkjet print head starts to carry out ink droplet correction, force to carry out a Xiang Chengxu: selection nozzle 1 first carries out
Ink-jet, it is ensured that the case where grasping nozzle 1 before entire inkjet print head carries out ink droplet correction avoids titrating in inkjet print head
In correction course, because that cannot identify that nozzle 1 is actually that the situation blocked causes ink droplet titration timing that ink droplet dislocation occurs
It is abnormal.Operator can be allowed to grasp the situation out of ink of nozzle 1 in advance, prevent artificial maloperation, carry out checking mistake to reduce
Time cost accidentally.

After focal imaging adjustment, the ink droplet correction of 128 nozzles of entire inkjet print head is carried out after record position.
Second situation, if nozzle 1 does not spray ink droplet (can specify nozzle 1 to be possible to block), then it is assumed that first
Ink droplet is not that first jet sprays, that carries out ink-jet movement with regard to selection nozzle 2 to nozzle 4 (small number), if result confirms nozzle 2
Ink droplet can be sprayed, that means that ink droplet can be attributed to the progress coordinate position record of nozzle 2 at first on computer interface, keep away
Exempt from that ink droplet at first on computer is accidentally carried out coordinate position record as nozzle 1；If result confirmation nozzle 2 cannot spray ink
Drop, then it is assumed that the first ink droplet is not that nozzle 2 sprays, then executes ink-jet movement to nozzle 3, confirms nozzle 3 according to ink-jet result
Coordinate value；Until determining the first ink droplet and spraying the nozzle location of the first ink droplet, and by the position of the first ink droplet and the nozzle position
Correspondence is set, then carries out subsequent correction process.
It should be noted that it is a kind of situation that * 1 place's nozzle 2, which sprays ink droplet, in Fig. 2, it is also possible to nozzle 2 occur and also do not spray
Out, final purpose be find out nozzle corresponding to first ejection ink droplet number be mutually correctly；* 2 places have defined in Fig. 2
