(3) adopt circulation printing compensation mode, mean allocation compensation print out task;
(4) when occur can not single compensation the broken needle combination, adopt and seek continuous 12 or two and be spaced apart 66 good stylus printer seal, realize twice printing.
The present invention writes down the broken needle sequence number after detecting broken needle, judged whether broken needle, need to carry out the broken needle compensation? there is not broken needle, the normal printing; Otherwise change and judge whether it is to finish printing with once compensating;
Calculate the alternative pin sequence number that this compensation is used, and substitute the stylus printer printing according to generation;
Need to have judged whether the compensation print data, had then to compensate print processing, do not had and then directly withdraw from; When needing compensation to print,, will substitute pin and move to the broken needle position according to the alternative pin sequence number location of entering a new line; Compensate printing;
Line feed navigates to the compensation front position; Write down alternative pin that this compensation print to use number, the compensation of being convenient to next time circulate is calculated and is used; Do you judge that preceding 12 pins have print data? print, directly do not enter and judge back 12 pin programs;
The line feed location moves to preceding 12 pin positions with 12 continuous pins, prints preceding 12 pin data with 12 continuous good stylus printers;
Do you judge that back 12 pins have data? have then to compensate printing, then directly do not withdraw from;
The line feed location moves to back 12 pin positions with 12 continuous pins; Print back 12 pin data with 12 continuous good stylus printers; One line printing ends.
Characteristics of the present invention are: propose the method that a kind of new printer detects the compensation of automatic setting broken needle automatically.Compensation making is more convenient, and it is more reasonable that compensation is printed, and compensation range is more extensive.
1. realized first that the printer broken needle detects the function of automatic setting automatically.By operation printer trace routine, utilize optical pickocff or pressure sensor automatically the print needle quality to be judged, and record broken needle situation.Having made things convenient for operating personnel to carry out broken needle sets.
2. adopted the more compensation Method of printing of science: the circulation penalty method, promptly utilizing many intact print needles that broken needle is carried out many-to-one circulation compensation prints, the workload equilibrium of broken needle is assigned on other compensation pins, improve the utilization rate of each pin of printhead, avoided using the caused too fast wear problem of single compensation pin simultaneously.Before the compensation process of the present invention in addition, can judge whether the broken needle of setting has print data, not have can not compensate printing under the data conditions maximum raising print speed.
3. the expansion of compensation range, maximum 3 broken needles of compensation of supporting, wider user's request has been satisfied in the reinforcement of function, in addition for improving the compensation printing effect, when two above broken needles can not carry out the single compensation printing, adopt new compensation Method of printing, both carried out twice printing, finish print out task by seeking continuous 12 good pins.
