Description

A kind of stylus-regulating method that increases the printer port of printer life-span

The present invention relates to the print-out method of printer, relate to adjust the needle method that of printer prints pin or rather.

All kinds of printers of current popular are when printing transverse meter line, all be to adopt 1 fixing pin or 2 stylus printers seal, as single line with the 12nd stylus printer print, two-wire prints with the 12nd, 13 stylus printers, thereby through being usually used in the printer of duplicate printing form one class file, the pin number of times that goes out of its 12nd, 13 pin substantially exceeds other pins.Yet fix the service life of printhead, be generally 200,000,000 times/pin, therefore often the pin that uses will wear and tear even rupture at first, and when printhead the broken needle situation occurs and can't repair a period of time, then can only be no matter printer prints goes out the printing sample of poor quality.

The objective of the invention is to design a kind of stylus-regulating method that goes out that increases the printhead bulk life time, can use each root pin effectively, equably, and can occur still guaranteeing print quality under the situation of broken needle, because the printhead price generally accounts for about 1/3 of printer price, therefore implementing this method has considerable benefit.

Method of the present invention is a kind of method that printhead goes out pin of adjusting, the pinwheel that comprises printhead changes impact system and broken needle penalty method, promptly utilize the whole pins or the part pin of printhead to print by turns automatically originally by the transverse meter line of the 12nd, 13 stylus printers seal with when broken needle occurring, call near the former data that should print by broken needle of the normal stylus printer seal broken needle, owing to be each the root pin that on average uses printhead, can prolong the whole service life of printhead effectively, when printhead has broken needle, can call pin again in time and replace, keep normal printing effect.Method of the present invention is applicable to that 9 pins, 24 pins reach the printer greater than 24 pins.

The operating procedure that the present invention's 24 pinwheels change impact system is:

1) in printer, sets up the read-only memory EEPROM that the memory user is provided with, use guidance panel, pinwheel is set changes printing model;

2) start is printed the pin number of transverse meter line read last shutdown from EEPRM before, and is rotated to next pin number, and this pin number of printing transverse meter line is recorded among the EEPROM;

3) this is printed the pin number number n of transverse meter line and 12 works greater than, less than, equal comparison;

4) making normal data during n=12 handles and prints;

5) n＞12, calculate y=n-12, the reverse micro-paper feeding y line of elder generation, again tab dot array data 24 lines that read are made logic shift right integral body and move down the y line, the tab dot array data is adjusted earlier corresponding to y+1 pin to the 24 pins from the 1st line to the 24-y line and is printed once, forward trace paper feeding y line is got tab dot array data the 25th-y line to the 24 lines and is adjusted printing more once corresponding to the 25th-y pin to the 24 pins of printhead again;

6) X=12-n is calculated in n＜12 o'clock, reads tab dot matrix first line to X line data, prints once earlier to the X pin corresponding to printhead the 1st pin; Forward trace paper feeding X line is got whole 24 lines of tab dot array data and is done to move X time on the logical shift left; Adjust printing more once from the X+1 line to 24 lines corresponding to the 1st to the 24th-X pin.

If 9 needle printers then change 24 in the

step

5,6 into 9, change 12 in the

step

3,4,5 into 5, and can this be extrapolated to the printer of any pin number.The operating procedure of broken needle penalty method of the present invention is:

1) in printer, set up the read-only memory EEPROM that the memory user is provided with, use guidance panel, the broken needle compensation model is set,

2) guidance panel is provided with broken needle pin number number n and n is recorded among the RAM;

3) get the normal earlier printing of dot array data once;

4) get the broken needle pin number number n of setting, when 2≤n≤24, forward trace paper feed 1 line with moving 1 line on the n needle location data, compensates printing once again with n-1 pin; When n=1, reverse micro-paper feed 1 line moves down 1 line with the 1st needle location data, compensates printing more once with the 2nd pin.

Further specify method of the present invention below in conjunction with STAR series impact printer (comprising AR3200, CR3240, CR3240-II, AR4400), implementation method comprises the compensation method for broken when 10 pinwheels change impact system, 24 pinwheels and change impact system and disconnected 1 pin, disconnected 2 pins, and wherein 10 pins, 24 pinwheels change impact system and all are applicable to and print the tab horizontal line.
