Abstract
The invention relates to a control method for recovering defects of dot-matrix typed printing equipment. The method divides the printing head of the dot-matrix typed printing equipment into n printing point modules in the height direction from top to bottom; when defects occur to the printing characters, the i-th printing point module where the defect occurs is shielded and the j-th printing point module which is closest to the i-th printing point module and has no defect is used for replacing the printing operation which is supposed to be completed by the i-th printing point module. The method not only can ensure the printing quality without replacing the printing head, has strong practicability, but also prolongs the service life of the printing head, saves the use cost and has good use effect.
Description
Technical field
The present invention relates to a kind of control method of defect recovery of lattice type typing equipment.
Background technology
In the prior art, impact printer is applied to the data printing of professional domains such as document, invoice, form widely.Because impact printer work under bad environment, working time are long, print media is more rough, causes the printhead broken needle easily, makes print quality decline.But the user often feels simply helpless under the situation that can't change for the moment printhead urgent need assurance print quality.And the frequent replacing of printhead also can cause unnecessary waste, has increased the cost consumption of impact printer in daily use.
Summary of the invention
The object of the present invention is to provide a kind of control method of defect recovery of lattice type typing equipment, this method not only can guarantee the lettering quality under the situation of not changing print head, practical, and prolonged service life of print head, and saved use cost, result of use is good.
The technical solution used in the present invention is: the control method of this defect recovery of lattice type typing equipment is divided into n print point module with the print head of lattice type typing equipment from top to bottom along the font height direction, and carries out defect recovery work as follows:
(1) detects the lattice type typing equipment lettering and shortcoming whether occurs, if then start the defect recovery function;
(2) if started the defect recovery function, then mask that print point module that the shortcoming situation occurs, be made as i print point module, the height of described i print point module is Hi;
(3) find from i nearest and impeccable j the print point module of print point module, if the total height of all print point modules is H between i print point module and j the print point module, print head and printing paper are done relative motion along the font height direction, the relative motion distance is (Hi+H), so that j print point module is positioned at original i residing operating position of print point module;
(4) replace i print point module printing note to need i the lettering content that the print point module is finished with corresponding print point in j the print point module;
(5) print head and printing paper are done rightabout relative motion along the font height direction, so that print head is got back to normal operation position;
(6) detect whether also to have other shortcomings, if having then return step (2); If no, then print remaining lettering content with other print point modules that shortcoming do not occur;
(7) the lettering task of carrying out other normal flow is handled.
The another kind of technical scheme that the present invention adopts is: the control method of this defect recovery of lattice type typing equipment, it is characterized in that: the print head of lattice type typing equipment is divided into n print point module from top to bottom along the font height direction, and carries out defect recovery work as follows:
(1) detects the lattice type typing equipment lettering and shortcoming whether occurs, if then start the defect recovery function;
(2), then mask those print point modules that the shortcoming situation occurs if started the defect recovery function;
(3) print set separately lettering content with other print point modules that shortcoming do not occur.
What (4) set out existing shortcoming is i print point module, the height of described i print point module is Hi, find from i nearest and impeccable j the print point module of print point module, if the total height of all print point modules is H between i print point module and j the print point module, print head and printing paper are done relative motion along the font height direction, the relative motion distance is (Hi+H), so that j print point module is positioned at original i residing operating position of print point module;
(5) replace i print point module printing note to need i the lettering content that the print point module is finished with corresponding print point in j the print point module;
(6) print head and printing paper are done rightabout relative motion along the font height direction, so that print head is got back to normal operation position;
(7) detect whether also to have other shortcomings, if having then return step (4); If no, then carrying out the lettering task of other normal flow handles.
The invention has the beneficial effects as follows: can strengthen the utility function of dot matrix typing equipment, make the user in being busy with one's work, need not to send the professional to keep in repair in machine, just can solve, be user-friendly to because of print head lacks the problem that pin causes print quality.
In addition, also can realize reasonable utilization, prolong the service life of print head, save use cost, have wide market application prospect print head.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
