Abstract
The embodiment of the invention discloses a printer and a paper jam detection method of the printer. A paper-collecting mini-type limiting switch of the existing printer is taken as a paper jam detection component, and integrated with software and compatible with the paper collecting function of the original paper-collecting limiting switch to timely detect the paper jam of the printer, so that the paper jam fault can be timely shot, and the safety of print data can be guaranteed; and the solution is simple, and no additional detection circuit is added.
Description
Technical field
The present invention relates to the printing technique field, relate in particular to a kind of printer paper jam detection method and printer.
Background technology
At present, the structure of printer is roughly formed by printing motor drive module, paper feed driver module, collection driver module, detection module, serial communication modular and power module etc.Printer when print job, every printing delegation font, with regard to the line-spacing of paper feed delegation, and the action of collection is to print, carrying out under the action that paper feed is worked in coordination, the paper roll that also requires to accept has certain degree of tightening up.
So-called printer paper jam is meant treats that printing paper is owing to printhead can't make printer normal printing go out correct font by paper feed.Therefore, just need printer to stop to print during the printer paper jam and the newspaper fault is given host computer, make this fault in time to get rid of, do not lost with the data of printing with the protection user.But prior art can't detect by the printer paper jam, causes fault in time to get rid of, and causes losing of print data.
Summary of the invention
Embodiment of the invention technical problem to be solved is, a kind of printer paper jam detection method and printer are provided, and detects to realize the printer paper jam under the prerequisite that does not increase additional detection circuits.
In order to solve the problems of the technologies described above, the embodiment of the invention has proposed a kind of printer paper jam detection method, and this method is based on the printer with collection limit switch, and said method comprises:
Obtain data to be printed from buffer area;
Paper feed distance when said data are printed and write down printing;
Whether when said paper feed presets threshold value apart from arrival, it is closed to detect said collection limit switch,
If not, then be judged as paper jam.
Correspondingly, the embodiment of the invention also provides a kind of printer, comprising:
Serial communication modular is used for obtaining data to be printed from buffer area;
The paper feed driver module is used to drive the paper feed action of paper;
Print motor drive module; Be used for said data are printed;
Drive the collection driver module that carries out the collection action by the collection limit switch;
Detection module is used for the paper feed distance when record was printed when said data were printed, and when said paper feed presetted threshold value apart from arrival, whether closed, if not, then be judged as paper jam if detecting said collection limit switch.
The beneficial effect of the embodiment of the invention is:
Through utilizing the paper jam detection means of the existing collection margin microswich of printer as printer; Collection measuring ability in conjunction with software and compatible former collection limit switch; The printer paper jam in time detects, thereby can in time get rid of the paper jam fault, guarantees the safety of print data; Solution is simple, need not to increase extra testing circuit.
Description of drawings
Fig. 1 is the flow chart of the printer paper jam detection method of the embodiment of the invention.
Fig. 2 is the structure chart of the printer of the embodiment of the invention.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can mutually combine, and below in conjunction with accompanying drawing and specific embodiment the present invention are done further explain.
The printer paper jam detection method of the embodiment of the invention is mainly based on the printer with collection limit switch, and as shown in Figure 1, this method comprises:
101, call the print command function;
102, obtain data to be printed from buffer area;
103, said data are printed and write down the paper feed distance when printing, the line number of paper feed particularly, was then advanced the distance of delegation when this paper feed distance showed as data are printed when having printed delegation's word;
104, whether when said paper feed presets threshold value apart from arrival, it is closed to detect said collection limit switch; If not, carry out 105, if; Carry out 106; Particularly, preset the paper feed distance of indicated promptly being judged as of threshold value when paper jam takes place, this presets threshold value and sets according to parameters such as font size, font type, page setups;
105, be judged as paper jam, set paper jam fault flag stops to print and reporting an error;
106, the printing that is judged as paper jam not and proceeds data is printed until said data and is finished;
107, withdraw from printing function.
Consult Fig. 2, the printer of the embodiment of the invention mainly comprises:
Serial communication modular 201 is used for obtaining data to be printed from buffer area;
Paper feed driver module 202 is used to drive the paper feed action of paper;
Print motor drive module 203; Be used for said data are printed;
Drive the collection driver module 204 that carries out the collection action by the collection limit switch;
As another kind of embodiment, above-mentioned printer also comprises:
The paper jam module that reports an error is used for when being judged as paper jam, and set paper jam fault flag also reports an error.。
Printer paper jam detection method and printer that the present invention proposes have been realized the function that the printer paper jam reports an error, particularly: the every printing of printer delegation font, the then distance of paper feed delegation; Reciprocation cycle, paper pressing shaft will be along with being fallen gradually by walking about of printing paper, up to falling collection limit switch closure; The program start of corresponding collection is just arranged this moment; The collection motor will be accepted by printing paper through certain kind of drive, and paper pressing shaft also is elevated thereupon, rise to a certain degree after; The collection limit switch breaks off, and printer just begins to continue to print.It is thus clear that after the every printing several rows of the printer font, paper pressing shaft will fall to the collection margin microswich, makes its closure, this is the cyclic process that printer can normal printing.When paper jam appears in printer, treat that then printing paper can't get into printhead, also just can't in printhead, be come out by printing paper, paper pressing shaft just can not fall, and the collection limit switch just can be not closed yet.Thereby utilize the collection limit switch after printing several rows, can closed can be used as to judge the whether foundation of paper jam of printer.On software is realized, only need in the program of paper feed delegation, the paper feed line number to be counted,, just can judge printer paper jam does not take place if several rows collection margin microswich is closed; Otherwise; Just be judged as the printer paper jam, at this moment, printer should stop to print and reporting an error.
Although illustrated and described embodiments of the invention; For those of ordinary skill in the art; Be appreciated that under the situation that does not break away from principle of the present invention and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited accompanying claims and equivalency range thereof.
