Embodiment approach

[0035] As another implementation manner, the above-mentioned printer also includes:

[0036] The paper jam error reporting module is used to set the paper jam fault flag and report an error when it is judged to be a paper jam. .

[0037] The printer paper jam detection method proposed by the present invention and the printer realize the function of printer paper jam error reporting, specifically: the printer prints a line of fonts, and then feeds the distance of one line of paper, reciprocating, and the platen will follow the printed paper. It moves and gradually falls until it falls and closes the paper collection limit switch. At this time, the corresponding paper collection program starts. The paper collection motor collects the printed paper through a certain transmission mode, and the paper platen shaft also follows it. After being raised to a certain level, the paper receiving limit switch is disconnected, and the printer starts to continue printing. It can be seen tha...

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 [0001] The invention relates to the technical field of printing, in particular to a printer jam detection method and a printer. Background technique [0002] At present, the structure of the printer is roughly composed of a printing motor drive module, a paper feed drive module, a paper delivery drive module, a detection module, a serial communication module, and a power supply module. When the printer is printing, every time a line of fonts is printed, the line spacing of one line is fed, and the action of collecting paper is carried out under the cooperation of printing and paper feeding, and it is also required that the rolled paper roll has a certain degree of tightening . [0003] The so-called printer paper jam means that the printer cannot print out the correct font normally due to the failure of the print head to feed the paper to be printed. Therefore, when the printer is jammed, the printer needs to stop printing and report a fault to the host co...
