Abstract
A printing device for printing tickets in public places, with an anti-paper jam system in which an optical sensor for detecting the presence of paper is arranged at a zone where a rise of the paper occurs in case of occlusion of the paper outlet mouth; before the start of a print, the paper is retracted with respect to the sensor, whereby the sensor is OFF; when the print starts, the paper advances until arriving in front of the sensor, whereby the sensor turns ON; from this moment on, if the to sensor returns OFF, it means that the paper is no longer detected by the sensor, because it has been raised by an occlusion, whereby the advancing of the paper is interrupted.
Claims11
A printing device comprising:
- a path for supplying a paper towards an outlet of a printed document;
- a print head for printing on the paper that advances along said path;
- an alteration in said path for promoting a rise of the paper if the normal advancing of the paper is obstructed;
- a sensor arranged along said path for detecting non-raised paper on said path;
- a controller for interrupting said print head if said sensor no longer detects paper along said path.
A method for controlling a printing device comprising the steps of:
- starting the print of a document only if a paper sensor does not detect the presence of paper;
- continuing the print of the document until said sensor detects the presence of paper;
- after said detection, continuing the print of the document if said sensor detects the presence of paper and interrupting the print if said sensor no longer detects the presence of paper;
- after an interruption, resuming the print of the same document if said sensor returns to detect the presence of paper.
