  • Publication number: 20190070876
    Abstract: The present invention relates to a paper jam sensing and recovery method for a receipt printer, the method enabling accurate measuring and determining of a motor overload state, which is most problematic when jam occurs, and enabling an immediate response if an overcurrent is generated on the basis of a driving current, such that damage to the motor or a driving circuit is fundamentally prevented and, also, paper jam occurring in a peripheral part of a printer cutter can be prevented in advance, thereby blocking product damage.
