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.

Claim (Index 2):
The method of  claim 1 , wherein operation (S2) of determining the jam occurrence situation further comprises:\n operation (S2b) of starting to drive the cutter driving motor  150  in a forward direction when recognizing the output command (S2a); detecting a driving current applied to the cutter driving motor  150  through the current sensing unit  140 , and then determining whether the driving current exceeds a preset reference current value (S2c); if the drive current is determined to exceed the reference current value, operating a brake on the drive of the cutter driving motor  150  (S2d), and then operation (S2e) of driving the cutter driving motor  150  in a reverse direction until the cutter position sensor  160  senses a current return; and operation of (S2f) of transmitting a jam occurrence situation signal.
