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 1):
A method of detecting and recovering a paper jam of a receipt printer that outputs a receipt according to an output control signal of a main system  10 , the method comprising:\n operation (S1) of performing a printer output command in a printer control unit  100  according to an output command S0 of the main system  10 ; operation (S2) of detecting a drive current applied to a cutter driving motor  150  through a current sensing unit  140  and then, determining a jam occurrence situation if a predetermined current value is exceeded; operation (S4) of transmitting a jam occurrence situation signal to the main system  10  when it is determined as the jam occurrence situation; checking whether or not the jam occurrence situation is restored (S5), and performing operation (S5a) of transmitting a jam occurrence situation restoration completion signal to the main system  10  if it is confirmed that the jam occurrence situation is restored; if the main system  10  receives the jam occurrence situation signal, waiting until the jam occurrence situation recovery completion signal is received (S6), and if the jam occurrence situation recovery completion signal is received, operation (S6) of performing operation (S1) of performing the printer output command in the printer control unit  100  again; and if the output is completed according to the printer output command (S3), operation (S3a) of outputting a normal output completion signal to the main system  10 .
