A depinching mechanism including a frame, a star wheel assembly, a limiter arm, a rocker arm and a sensor is provided in present invention. Through the depinching mechanism the star wheel assembly is lifted from the first position to the second position when paper jam occurs, and thus depinched the media the user can clear the paper jam. And after that the star wheel assembly is lowered from the second position to the first position. The star wheel assembly remains in the first position in the normal printing process. Since when paper jam occurs the star wheel assembly is lifted by the depinching mechanism, the user can easily and conveniently remove the jammed paper. And thus, the depinching mechanism can facilitate the user to remove jammed paper when paper jam occurs in printer. Thus, the depinching mechanism can be used in printers to solve the paper jamming problems.

Depinching mechanism for paper jam removal in printer

A depinching mechanism including a frame, a star wheel assembly, a transmitting device and a sensor is provided in present invention. Through the transmitting device rotating reversely, the star wheel assembly is lifted to the second position when paper jam occurs, thus depinched the media so that user can clear the paper jam. After that the star wheel assembly is lowered to the first position again. The star wheel assembly remains in the first position in normal printing process. Using a one-way clutch and a cam with an outer predetermined profile, the transmitting device rotates forwardly without transmitting any torque during normal printing process, and rotates inversely with transmitting a torque to lift the star wheel assembly up and lower the star wheel assembly down when paper jam occurs. Thus, the depinching mechanism can be used in printers to auto fix the paper jamming problems.
