MULTI-FUNCTION ACTUATOR OF PRINTER FOR BOTH-SIDED PRINTING

摘要

PURPOSE: A multi-function actuator of a printer for both-sided printing is provided to separate a pressing roller from a heating roller when an actuator separator is operated to remove a jam. CONSTITUTION: A multi-function actuator of a printer includes a guide duplex(101), a jam removal unit(125), and a sensor arm(106). The guide duplex is rotatively set on a pressing roller and installed in a printer frame and a heating roller and has a hollow. A plurality of guide pins having a bar shape are formed on the outer face of the guide duplex. The jam removal unit penetrates the hollow of the guide duplex to rotate and separates the pressing roller from the heating roller when it removes jammed paper from the heating roller. The sensor arm operates a sensor set in the frame when the guide duplex is rotated. The bottom of the sensor arm is supported by a support end of the guide duplex.
