Abstract: In a transmission device with switchable gear ratios, a driving gear is disposed onto an output shaft of a motor, a rocker arm is pivoted on the output shaft through an electromagnetic clutch, a rocker arm gear mounted on the rocker arm is driven by the driving gear, a first gear set is driven by the rocker arm gear when the rocker arm is at a first position, a second gear set is driven by the rocker arm gear when the rocker arm is at a second position, and the first gear set and the second gear set have different output rotating speeds. In addition, a first magnetic element attracts the rocker arm at the first position, and a second magnetic element attracts the rocker arm at the second position. Thus, the gear ratio may be switched according to interactions between the electromagnetic clutch and the magnetic elements.

Abstract: A sheet feeder includes a separation roller, a friction roller, a shaft and an energy storing element. The energy storing element stores energy when the friction roller is driven by the separation roller to rotate in the sheet-feeding direction and releases energy to make the friction roller rotate in a direction opposite to the sheet-feeding direction.

Abstract: A fuser assembly of an electrophotographic printing device for fusing toners on a medium. The fuser assembly includes a fuser roller, a driving mechanism, a fuser substrate and a heating source. The driving mechanism connected to the fuser roller drives the fuser roller to rotate and thus the medium is moved by the fuser roller. The fuser substrate, being stationary and disposed opposite the fuser roller, is in sliding contact with the medium. The heating source heats the fuser substrate such that the fuser substrate fuses the toners on the medium.
