An image-forming device and a method which can protect a paper feeder by intercepting a driving voltage supplied to the paper feeder and preventing a collision between constituent elements if the paper feeder is in an abnormal state. The image-forming device includes a loading unit in which printing papers are loaded, a motor to move the loading unit, a sensor module to detect a position of the loading unit and information about existence/non-existence of the printing papers in the loading unit, a motor control unit to move the printing papers to a predetermined feeding position by driving the motor if a feeding command is received, a driving voltage supply unit to supply a driving voltage required for driving the motor to the motor control unit, and a switch to intercept a transfer of the driving voltage to the motor control unit if the loading unit moves over a predetermined range of position and becomes in contact with the switch.
