发明名称 Pickup error-sensing apparatus of image forming apparatus and method therefor
摘要 A pickup error-sensing apparatus of an image forming apparatus and method therefor. The pickup error-sensing apparatus includes a sensing actuator rotatably disposed on a frame with respect to a paper cassette, displaceable when sheets of paper are loaded in the cassette, a paper sensor unit outputting a paper loading and unloading signals according to the displacement of the sensing actuator, a sensing actuator-operating unit operating the sensing actuator to allow the paper sensor unit to output the paper unloading signal when a pickup roller carries out a pickup movement, and a control unit determining whether the paper unloading signal is output when the pickup roller carries out the pickup movement, and determining occurrence of a pickup error to stop the image forming apparatus when the paper unloading signal is not output. The apparatus and method sense the pickup error generated from inadequate movement of the pick-up roller without installing a separate paper sensor.
