Abstract:
1. A pickup error-sensing apparatus for an image forming apparatus, comprising: a sensing actuator positioned on a paper cassette and movable when sheets of paper are loaded into the paper cassette; a paper sensor unit outputting a paper loading signal and a paper unloading signal according to the movement of the sensing actuator; a sensing actuator-operating unit moving the sensing actuator to a first position where the paper sensor outputs the paper unloading signal when a pickup unit carries out a pickup movement, and moving the sensing actuator to a second position where the paper sensor unit outputs the paper loading signal after and before the pickup movement of the pickup unit; and a control unit determining whether the paper unloading signal is output from the paper sensor unit when the pickup unit carries out the pickup movement, and determining an occurrence of a pickup error when the paper loading signal is not output, and interrupting the operation of the image forming apparatus when the occurrence of the pickup error is determined.
