A method for controlling paper feeding is performed in an image forming apparatus having a feeding sensor for sensing paper feeding states and for generating a sensing signal that sequentially shifts between first and second states during the paper feeding. The method contemplates the steps of picking up and feeding a sheet of paper in response to a printing command; determining whether a predetermined time period has elapsed since the sheet of paper was picked up; after the predetermined time period has elapsed, detecting when the sensing signal shifts to the first state; after the sensing signal shifts to the first state, detecting when the sensing signal shifts to the second state; after the sensing signal shifts to the second state, starting a counting operation and detecting when the sensing signal shifts back to the first state; after the sensing signal shifts back to the first state, comparing a present counting value generated from the counting operation with a reference value; when the present counting value is less than the reference value, returning to the step of detecting when the sensing signal shifts to the second state; and when the present counting value is greater than or equal to the reference value, performing a normal image forming operation. |
