Method and apparatus for performing maintenance in an image forming apparatus

A maintenance implementing method and apparatus of an image forming apparatus are provided to perform the optimum maintenance by correcting the position of the platen which operates along with the maintenance implementing unit. A maintenance implementing method of an image forming apparatus comprises a step of determining whether the correction of distance information is required(100), a step of detecting the actual separation distance between the initial position and the farthest position of the moving platen(102), a step of correcting distance information for the movement of platen by using the actual separation distance and the set separation distance(104), and a step of implementing maintenance operation, such as wiping, spitting, capping, and scraping, according to the corrected distance information.
