Disclosed are a self-driving multifunction copier capable of performing artificial intelligence learning through machine learning, a server controlling the self-driving multifunction copier, and a method for operating the server. A method for operating a server controlling a self-driving multifunction copier in an Internet of things (IoT) environment constructed through a 5G communication network, which is a method for operating a server controlling a self-driving multifunction copier, includes: in response to receiving an execution request for a job from a user terminal in a building, calculating a processing time of the job; selecting one self-driving multifunction copier among a plurality of self-driving multifunction copiers in the building based on the processing time of the job; and assigning the job to the selected self-driving multifunction copier to allow the selected self-driving multifunction copier to perform the assigned job.
