Image forming apparatus that changes to an image-formation ready mode from a power-save mode based on a frequency of use of the image forming apparatus by an external device

摘要

An image forming apparatus is provided. The apparatus includes an image forming unit which performs an image forming job, a communication unit which forms a wireless network according to a predetermined wireless communication standard, a control unit which, if at least one terminal device is connected to the communication unit through the wireless network, determines whether it is required to perform warming-up of the image forming apparatus and performs warming-up of the image forming apparatus, and a storage unit which stores information regarding a connection status of the terminal device. Accordingly, stand-by time for performing an image forming job may be reduced.

主权项

1. An image forming apparatus, comprising: a connection unit to establish a communication connection with an external device; a condition analysis unit to determine whether a predetermined condition exists corresponding to a high likelihood that the image forming apparatus will receive an image forming request from the external device; and
a controller to control the image forming apparatus to change from a power-save mode to an image-formation ready mode when it is determined that the predetermined condition exists and based on a comparison of unique information of the external device with pre-stored unique information, wherein the predetermined condition includes a case in which a frequency of use exceeds a threshold value, wherein the frequency of use is a ratio of a number of times an image forming job is performed based on the request by the external device connected with the image forming apparatus to a number of times the external device is connected with the image forming apparatus.
