The controller 60 may not only set a display mode corresponding to an operating state but also modify the display mode. For example, the controller 60 sets the operation state display unit 20 to emit red light for five seconds for an operating state where color mode, high speed mode and scan mode are performed at the same time according to selection by the user. In addition, the controller 60 sets the operation state display unit 20 to flicker blue light every three seconds for an operating state where monochrome mode, low speed mode and copy mode are performed at the same time.
Moreover, the controller 60 sets various display modes for an operating state which further includes operating modes such as a paper feeding state, fax mode, etc., and controls the operation state display unit 20 to display the display modes. The display mode setting may be done differently depending on an operating state which includes various operating modes and changed according to selection by the user. Thus, the user may easily recognize the operating state through the display mode, and the operating state may be set and modified variously by the user.
FIG. 5 illustrates a control method of the image forming apparatus which has the following configuration.
In FIG. 5, a selection is input to the controller 60 through the user input unit 40 to select a display mode corresponding to an operating state which includes at least one operating mode of a plurality of operating modes (operation S10). Here, the controller 60 may receive an operating state and information on a display mode corresponding to the operating state from the host apparatus 200 through the communication unit 50. Otherwise, the information on the display mode may be preset when the image forming apparatus is manufactured.
At this point, the storage unit 30 stores the display mode input at operation S10 which corresponds to the operating state which includes at least one operating mode of the operating modes (operation S20).
In FIG. 5, the controller 60 displays a display mode corresponding to an operating state which is being performed if the image forming apparatus performs at least one operating mode of the operating modes (operation S30). Here, a display mode corresponds to the display mode associated with the operating state selected at operation (operation S20). Then, the controller 60 may modify the set display mode according to selection by the user.
As described above, an image forming apparatus according to embodiments of the present general inventive concept displays an operating state in various display modes so that a user may easily recognize various operating modes.
In particular, a user may set and modify the display mode corresponding to various operating modes.
