Abstract
An image forming apparatus and a method of controlling power-saving modes of the image forming apparatus are provided. The method of controlling power-saving modes of the image forming apparatus includes beginning a first power-saving mode after standing by in a normal mode for first time if no print operation is implemented, and beginning a second power-saving mode after standing by in the normal mode for second standby time if an error occurs under implementation of a print operation, wherein the second time is shorter than the first time, and the second power-saving mode includes a an error-checking mode.
Claims33
A method of controlling power-saving modes of an image forming apparatus, the method comprising:
- beginning a first power-saving mode after standing by in a normal mode for first time if no print operation is implemented;
- and
- beginning a second power-saving mode after standing by in the normal mode for second time if an error occurs under implementation of a print operation, wherein the second time is shorter than the first time, and the second power-saving mode includes an error checking mode.
A method of controlling power-saving modes of an image forming apparatus, the method comprising:
- sequentially beginning a plurality of power-saving modes having different power-saving efficiencies starting from a lower power-saving efficiency after standing by in a normal mode for first time if a print operation is implemented;
- and
- sequentially beginning a plurality of power-saving modes having different power-saving efficiencies starting from a lower power-saving efficiency after standing by in the normal mode for second time if an error occurs under implementation of the print operation, wherein the second time is shorter than the first time, and the plurality of power-saving modes includes an error-checking mode.
A method of controlling power-saving modes of an image forming apparatus, the method comprising:
- sequentially beginning a plurality of power-saving modes having different power-saving efficiencies starting from a lower power-saving efficiency after standing by in a normal mode for first time if a print operation is implemented;
- and
- beginning a power-saving mode to switch the image forming apparatus to a state in which an error is checkable and information regarding the error is displayable after standing by in the normal mode for second time if the error occurs under implementation of the print operation, wherein the second time is shorter than the first time.
A method of controlling power-saving modes of an image forming apparatus, the method comprising:
- beginning a power-saving mode after standing by in a normal mode for first time if no print operation is implemented;
- and
- beginning another power-saving mode after standing by in the normal mode for second time if an error occurs under implementation of a print operation, wherein the second time is shorter than the first time.
An image forming apparatus comprising:
- an engine configured to form an image;
- a display unit;
- and
- a controller, wherein if the engine encounters an error, the controller switches the image forming apparatus to a state in which the error is checkable and information regarding the error is displayable when preset time has passed after occurrence of the error, and the controller controls the display unit to display information regarding the error.
