Abstract

An image forming apparatus includes an image forming unit, an execution unit that executes dew condensation elimination operation for eliminating dew condensation in the image forming unit, a setting unit that sets a dew condensation prevention mode for executing the dew condensation elimination operation to an enabled state, a display unit, and a control unit that causes the display unit to display a warning screen and selects a type of image forming job to be restricted during execution of the dew condensation elimination operation in a case where the dew condensation prevention mode is set to an enabled state, wherein, in a case where an image forming job is received during execution of the dew condensation elimination operation, the control unit determines whether the received image forming job is executable based on the type of job selected.

First claim

What is claimed is:

1 . An image forming apparatus comprising:
an image forming unit configured to form an image on a sheet; an execution unit configured to execute dew condensation elimination operation for eliminating dew condensation occurring in the image forming unit; a setting unit configured to set a dew condensation prevention mode for executing the dew condensation elimination operation to an enabled state; a display unit configured to display information; and a control unit configured to cause the display unit to display a warning screen and to select, based on a user instruction, a type of image forming job to be restricted during execution of the dew condensation elimination operation in a case where the dew condensation prevention mode is set to an enabled state, wherein, in a case where an image forming job is received during execution of the dew condensation elimination operation, the control unit determines whether the received image forming job is executable based on the selected type of image forming job.

2 . The image forming apparatus according to claim 1 , wherein the warning screen displays information indicating a possibility of a quality of a printed material being lowered during execution of the dew condensation elimination operation.

3 . The image forming apparatus according to claim 1 , wherein the control unit enables a user to select a type of image forming job to be restricted during execution of the dew condensation elimination operation after causing the display unit to display the warning screen.

4 . The image forming apparatus according to claim 1 , wherein the image forming job includes one or more of a facsimile job for executing image forming operation based on facsimile data, a print job for executing image forming operation based on print data, and a copy job for executing image forming operation based on image data acquired from a document reading unit.

5 . The image forming apparatus according to claim 1 , wherein execution of a facsimile job received during execution of the dew condensation elimination operation is prohibited while execution of an image forming job other than the facsimile job is permitted based on the selected type of job.

6 . The image forming apparatus according to claim 1 , wherein execution of all image forming jobs received during execution of the dew condensation elimination operation is prohibited based on the selected type of job.

7 . The image forming apparatus according to claim 1 , wherein a facsimile job received during execution of the dew condensation elimination operation is changed to a job to be received in a memory based on the selected type of job.

8 . The image forming apparatus according to claim 1 , wherein the warning screen is displayed in a case where an image forming job is received.

9 . The image forming apparatus according to claim 1 , wherein the execution unit executes the dew condensation elimination operation in a case where dew condensation is detected in the image forming unit.

10 . The image forming apparatus according to claim 1 , wherein the execution unit executes the dew condensation elimination operation based on a setting instruction of the dew condensation prevention mode.

11 . The image forming apparatus according to claim 1 , wherein the execution unit executes the dew condensation elimination operation by rotationally driving a fan for sending air to the image forming unit.
