Image forming apparatus with history record display information and method of controlling image forming apparatus
It is assumed that a user changed a set value of paper selection, which is one of setting items of various setting items, from “auto” to “A3”. According to one embodiment, a controller extracts history records in which the set value of the paper selection is “A3” from setting information history in a storage, and arranges them to the side of the various setting items in chronological order. Specifically, the controller displays three pieces of setting information, starting with the latest setting information, followed by older setting information, on the right side of the various setting items. In displaying the pieces of setting information, in order to clarify and highlight parts having discrepancies relative to the set values of the various setting items, the color may be changed, a box may be used to surround such a part, or characters may be displayed in bold.
1. An image forming apparatus which performs job processing based on setting information, which is information on a set value of a setting item, the image forming apparatus comprising:
a display which displays a setting screen;
a storage which stores an initial set value of the setting item, and setting information history which is configured by accumulation of the past setting information; and
a controller which executes setting processing of determining the set value of the setting item, and the job processing, wherein
the controller extracts, each time the set value of the setting item is changed from the initial set value, at least one piece of setting information including the changed set value from the setting information history, and displays the extracted setting information as history record display information in such a way that the history record display information is selectable, and together with the present setting information, on the display.
2. The image forming apparatus according to claim 1 , wherein the controller displays the history record display information side by side in chronological order.
3. The image forming apparatus according to claim 1 , wherein the controller displays the history record display information side by side in descending order of a number of points of discrepancies relative to the present setting information.
4. The image forming apparatus according to claim 1 , wherein the controller displays the history record display information such that points of discrepancies relative to the present setting information.
5. The image forming apparatus according to claim 4 , wherein the controller displays the history record display information such that points of agreement with the present setting information.
6. The image forming apparatus according to claim 1 , wherein the controller displays the setting information having the points of discrepancies relative to the present setting information as the history record display information.
7. A method of controlling an image forming apparatus which performs job processing based on setting information, which is information on a set value of a setting item, the method comprising:
displaying a setting screen;
storing an initial set value of the setting item, and setting information history which is configured by accumulation of the past setting information; and
controlling of executing setting processing of determining the set value of the setting item, and the job processing, wherein
the controlling extracts, each time the set value of the setting item is changed from the initial set value, at least one piece of setting information including the changed set value from the setting information history, and displays the extracted setting information as history record display information in such a way that the history record display information is selectable, and together with the present setting information, in the displaying.
