provide a notification of guidance for replacing the part if the event indicates an event to require replacement of the part; end the notification of the guidance using, as conditions, a case in which a state of a cover to be opened for the replacement of the part is set in a closed state and a case in which an input of a first instruction that the replacement of the part has completed is accepted; detect occurrence of another event related to another part of the image forming; apparatus; provide a notification of guidance for replacing the another part if the another event indicates an event to require replacement of the another part; detect a solution of the another event by replacement of the another part by using a component of the image forming apparatus, and end the notification of the guidance for replacing the another part when the solution of the another event is detected. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the part of the image forming apparatus is a part that the component of the image forming apparatus cannot detect a solution of the event to require replacement of the part. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the part is a photosensitive drum, a fixing unit, or an ADF maintenance kit. ### Claim 4 (depends on 1) The apparatus according to claim 1, further comprising a storage, and wherein the instructions further cause the image forming apparatus to store maintenance information of each of replaced parts of the image forming apparatus, and wherein the part is included in the replaced parts. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein the maintenance information includes at least one of a consumption degree of a part and an operation day count of a part, and the maintenance information of the part is reset when the input of the first instruction that the replacement of the part has completed is accepted. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein if the state of the cover changes from an open state to the closed state, a screen capable of accepting an input of the first instruction is provided, and if the input of the first instruction is accepted via the screen, the notification of the guidance is ended. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the instructions further cause the image forming apparatus to: accept a second instruction for providing a screen capable of accepting an input of the first instruction while a moving image related to the replacement of the part, and end the notification of the guidance using, as other conditions, a case in which the second instruction is accepted and a case in which an input of the first instruction is accepted via the screen provided based on the second instruction. ### Claim 8 (depends on 7) The apparatus according to claim 7, wherein the moving image includes a first moving image for setting the cover in an open state and a second moving image after the cover is set in the open state. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the notification of the guidance is provided in a status display region on a display of the image forming apparatus. ### Claim 10 A control method executed by an image forming apparatus, comprising: detecting occurrence of an event which related to a part of the image forming apparatus; providing a notification of guidance for replacing the part if the event indicates an event to require replacement of the part; ending the notification of the guidance using, as conditions, a case in which a state of a cover to be opened for the replacement of the part is set in a closed state and a case in which an input of a first instruction that the replacement of the part has completed is accepted; detecting occurrence of another event related to another part of the image forming; apparatus; providing a notification of guidance for replacing the another part if the another event indicates an event to require replacement of the another part; detecting a solution of the another event by replacement of the another part by using a component of the image forming apparatus, and ending the notification of the guidance for replacing the another part when the solution of the another event is detected. ### Claim 11 A non-transitory computer-readable storage medium storing a program for causing a computer to detect occurrence of an event which related to a part of the image forming apparatus; provide a notification of guidance for replacing the part if the event indicates an event to require replacement of the part; end the notification of the guidance using, as conditions, a case in which a state of a cover to be opened for the replacement of the part is set in a closed state and a case in which an input of a first instruction that the replacement of the part has completed is accepted; detect occurrence of another event related to another part of the image forming; apparatus; provide a notification of guidance for replacing the another part if the another event indicates an event to require replacement of the another part; detect a solution of the another event by replacement of the another part by using a component of the image forming apparatus, and end the notification of the guidance for replacing the another part when the solution of the another event is detected.
