Upon accepting a remote support start instruction from a user via the start screen, the image forming apparatus obtains identification information from the relay server and displays the obtained identification information. Upon accepting an operator operation, the information processing apparatus accepts the identification information, connects to the image forming apparatus using the accepted identification information, and activates a remote support client application. Even upon reception of press information of a specific key from the information processing apparatus, the image forming apparatus can display the remote support screen in preference to the display of the operation screen. ## Claims ### Claim 1 An information processing system including an image forming apparatus, an information processing apparatus, and a relay server, the image forming apparatus including: a first memory device that stores a set of instructions; and at least one first processor that executes the instructions in the first memory device to: upon accepting a first operation of performing a predetermined operation for a hardware key provided in the image forming apparatus, display preferentially, on an operation unit and instead of a displayed normal screen on which operation is restricted due to occurrence of an error, a remote support start screen, wherein the remote support start screen including a start button for performing a remote support start instruction; and upon accepting the remote support start instruction by a user operating the start button, control to obtain identification information for connecting the information processing apparatus from the relay server and display the obtained identification information on the operation unit, and the information processing apparatus including: a second memory device that stores a set of instructions; and at least one second processor that executes the instructions in the second memory device to: accept the identification information by accepting an operation of an operator who uses the information processing apparatus; connect to the image forming apparatus via the relay server using the accepted identification information; and upon connecting to the image forming apparatus, activate a client application of the remote support to start the remote support. ### Claim 2 (depends on 1) The system according to claim 1, wherein the at least one second processor executes the instructions in the second memory device to: upon accepting a second operation of causing the operator to press keys in a specific order via a screen of the client application, transmit the press information of the specific key to the image forming apparatus; and wherein the at least one first processor executes the instructions in the first memory device to: upon reception of the press information of the specific key from the information processing apparatus, display a remote support screen associated with the remote support preferentially on the operation unit. ### Claim 3 (depends on 2) The system according to claim 2, wherein the at least one second processor executes the instructions in the second memory device to: upon accepting a third operation of causing an operator to press a predetermined button provided in a screen different from the screen of the client application, automatically transmit the press information of the specific key to the image forming apparatus, and transmit image data to the image forming apparatus via the client application. ### Claim 4 (depends on 2) The system according to claim 2, wherein the at least one second processor executes the instructions in the second memory device to: upon accepting a fourth operation of causing an operator to perform an end instruction for ending the remote support, automatically transmit the press information of the specific key to the image forming apparatus. ### Claim 5 (depends on 3) The system according to claim 3, wherein the at least one second processor executes the instructions in the second memory device to: in automatically transmitting the press information of the specific key to the image forming apparatus, if the client application is not activated, activate the client application. ### Claim 6 (depends on 5) The system according to claim 5, wherein the at least one second processor executes the instructions in the second memory device to: in automatically transmitting the press information of the specific key to the image forming apparatus, if the client application is activated, end the client application upon completion of transmission. ### Claim 7 (depends on 1) The system according to claim 1, wherein the first operation is one of a long press of the hardware key, and a simultaneous press of a plurality of hardware keys. ### Claim 8 An image forming apparatus communicable with an information processing apparatus via a relay server, comprising: a memory device that stores a set of instructions; and at least one first processor that executes the instructions to: upon accepting a first operation of performing a predetermined operation for a hardware key provided in the image forming apparatus, display preferentially, on an operation unit and instead of a displayed normal screen on which operation is restricted due to occurrence of an error, a remote support start screen, wherein the remote support start screen including a start button for performing a remote support start instruction; and upon accepting the remote support start instruction by a user operating the start button, control to obtain identification information for connecting the information processing apparatus from the relay server and display the obtained identification information on the operation unit. ### Claim 9 A control method of an information processing system including an image forming apparatus, an information processing apparatus, and a relay server, the method comprising: in the image forming apparatus, upon accepting a first operation of performing a predetermined operation for a hardware key provided in the image forming apparatus, displaying preferentially, on an operation unit and instead of a displayed normal screen on which operation is restricted due to occurrence of an error, a remote support start screen, wherein the remote support start screen including a start button for performing a remote support start instruction; and upon accepting a remote support start instruction by a user operating the start button, obtaining identification information for connecting the information processing apparatus from the relay server and displaying the obtained identification information on the operation unit, and in the information processing apparatus, accepting the identification information by accepting an operation of an operator who uses the information processing apparatus; connecting to the image forming apparatus via the relay server using the accepted identification information; and upon connecting to the image forming apparatus, activating a client application of the remote support to start the remote support. ### Claim 10 A control method of an image forming apparatus communicable with an information processing apparatus via a relay server, the method comprising: upon accepting a first operation of performing a predetermined operation for a hardware key provided in the image forming apparatus, displaying preferentially, on an operation unit and instead of a displayed normal screen on which operation is restricted due to occurrence of an error, a remote support start screen, wherein the remote support start screen including a start button for performing a remote support start instruction; and upon accepting the remote support start instruction by a user operating the start button, obtaining identification information for connecting the information processing apparatus from the relay server and displaying the obtained identification information on the operation unit. ### Claim 11 A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute each step of a control method of an image forming apparatus communicable with an information processing apparatus via a relay server, the control method comprising: upon accepting a first operation of performing a predetermined operation for a hardware key provided in the image forming apparatus, displaying preferentially, on an operation unit and instead of a displayed normal screen on which operation is restricted due to occurrence of an error, a remote support start screen, wherein the remote support start screen including a start button for performing a remote support start instruction; and upon accepting a remote support start instruction by a user operating the start button, obtaining identification information for connecting the information processing apparatus from the relay server and displaying the obtained identification information on the operation unit.
