Information processing apparatus, method, and non-transitory recording medium

A method executed by an operation panel communicably connected with a controller of an image forming apparatus, the operation panel and the image forming apparatus being configured to activate separately, the method including:

• in a case the controller completes an activation after the operation panel completes an activation, detecting a connection error between the operation panel and the controller by performing a first determination process of determining whether activation of the controller is completed within a first predetermined period of time after activation of the operation panel is completed and by performing a second determination process of determining whether communication between the operation panel and the controller is established within a second predetermined period of time after completion of the activation of the controller;
• and
• in a case the controller completes the activation before the operation panel completes the activation, detecting the connection error between the operation panel and the controller by performing the second determination process.

A non-transitory recording medium which, when executed by one or more processors on an operation panel communicably connected with a controller of an image forming apparatus, the operation panel and the controller being configured to activate separately, cause the processors to perform a method including:

• in a case the controller completes an activation after the operation panel completes an activation, detecting a connection error between the operation panel and the controller by performing a first determination process of determining whether activation of the controller is completed within a first predetermined period of time after activation of the operation panel is completed and by performing a second determination process of determining whether communication between the operation panel and the controller is established within a second predetermined period of time after completion of the activation of the controller;
• and
• in a case the controller completes the activation before the operation panel completes the activation, detecting the connection error between the operation panel and the controller by performing the second determination process.
