An information processing apparatus includes a sterilization unit that performs sterilization with an ultraviolet light source a part of the information processing apparatus that is operated on, a management unit that manages lifetime information corresponding to a product lifetime of the ultraviolet light source and usage information corresponding to an irradiation time and an irradiation output of the ultraviolet light source, and a control unit that controls the ultraviolet light source in a first control mode of controlling the ultraviolet light source with a first irradiation time and a first irradiation output or in a second control mode of controlling the ultraviolet light source with a second irradiation time shorter than the first irradiation time and a second irradiation output higher than the first irradiation output.

Information processing apparatus and method of controlling information processing apparatus

An information processing apparatus including at least one unit that receives a user operation, the information processing apparatus includes an ultraviolet irradiation device that performs disinfection processing for disinfecting at least a part of the at least one unit, an operation unit including a display that provides notification to a user, and a controller, wherein during the disinfection processing for the at least a part of the at least one unit, the controller causes the operation unit to provide notification to the user not to touch the information processing apparatus.

An image forming apparatus includes an operation unit for receiving an instruction given by a user, and according to receipt of a request of a print-and-delivery job from an external apparatus, performs print processing to produce a print and passes the produced print to a print delivery apparatus that delivers a print to a designated delivery destination. A controller controls an order of execution of jobs. In a state in which a print-and-delivery job has been registered in a job queue of the image forming apparatus, in a case where an instruction for executing a predetermined job which cannot be processed in parallel with the print-and-delivery job is received from the operation unit, the controller performs predetermined job priority control for causing the predetermined job to be preferentially executed.

Image forming apparatus that produces print for delivery, method of controlling image forming apparatus, and storage medium

An image forming apparatus performs printing based on a print job and receives a completion notification from an automatic printed material delivery apparatus. Based on receipt of the completion notification, the image forming apparatus transmits a receipt acknowledgement request to a personal computer (PC) corresponding to a user (a requested user or a designated user) based on the job. Further, the image forming apparatus receives, from the PC, an acknowledgement notification based on a user operation performed on the PC in connection with the receipt acknowledgement request. In response to receipt of the acknowledgement notification, the image forming apparatus registers information indicating that the printed material has been received by the user based on the job as a job log of the job.
