An information processing apparatus is communicably connected to an image forming apparatus and acquires a consumption amount of a consumable in the image forming apparatus, outputs a delivery request for a replacement consumable based on the acquired consumption amount, and notifies information for prompting to stock a spare replacement consumable based on the consumption amount.

Information processing apparatus, method of controlling information processing apparatus, and image forming apparatus

An image forming apparatus which forms an image by using toner from a toner container mounted thereto. Consumption data is acquired, related to a toner consumption amount of the image forming apparatus, and based on the consumption data there is a determination of the number of remaining days until a predicted date in which a replacement of the toner container mounted onto the image forming apparatus is predicted. The number of the remaining days is displayed; however, the number of the remaining days is not displayed until a condition is satisfied related to the number of sheets on which images are formed by the image forming apparatus, wherein the condition is satisfied in a case where the number of sheets on which images are formed by the image forming apparatus is more than a predetermined number of sheets.

Information processing apparatus and control method for an image forming apparatus

An information processing apparatus communicating with an image forming apparatus on which toner containers containing toners of different colors are mounted and which forms an image using the toners of different colors includes an acquisition unit configured to acquire, for each color, a stock request of a toner container to be stocked being different from the toner containers mounted on the image forming apparatus, and a display unit configured to display, for each color, stock information indicating that stocking of a spare toner container is required, in accordance with the stock request acquired by the acquisition unit.

An image forming apparatus including a consumable to be used for image formation. The image forming apparatus includes: a usage amount detector configured to detect a cumulative value of a usage amount of the consumable and a remaining amount of the consumable; a predictor configured to predict a period that allows use of the consumable based on the remaining amount detected by the usage amount detector; and a determination unit configured to generate a delivery request signal for prompting a delivery request for the consumable when the period that allows the use predicted by the predictor is smaller than a predetermined number-of-day threshold value. The image forming apparatus avoids performing processing for generating a delivery request signal by the determination unit after the start of the use of the image forming apparatus until a predetermined condition is satisfied.

An information processing apparatus is different from an image forming apparatus, with the image forming apparatus forming an image by using toner supplied from a toner container mounted on the image forming apparatus. The information processing apparatus includes a communication unit to communicate with the image forming apparatus, an acquisition unit to acquire, via the communication unit, a remaining day count until a date which is expected as a date that the toner container mounted on the image forming apparatus is replaced, and acquire, via the communication unit, a stock request signal for stock request of a toner container for stocking different from the toner container mounted on the image forming apparatus, and a display to display stock information relating to the toner container for stocking based on the stock request signal, and display the remaining day count.
