If elements (curves) of a tone reproduction curve increase application of marking material, the magnitudes of the elements of the tone reproduction curve are summed. If the summed magnitudes of the elements of the tone reproduction curve exceed marking material limits, a warning message is output.

An information processing device may display a first remaining amount object having a first display manner in a case where a remaining amount of colorant in a first cartridge of a first-type printer comprising a tank is greater than zero, displays the first remaining amount object having a second display manner in a case where the remaining amount of colorant in the first cartridge is zero and a remaining amount of colorant in the tank is greater than an unprintable remaining amount, displays a second remaining amount object having a first display manner in a case where a remaining amount of colorant in a second cartridge of a second-type printer is greater than an unprintable remaining amount, and displays the second remaining amount object having a second display manner in a case where the remaining amount of colorant in the second cartridge is the unprintable remaining amount.

A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

A notification device capable of suppressing the occurrence of user's mistake in supplement of a printing liquid. An acquisition unit that acquires information relating to a residual amount of each of a plurality of printing liquids supplied to a printing apparatus and a determination unit that determines whether or not each of the plurality of printing liquids is a printing liquid of a notification target of which a residual amount is a predetermined amount or less based on the acquired information are included. In addition, a notification unit, in a case where a plurality of printing liquids of the notification target determined by the determination unit are present, notifies information relating to the residual amount of a predetermined printing liquid is included. This notification unit performs a notification with priority for a predetermined printing liquid satisfying a predetermined condition among the plurality of printing liquids of the notification target.

An electronic apparatus to which a removable device can be set is provided. The removable device includes a first memory to store first status information indicating a status of the removable device, first identification information identifying the removable device, and second identification information identifying the electronic apparatus. The electronic apparatus includes a second memory to store second status information indicating a status of the removable device that is set to the electronic apparatus, third identification information identifying the removable device set to the electronic apparatus, and fourth identification information identifying the electronic apparatus, and a processor to determine, when connected to the first memory of the removable device set to the electronic apparatus, whether the first identification information matches the third identification information and the second identification information matches the fourth identification information and update the second status information with the first status information based on a result of the determination.

A logic circuitry package for a replaceable print apparatus component includes an interface including a power terminal and at least one logic circuit. The at least one logic circuit is configured to respond to communications sent to a first address via the interface and respond to communications sent to a second address via the interface. The at least one logic circuit is configured to in response to a first command sent to the first address, draw a first current on the power terminal; and in response to a hibernate command sent to the first address, respond to communications sent to the second address and draw a second current on the power terminal less than the first current.

An example operation method of an image forming apparatus includes obtaining, through a sensor in the image forming apparatus, toner data corresponding to an amount of toner remaining in a developing apparatus, obtaining, based on the toner data in every predetermined period, a linear prediction model predicting the amount of toner remaining in the developing apparatus according to a time at which the toner is supplied to the developing apparatus, predicting, based on the linear prediction model, an expected supply time required for the amount of toner remaining in the developing apparatus to reach a target level, and controlling an operation of supplying the toner to the developing apparatus according to a result of comparing the expected supply time with a predetermined reference supply time.

An intelligent Print Device monitoring & manipulation method provided on a host computer that continually tracks in the connected/accessible print devices parameters like toner or ink cartridge/container along with identities & toner levels. As & when certain device statuses change, the invention will accordingly & progressively alter the density/resolution and such allied print device setting to achieve higher page yield from the available toner/ink present in cartridge. The alteration activity can be initiated automatically on-site &/or manually from remote location, when it is added as part of system platform that bridges client sites having print devices and the host computer to external service providers.

An information processing device according to aspects of the present disclosures configured to determine whether a managed device is a mobile device or a stationary device. When it is determined that the managed device is the mobile device, a first threshold value is set as a threshold value, and when it is determined that the managed device is the stationary device, a second threshold value is set as the threshold value. When it is determined that the remaining amount of the consumable is equal to or less than the threshold value, the information processing device issues a notification regarding the remaining amount of the consumable associated with the managed device. The notification is issued earlier in a case where the threshold value is the first threshold value than in a case where the threshold value the second threshold value.

A system for accurately managing the consumables of a network of printers. The system monitors the printers in the network, collects data relating to operation of the printers, determines the current state of the printers regarding at least one consumable, and uses the data and the current state of the printers to predict when at least one consumable of at least one printer of the network will need to be replaced.
