A system is disclosed. The system at least one physical memory device to store ink estimation logic and one or more processors coupled with the at least one physical memory device, to execute the ink estimation logic to receive a histogram for each of a plurality of color planes, receive uncalibrated ink deposition data for a printing system, perform a direct conversion of the uncalibrated ink deposition data to generate first calibrated ink deposition data and generate estimated ink usage data for each of the plurality of color planes based on the histograms and the first calibrated ink deposition data.

According to one embodiment, an image forming apparatus includes a printer unit that includes a driving member related to the supply of the developer, a storage unit that stores correction information regarding the correction of a supplied amount of the developer and a remaining amount of the developer, and a control unit. The control unit acquires driving information regarding the driving of the driving member. The control unit acquires the correction information in accordance with the remaining amount of the developer and estimates the remaining amount of developer based on the driving information and the correction information when the remaining amount of the developer stored in the storage unit satisfies a predetermined condition regarding the remaining amount, and estimates the remaining amount of the developer based on the driving information when the remaining amount of the developer stored in the storage unit does not satisfy the predetermined condition.

An image processing apparatus includes a printing unit configured to print an image on a sheet, a first sensor configured to detect a document in a reading unit, a second sensor configured to detect an error related to printing of the image by the printing unit, and a controller configured to generate a first screen for display presenting functions that can be executed by the image processing apparatus. The controller is further configured to, when the first sensor detects the document and the second sensor detects the error, generate a second screen for display indicating one or more first functions that require the reading unit but are not related to the printing of the image by the printing unit.

An information processing device may notify first notification information in a case where a remaining amount of colorant in a first-type printer reaches a first remaining amount, notify second notification information in a case where the remaining amount reaches an unprintable remaining amount, notify third notification information in a case where a remaining amount of colorant in a second-type printer reaches a second remaining amount, and notify fourth notification information in a case where the remaining amount reaches the unprintable remaining amount. The first-type printer may include a tank for storing colorant supplied from a first cartridge to a first print executing unit. The first remaining amount may be a remaining amount in a state where the colorant does not remain in the first cartridge but remains in the tank. The second-type printer may include a second print executing unit and may not include a tank.

A consumables management system includes a plurality of printers in each of which a consumables container is installed and each of which is configured to consume consumables contained in the consumables container, and a management unit connected via a network to the plurality of printers. The management unit manages container identification information assigned to the consumables container, device identification information assigned to each of the plurality of printers, and user identification information assigned to the user of each of the plurality of printers in association with one another.

An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

Disclosed are a self-driving multifunction copier capable of performing artificial intelligence learning through machine learning, a server controlling the self-driving multifunction copier, and a method for operating the server. A method for operating a server controlling a self-driving multifunction copier in an Internet of things (IoT) environment constructed through a 5G communication network, which is a method for operating a server controlling a self-driving multifunction copier, includes: in response to receiving an execution request for a job from a user terminal in a building, calculating a processing time of the job; selecting one self-driving multifunction copier among a plurality of self-driving multifunction copiers in the building based on the processing time of the job; and assigning the job to the selected self-driving multifunction copier to allow the selected self-driving multifunction copier to perform the assigned job.

An image data processing method for estimating an ink consumption amount includes: an image data compression step of compressing image data after RIP processing by run-length encoding; and an ink consumption amount estimation step of calculating a predicted ink consumption amount when printing based on image data is performed by an inkjet printing device based on information on the number of occurrences for each gradation value obtained when run-length encoding is applied to image data and information on an ink consumption amount for each gradation value held in an ink consumption amount table prepared in advance.

An advertisement system includes a distribution member computer that causes a printer to print the test image data received from a posting server and transmits read data obtained by reading an image of a printed matter obtained by printing test image data by the printer to a posting server, and the posting server including an evaluation unit that evaluates printing quality of the printed matter based on the read data and a decision unit that determines whether to distribute the advertisement data to the distribution member computer based on an evaluation result by the evaluation unit.

An information processing device may notify first notification information in a case where a remaining amount of colorant in a first-type printer reaches a first remaining amount, notify second notification information in a case where the remaining amount reaches an unprintable remaining amount, notify third notification information in a case where a remaining amount of colorant in a second-type printer reaches a second remaining amount, and notify fourth notification information in a case where the remaining amount reaches the unprintable remaining amount. The first-type printer may include a tank for storing colorant supplied from a first cartridge to a first print executing unit. The first remaining amount may be a remaining amount in a state where the colorant does not remain in the first cartridge but remains in the tank. The second-type printer may include a second print executing unit and may not include a tank.
