In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

A method of processing commands from a controller of an image forming device by a chip on supply item in the image forming device is described. A toner container installable in an image forming device having a controller according to one example embodiment includes a housing having a reservoir for storing toner. A chip is positioned on the housing and configured to receive a first write command from the controller of the image forming device. The chip is further configured to determine whether a transmission cycle bit of the first write command matches a transmission cycle bit of a second write command received by the chip from the controller of the image forming device previous to the first write command. The chip is further configured to resend to the controller of the image forming device a response to the second write command if the transmission cycle bit of the first write command matches the transmission cycle bit of the second write command.

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 forming apparatus includes: an image former that forms a correction patch using toner; a measurer that measures a color, a density, or a deposited amount of toner of the correction patch; and a hardware processor that calculates a reference correction amount on the basis of a measurement value of the measurer so that the density of the correction patch reaches a target value, and corrects an image forming condition of the image former by a first correction amount smaller than the reference correction amount.

An image forming apparatus includes a developing device, an image bearing member, an image density detecting portion, a toner content detecting portion, a humidity sensor, a supplying portion, and a controller configured to control the supplying portion so that a toner content is between an upper limit and a lower limit thereof. The controller can execute setting control in which the target value of the toner content is set on the basis of an image density of a reference toner image. The controller sets the lower limit until execution of subsequent setting control, wherein the lower limit is higher when a humidity is a first humidity and an average image ratio is a first ratio than when the humidity is a second humidity higher than the first humidity and the average image ratio is a second ratio larger than the first ratio.

To make it possible to apply optimal decoding processing to an encoded stream including a plurality of pieces of encoded data having degree-of-priority information. An encoded stream including a plurality of pieces of encoded data having degree-of-priority information is acquired. Whether or not a decoding ability of a reception side is equal to or greater than a decoding ability of the own side is determined on the basis of decoding ability information of the reception side indicating to what number of degree of priority decoding can be performed. In a case where the decoding ability of the reception side is equal to or greater than the decoding ability of the own side, an encoded stream is transmitted. On the contrary, in a case where the decoding ability of the reception side is less than the decoding ability of the own side, a decoded stream including decoded data generated by subjecting the encoded stream to decoding processing is transmitted.

An information processing system includes an apparatus and a server system. The server system includes an apparatus information receiving unit, a content generation unit, a content information request receiving unit, a content information transmitting unit, a content request receiving unit, and a content transmitting unit. The apparatus information receiving unit receives apparatus information. The content generation unit generates a content based on the apparatus information. The content information request receiving unit receives a content information request from the apparatus. The content information transmitting unit transmits content information that can identify one or more contents generated by the content generation unit to the apparatus. The content request receiving unit receives a content request from the apparatus. The content transmitting unit transmits the content to the apparatus.

We disclose a method for printing by rotogravure, flexography, offset, inkjet or electrophotography invisible images that are viewable under UV light. The method generates juxtaposed dispersed dot halftones by first creating juxtaposed clustered dot halftones and by applying to them dispersed dot halftoning according to a blackness reduction factor. Dispersed dot halftoning is embodied by random threshold error diffusion. The resulting dispersed dot halftones comprise pixel segments located within the areas defined by the clustered dots. These pixel segments specify the areas of the cells to be engraved onto the rotogravure cylinder. For offset, they can be imaged onto an offset plate or for electrophotography, onto a photoconductor. The disclosed juxtaposed dispersed dot halftoning method can be embedded into a framework for the reproduction of fluorescent full color images with three or more invisible fluorescent inks. These invisible fluorescent color images offer a strong protection against counterfeits.
