In a method of controlling a digital inkjet printer, the digital printer is arranged to operate in a selected first print mode which includes a first speed in a main scanning direction. A digital image and a print setting that the digital image is planned to be printed in an enhanced adhesion print mode are received. A time period needed for a pass in the main scanning direction is extended by lowering a speed from the first speed to a second speed, and by enlarging the pass width up to a maximum medium width and/or by temporarily stopping the printer at an end of the pass. Marking material is ejected during the pass on the image receiving medium by a print head at the second speed within the extended time period, and is cured by a UV curing device at the second speed within the extended time period.

Described herein are bioprinters comprising: one or more printer heads, wherein a printer head comprises a means for receiving and holding at least one cartridge, and wherein said cartridge comprises contents selected from one or more of: bio-ink and support material; a means for calibrating the position of at least one cartridge; and a means for dispensing the contents of at least one cartridge. Further described herein are methods for fabricating a tissue construct, comprising: a computer module receiving input of a visual representation of a desired tissue construct; a computer module generating a series of commands, wherein the commands are based on the visual representation and are readable by a bioprinter; a computer module providing the series of commands to a bioprinter; and the bioprinter depositing bio-ink and support material according to the commands to form a construct with a defined geometry.

There is provided a controller for an image recording device. The image recording device includes: a carriage capable of moving in a first direction; a head mounted on the carriage and configured to discharge a liquid from a nozzle; and a wiper capable of being impregnated with a cleaning liquid, a nozzle surface of the head including a first region not having the nozzle and a second region having the nozzle. The controller is configured to execute: a pressing-against processing of abutting the wiper on the first region in a state in which a speed of a relative movement in the first direction between the carriage and the wiper is a first speed; and a moving processing of moving the carriage and the wiper relative to each other in the first direction at a second speed faster than the first speed, while abutting the wiper on the second region.

A motor of a printer is capable of rotating at a rotation speed controlled to be constant based on a rotation position of a motor shaft measured by a motor encoder so as to move a carriage. A linear encoder measures positions of the carriage in a moving direction. Differences between each of rotation positions of the motor shaft based on the measurement by the motor encoder and a corresponding rotation position of the motor shaft based on the measurement by the linear encoder are calculated, for positions rotation during one or more rotation(s) of the motor shaft. A correction value to be added to the rotation positions of the motor shaft measured by the motor encoder is determined, based on the calculated differences, such that a change in the rotation speed of the motor shaft, during one rotation thereof, based on the measurement by the linear encoder, is decreased.

A liquid ejecting apparatus includes: a conveyer configured to convey a medium in a conveyance direction; a carriage configured to move in a reciprocating direction intersecting the conveyance direction at a position facing the medium conveyed in the conveyance direction; and a head provided on the carriage and including at least one nozzle configured to eject liquid to the medium, in which the head ejects the liquid in a continuous flow, converts the continuous flow into a plurality of droplets and causes the a plurality of droplets to collide with the medium.

In a state where a distance from an ejection port surface of an ejection head to a predetermined position corresponds to a first distance, a period detection unit detects a first period from when ejection of a droplet from an ejection port is started until when a droplet detection unit detects the droplet, and in a state where the distance from the ejection port surface of the ejection head to the predetermined position is changed to a second distance by a change unit, the period detection unit detects a second period from when ejection of a droplet from the ejection port is started until when the droplet detection unit detects the droplet, the second distance being different from the first distance. A calculation unit calculates an ejection speed of the droplet, based on the first distance, the second distance, the first period, and the second period.

An ink jet system includes a head unit that includes a nozzle discharging ink, a pressure chamber communicating with the nozzle, and a drive element applying pressure fluctuation to the ink in the pressure chamber by supplying a drive pulse, an acquisition portion that acquires output information including one or both of first output information regarding the head unit and second output information regarding the ink used for the head unit, a first coupling portion that is communicably network-coupled to a server, a first output portion that outputs the output information to the server via the first coupling portion, a first input portion to which input information is input from the server via the first coupling portion, and a determination portion that determines a drive timing of the drive element based on the input information.

An image forming system including: a head; a carriage moving mechanism including a carriage, a motor, and a transmission; a motor driver; an encoder; and a controller is provided. The controller is configured to: identify, regarding a certain period being each of the plurality of periods, an index value regarding abnormality of the image forming system based on time series data of a moving velocity, a physical amount related to the moving velocity, or an operation amount observed in a moving control of the carriage in the certain period; and determine an end of a service life of the image forming system or a remaining amount of the service life of the image forming system based on a change of the index value over the plurality of periods.

A method and system include controlling, by a control unit, a printer to form one or more tactile features on a surface of a component. Said controlling includes varying a speed of a print head of the printer to vary one or more attributes of the one or more tactile features. In at least one example, said varying the speed includes varying the speed of the print head of the printer during a single pass of the print head in relation to the surface of the component.
