Abstract

A liquid-discharge-head driving device includes processing circuitry and a memory. The processing circuitry generates a drive signal based on voltage information on a voltage applied to a piezoelectric element of nozzles of a liquid discharge head and outputs the drive signal to the liquid discharge head, and acquires, based on droplet speed information acquired from a droplet speed measuring device that measures a discharge speed of a droplet discharged from the liquid discharge head and the voltage information, appropriate voltage information on a voltage at which the discharge speed falls within a predetermined range. The memory stores the appropriate voltage information in association with identification information of the nozzles and a drive frequency of the nozzles. The processing circuitry acquires, from the memory, the appropriate voltage information corresponding to the identification information and the drive frequency and outputs the drive signal based on the appropriate voltage information.

Abstract

A sheet processing apparatus includes a binder, a mover, and a posture changer. The binder binds a sheet bundle of multiple sheet media including a sheet medium conveyed to the binder in a conveyance direction. The mover moves the binder in an orthogonal direction orthogonal to the conveyance direction. The posture changer changes a posture of the binder that faces the sheet bundle, according to a change in a relative position between the posture changer and the binder in the orthogonal direction by a movement of the binder in the orthogonal direction.

Abstract

A developer container includes a first housing, a rotator drawing a first rotation trajectory in the first housing, a second housing, a developer conveyor in the second housing, and multiple partitions between the first housing and the second housing. The second housing communicates with the first housing. The developer conveyor conveys developer from the second housing to the first housing and includes a rotation shaft and a flexible sheet extending from the rotation shaft. The developer conveyor is rotatable about the rotation shaft to draw an imaginary second rotation trajectory overlapping the first rotation trajectory under an imaginary condition in which the flexible sheet contacts no member and does not bend. The multiple partitions between the first housing and the second housing are arranged at intervals in a rotation shaft direction and are contactable by the flexible sheet rotating around the rotation shaft.

Abstract

An image forming apparatus includes a conveyance device, a printing device, an image reading device, and circuitry. The image reading device reads a print position based on an image formed by the printing device. The circuitry detects an amount of change in the print position that is read relative to a target print position. The circuitry corrects an image position based on the detected amount of change. The image position is a position of an image to be formed on the recording medium in subsequent image formations. The circuitry determines the image position on the second side of the recording medium based on deviations of the print position on the first side of the recording medium from the target print position. The deviations include a deviation at a time of printing the first side, and a post-printing deviation after printing and are the detected amount of change.

Abstract

A wireless apparatus is wirelessly communicable with an information processing apparatus and includes wireless control circuitry and standby control circuitry. The wireless control circuitry stands by for both a peer-to-peer (P2P) connection and an infrastructure connection from the information processing apparatus. The standby control circuitry causes the wireless control circuitry to stop standing by for the P2P connection when the wireless control circuitry is performing the infrastructure connection with the information processing apparatus.
