An image reading device includes a first scanner, a second scanner, and circuitry. The first scanner is configured to read a first side of a recording medium. The second scanner is configured to read a second side of the recording medium. The circuitry is configured to generate a first correction value to correct misalignment between the first side and the second side. The circuitry is configured to input a second correction value. The circuitry is configured to correct an image based on the first correction value and the second correction value.

An image forming apparatus includes a conveyance part, an image forming part, a sheet detection sensor, a sensor unit, and a controller. The sheet detection sensor, in which a plurality of sensor blocks each with a plurality of sensor elements mounted thereon at specified intervals are arrayed in a sheet width direction, detects an edge position in the sheet width direction on a basis of scanning image data formed by reading of the sheet. The controller is enabled to execute a calibration of inserting, into the scanning image data, interpolation pixels for compensating an error between an edge position detected by the scanning image data and an actual edge position.

In an image recording apparatus, a peak load that is the highest load applied to a carriage moving in a first direction in a first load region is highest at a first highest-load position. A second load is highest at a second highest-load position of a second load region. In a retry processing, when a stop position of the carriage which is detected by a detector is located between the first highest-load position and the second highest-load position, the controller moves the carriage in the first direction toward a target position after moving the carriage from the stop position in a second direction to a first retry position located downstream of a restoration position in the first direction.

A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars distributed along a media transport. A first image including a reference pattern is generated on a print medium with a first printbar. A pattern is then detected on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar. This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

An image sensor unit includes: a light condenser that collects light from the reading target object; an image sensor that receives the collected light collected and converts it into an electric signal; a housing having an elongated shape housing the light condenser and image sensor; and an elongated rigid member provided on a side surface elongated in an elongated direction of the housing. The housing has a multiple positions for fixation on the side surface. The rigid member is fixed to the side surface of the housing at at least two positions. A warping amount adjusting part is provided between the positions at which the rigid member is fixed. The warping amount adjusting part is capable of holding warping amount in the direction of the optical axis of the light condenser of the housing by intervention of a warping amount adjusting member between the rigid member and the housing.

A printing apparatus comprises: a printer that includes a printing mechanism that performs printing on a printing medium, the printing mechanism being provided in a print area; a housing that includes an opening region for exposing the printing mechanism to outside; and a guiding mechanism that represents a position of the print area. The guiding mechanism is provided at a position directly above the print area and visible from outside. Accordingly, when a user performs printing on the printing medium using this printing apparatus, the user can easily grasp a position of the print area by means of the guiding mechanism, and therefore can print on a desired position on the printing medium.

A method and system for generating a three-dimensional (3D) map of an environment is provided. An example method includes receiving, by a processor system, via a 3D scanner, located at a scan position, a 3D scan of the environment. The method further includes receiving via a two-dimensional (2D) scanner accessory, a portion of a 2d map of the environment. The method further includes receiving coordinates of the scan position in the 2d map in response to the 3D scanner initiating the acquisition of the 3D scan. The method further includes associating the coordinates of the scan position with the portion of the 2D map. The method further includes determining a displacement vector for the 2D map using a loop closure algorithm. The method further includes computing a revised scan position based on the scan position and the displacement vector, where the 3D scan is registered using the revised scan position.

In an image recording apparatus, a peak load that is the highest load applied to a carriage moving in a first direction in a first load region is highest at a first highest-load position. A second load is highest at a second highest-load position of a second load region. In a retry processing, when a stop position of the carriage which is detected by a detector is located between the first highest-load position and the second highest-load position, the controller moves the carriage in the first direction toward a target position after moving the carriage from the stop position in a second direction to a first retry position located downstream of a restoration position in the first direction.
