A print control device includes a controller. The controller edits an image constituted by one or more objects including one or more upper objects, acquires an image area length, an image area width, a lower tape length, and a lower tape width, designates one upper object from among the one or more upper objects, and acquires an object area length, an object area width, and an upper tape width. In a case where a precondition is met for the designated upper object, the controller sets an orientation to a parallel orientation when a first condition or a third condition is met, and sets the orientation to an orthogonal orientation when a second condition or a fourth condition is met. The controller issues an error notification when the precondition is met but all of the first condition, the second condition, the third condition, and the fourth condition are not met.

An image processing apparatus includes a size acquisition unit and a decision unit. The size acquisition unit acquires first size information indicating a first sheet size of a first sheet surface read by an image reading unit. The decision unit decides second image information indicating a second image size of a second image to be stored of a second sheet surface different from the first sheet surface based on first image information indicating a first image size of a first image to be stored based on the first size information.

A medium transport apparatus includes a medium transport path through which a medium passes, a path state detection section configured to output a detection value corresponding to a state of the medium transport path, a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, and a storage configured to store history information including the detection value acquired in the past, in which the control section changes the threshold value based on the history information.

A reading device is configured to detect an edge position of a target object to be conveyed in a conveyance direction. The edge position is a position of an edge of the object in a width direction intersecting the conveyance direction. The reading device includes a sensor device, an adder, and an edge position detector. The sensor device includes a pixel array including a plurality of elements arranged in the width direction. The adder is configured to add detection signals output from the elements at respective positions in the width direction. The edge position detector is configured to detect the edge position on basis of a position at which an output of the adder changes to a value larger than a threshold. Each element is configured to output a detection signal based on a reception amount of light in one of different wavelength bands.

At the time of copying a smaller document and a larger document on output sheets having the same size, in a first case where a first document is smaller and a second document is larger, a printing control unit analyzes a content of the second document, and copies the first document and the second document on output sheets having sizes corresponding to the analysis result. In a second case where the first document is larger and the second document is smaller, a content of the first document is analyzed, and the first document and the second document are copied on output sheets having sizes corresponding to the analysis result.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A reading device includes a position reference member and a reader. The position reference member has a reference pattern that includes a line extending in a prescribed direction. The position reference member is configured to relatively move in a direction orthogonal to the prescribed direction. The reader includes a plurality of sensor chips, each of the sensor chips including a plurality of pixels. The reference pattern corresponds to each of the sensor chips of the reader.

A medium conveying apparatus includes a plurality of feed rollers spaced in a direction perpendicular to a medium conveying direction, each of the feed rollers rotating independently at a respective speed to feed a medium, a plurality of brake rollers, each of the plurality of brake rollers being located to face a corresponding one of the plurality of feed rollers, a plurality of torque limiters separately provided between one of rotation shafts of the plurality of brake rollers and a corresponding one of the plurality of brake rollers, and a processor to detect a skew of the medium, and correct the skew of the medium by changing the speed of one of the plurality of feed rollers when the skew of the medium is detected.

At the time of copying a smaller document and a larger document on output sheets having the same size, in a first case where a first document is smaller and a second document is larger, a printing control unit analyzes a content of the second document, and copies the first document and the second document on output sheets having sizes corresponding to the analysis result. In a second case where the first document is larger and the second document is smaller, a content of the first document is analyzed, and the first document and the second document are copied on output sheets having sizes corresponding to the analysis result.

An image forming device and an image forming system which can perform a sheet setting process for a sheet on which an image or text has already been formed, an image forming system control method, and a non-transitory computer-readable recording medium storing a program. The image forming device includes a communication section, a determination section, and a notifying section. The communication section receives, from a sheet detector for detecting a physical property value of a sheet, detected information acquired by detecting the sheet. The determination section determines whether the detected information meets a given condition or not. If the determination section determines that the given condition is not met, the notifying section notifies a user that the given condition is not met.
