A printer includes a recording unit, a support portion, a negative pressure chamber, a first sectioned chamber, a second sectioned chamber, a first suction port, and a second suction port. The support portion includes a support face configured to support roller paper. The negative pressure chamber is disposed at an opposite side of the support portion from the recording unit side. The first and the second sectioned chamber include a first and a second bottom surface. The first and the second suction port cause an outside space and the negative pressure chamber to communicate with each other. An opening area of the second suction port is smaller than an opening area of a first suction portion. The second suction port disposed most upstream in the first sectioned chamber is disposed upstream, in the transport direction, of the first suction port disposed most upstream in the second sectioned chamber.

There is provided an image recording apparatus including an image recording head; a scanner; a conveyer; and a controller. The controller is configured to execute first and second recording modes in which the controller causes the image recording head to accelerate to first and second velocities, to move at the first and second velocities, and then to decelerate from the first and second velocities, while causing the image recording head to record the image at least during moving at the first and second velocities, respectively. In a case that the controller has determined, based on printing data, that the image is to be recorded during a first velocity changing period, the controller executes the second recording mode. The first velocity changing period includes a first acceleration and deceleration periods in which the image recording head accelerates and decelerates, respectively.

A printing system includes a media transport system configured to pick a sheet of media from a media supply and transport it along a media transport path to a printing module. An image capture system positioned along the media transport path, includes an image capture device positioned to capture a digital image of the sheet of media, and a platen positioned behind the sheet of media, wherein a surface of the platen includes a non-uniform density pattern, and wherein the captured digital image includes at least one edge of the sheet of media and a portion of the platen that extends beyond the edge of the sheet of media. An image analysis system automatically analyzes the captured digital image to detect an edge position of the sheet of media by detecting a platen region that includes the non-uniform density pattern and a media region.

An image forming apparatus includes: an image forming device forming an image on an image forming medium based on image data; a medium reading device acquiring, on a conveyance path, medium image data representing the image forming medium; an abnormality detector using the image data to generate contrast image region data for specifying an image formation target region that is a region targeted for image formation, using the medium image data to generate contrast medium region data for specifying an image formation permitted region that is a region on the image forming medium where the image formation is enabled, and detecting, as an abnormal region, the image formation target region present outside of the image formation permitted region or a region corresponding to deficiency present within the image formation permitted region; and an abnormality related information output device using the medium image data to output abnormality related information.

A medium-discharging device includes: a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; a light-emitting section that emits light to the medium-receiving tray; and a control section that controls the light-emitting section, in which the medium-receiving tray is configured to switch between a first state in which the medium-receiving tray is stored in an apparatus main body that includes the medium-discharging section and a second state in which the medium-receiving tray protrudes from the apparatus main body, and the control section controls the light-emitting section in accordance with a state or operation of the medium-receiving tray.

A recording device includes an ejecting head ejecting ink onto a medium, a first ink absorber disposed at a position facing the ejecting head and absorbing waste ink, among the ink, ejected to a position beyond an edge during borderless recording, a platen configured to supports the first ink absorber, and support the medium during the borderless recording, a first waste ink tray including a first discharge port discharging the waste ink, the first waste ink tray receiving the waste ink flowing out from the first ink absorber, and a discharge mechanism discharging, from the first discharge port, the waste ink received by the first waste ink tray, wherein the first waste ink tray includes a plurality of inclined regions inclined to guide the waste ink to the first discharge port, and each of the plurality of inclined regions has a different inclination direction.

A printing apparatus includes an image processing unit and generates a product by performing printing on a print medium conveyed in a conveyance direction intersecting a width direction, based on data for printing, and then cutting a width-direction end portion of a printed image, wherein the image processing unit calculates a first ink application amount of a first area formed at one end portion in the width direction on a leading edge side of the image which is located on a downstream side in the conveyance direction during printing and a second ink application amount of a second area formed at the other end in the width direction on the leading edge and enlarges the image data at a predetermined ratio to obtain the data for printing in a case where at least one of the first ink application amount and the second ink application amount exceeds a threshold value.

A medium-discharging device includes: a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; a light-emitting section that emits light to the medium-receiving tray; and a control section that controls the light-emitting section, in which the medium-receiving tray is configured to switch between a first state in which the medium-receiving tray is stored in an apparatus main body that includes the medium-discharging section and a second state in which the medium-receiving tray protrudes from the apparatus main body, and the control section controls the light-emitting section in accordance with a state or operation of the medium-receiving tray.

A printer includes a printing device to print an image on a sheet, a carriage mounting the printing device, the carriage to scan in a main-scanning direction, a detector on the carriage, the detector to detect a presence and an absence of the sheet, and circuitry to detect an edge position of the sheet in the main-scanning direction based on a detection result by the detector while the printing device prints a first scan of the image on the sheet, adjust a print start position at which the printing device starts printing a second scan of the image on the sheet based on the edge position detected in the first scan, and control the printing device to print the second scan of the image from the print start position.
