A conveying device includes a blower and a conveyor. The blower blows air to a sheet material. The conveyor conveys the sheet material through a blowing region of the blower. The conveyor includes a surface movable member and a presser. The surface movable member conveys the sheet material with movement of a surface of the surface movable member, with a back side of the sheet material supported with the surface movable member. The presser presses at least a portion of a leading end of the sheet material toward the surface movable member in at least an area from a position upstream from the blowing region in a conveyance direction of the sheet material to a position in the blowing region of the blower.

Disclosed are a paper discharging mechanism and printing device having the same. The paper discharging mechanism includes: a frame provided with a paper outlet thereon; a swinging rack, configured to be swingable relative to the frame; a conveying roller assembly provided on the swinging rack; a first drive assembly, which is in a transmission connection with the conveying roller assembly and configured to drive the same to deliver a paper to the paper outlet; a first detection assembly, configured to detect a position of the swinging rack relative to the frame; the swinging rack swings in a direction away from the paper outlet when the paper outlet is blocked.

A controller, upon remaining sheets existing in both a print conveyer and a lower conveyer and a sheet size of the sheets being equal to or larger than a specified size upon occurrence of a sheet jam: control an elevator to maintain the print conveyer at a print position, determine to position the print conveyer at a lower limit position in response to removal of the remaining sheet from the lower conveyer, and then drive the elevator to move the print conveyer to the lower limit position; or drive the elevator to move the print conveyer to the lower limit position, determine to position the print conveyer at the print position in response to removal of the remaining sheet from the lower conveyer, and then drive the elevator to move the print conveyer to the print position.

A medium transport apparatus includes a controller that determines how many transport roller pairs disposed on a medium transport route are transporting a medium, based on detection information from detectors disposed in relation to respective transport roller pairs. Then, the controller sets a threshold to a larger value as a larger number of transport roller pairs are transporting the medium and sets the threshold to a lower value as a smaller number of transport roller pairs are transporting the medium.

A printer includes: a printing head configured to perform printing on a medium; a conveyor configured to convey the medium in a conveying direction; a cutter configured to cut the medium to provide a segmented medium; a discharge roller; a counter roller configured to nip the medium in cooperation with the discharge roller; a driver configured to rotate the discharge roller in a discharging direction; and a controller configured to perform: (a) controlling the printing head and the conveyor to perform the first print control based on a first print instruction to perform printing on the medium; (b) driving the driver to stop rotation of the discharge roller with the medium nipped between the discharge roller and the counter roller; and (c) driving, when a second print control subsequent to the first print control is allowed, the driver to rotate the discharge roller in the discharging direction.

Provided is a printing apparatus that allows the user to easily perceive that the cover is unlocked. In the printing apparatus that includes: a cover unit configured to expose the conveying path, along which the printing medium is conveyed, to the outside when the cover unit is opened and that shields the conveying path when the cover unit is closed; and a locking configured to lock the cover unit to keep it closed, and that performs printing on the printing medium being conveyed along the conveying path, the cover unit is urged by an urging unit in the opening direction. In addition, when the locking unit unlocks the cover unit the cover unit is opened by a predetermined degree by the urging force of the urging unit.

A coating apparatus is connectable to both an image forming apparatus and a sheet feeder. The coating apparatus includes a coater, a carry-in entrance, and an ejector. The coater coats a recording medium with a treatment liquid. The carry-in entrance is on one of two exterior wall surfaces facing each other. The recording medium is conveyed from the sheet feeder through the carry-in entrance. The ejector is on another of the two exterior wall surfaces. The ejector ejects the recording medium to the image forming apparatus. A position of the carry-in entrance on the one of the exterior wall surfaces matches a position of the ejector on said another of the exterior wall surfaces.

An image forming apparatus includes a controller circuitry configured to control the ink-jet module to form a density adjustive image pattern on one of the multiple sheets, detect a jam during continuous feeding, and then determine whether or not images, which are to be formed on one or more fed-and-unejected sheets, include the density adjustive image pattern, where the images include the density adjustive image pattern, determine whether or not the unejected sheet, on which the density adjustive image pattern is to be formed, has passed through a certain position of the sheet conveyer path, and control the ink-jet module, where the unejected sheet, on which the density adjustive image pattern is to be formed, has passed through the certain position, not to re-form the density adjustive image pattern and to re-form images on rest of the unejected sheets.

A sheet feeding device includes a support that detachably supports a roll, a rotation driver that rotates a spool, a guide including a facing portion and a guide portion, a support shaft that swingably supports the guide, a biasing member that presses the guide, a sensor that retractably projects from the facing portion and outputs a detection signal, a roller that contacts an outer circumferential surface of the roll, and circuitry that controls the rotation driver. The circuitry determines a passing time based on a first change rate and a second change rate, and causes the rotation driver to rotate the spool by a predetermined angle in a winding direction, from the passing time, to position a leading end of a continuous sheet at a feeding start position, and rotates the spool in the feeding direction to feed the continuous sheet from the feeding start position along the guide portion.

A printer includes a head having nozzles, a carriage with the head mounted thereon, a carriage motor to move the carriage along a scanning direction, an encoder including a scale having reference marks formed thereon along a particular direction, and a sensor to detect the reference marks while moving relative to the scale along with movement of the carriage along the scanning direction, and a controller configured to perform liquid discharging to control the head to discharge liquid from the nozzles toward a recording medium while performing feedback control of the carriage motor based on velocity information such that the carriage moves at a target velocity along the scanning direction, the velocity information representing a carriage velocity based on detection results of the sensor, and interrupt the liquid discharging when the carriage velocity exceeds an overshoot threshold higher than the target velocity during the liquid discharging.
