A recording apparatus includes a liquid container configured to contain, outside a recording area of the recording apparatus, liquid to be supplied to a recording head configured to perform recording by discharging the liquid to a recording medium in the recording area, a maintenance unit disposed outside the recording area, including a suction unit configured to suck the liquid from the recording head, and configured to carry out maintenance of the recording head, and a liquid reservoir portion below the liquid container and the maintenance unit.

Recording apparatus

A liquid discharge apparatus includes a container, a passage, first and second cover portions, and a valve unit. Liquid is injected into the container through an injection portion and supplied from the container through the passage to the liquid discharge head. The first cover portion pivots on a first axis as a center between an open position to allow access to the injection portion and a close position to not allow access to the injection portion. The second cover portion pivots on a second axis intersecting the first axis and as a center between an open position of the second cover portion to expose the first cover portion and a close position of the second cover portion to cover the first cover portion. The valve unit switches to an open state to open the passage when the second cover portion pivots from the open position to the close position.

Liquid discharge apparatus

A sheet is cut between a first conveying unit and a second conveying unit in a state in which the first and second conveying units halt and in which an upstream conveying unit conveys the sheet at a first speed; after the sheet is cut, the first conveying unit conveys the sheet at a second speed higher than the first speed to reduce a slack formed during the halting; after the sheet is cut, the second conveying unit conveys the downstream-side sheet at a third speed higher than the first speed; if the third conveying unit is nipping the sheet during cutting, the third conveying unit conveys the sheet at the third speed; and if the third conveying unit is not nipping the sheet, the third conveying unit conveys the sheet at the third speed or a fourth speed after the detecting unit detects the sheet.

Apparatus and method for cutting sheet

A sheet cutting apparatus includes a cutting unit configured to cut a sheet, a discharge unit configured to discharge a fragment of the sheet cut by the cutting unit, a blowing unit configured to blow air on the fragment discharged from the discharge unit, and a storage unit configured to store the fragment discharged from the discharge unit.

Sheet cutting apparatus and printer, and sheet handler provided therewith

In the case of performing duplex printing on a continuous sheet, by setting a length of a non-image area to an optimum length, both of mark detection having high reliability and the suppression of a sheet consumption amount are achieved. For this purpose, when duplex printing of a plurality of images on front and back surfaces of the continuous sheet is performed, on the basis of a length of the image to be printed precedently to a non-image area Won the second surface, the length of the non-image area common to the front and back surface is set.

Printing apparatus and printing method

At least one of processing units is capable of being pulled out of a main body of an apparatus during the occurrence of a sheet conveyance jam. A first cutter and a second cutter are arranged in the vicinity of the processing unit. The first cutter is configured to cut the sheet on an upstream of the processing unit. The second cutter is configured to cut the sheet on a downstream thereof. When the processing unit is pulled, the sheet is cut on the upstream and downstream of the processing unit.

Printing apparatus and sheet processing apparatus

A sheet conveyance apparatus including a conveyance unit configured to convey a sheet, wherein the conveyance unit includes a slanting surface having an inclination with respect to a horizontal surface and a conveyance surface that forms, together with the slanting surface, a space that becomes narrower downward in the vertical direction and which moves in a predetermined direction, and conveys the sheet in a predetermined direction by the movement of the conveyance surface.

Sheet conveyance apparatus, sheet cutting apparatus, and image forming apparatus

A sheet cutting device includes a conveyance unit configured to convey a sheet, a cutting unit configured to cut the sheet conveyed by the conveyance unit, and a conveyance belt configured to convey a cut piece cut from the sheet cut by the cutting unit in a direction orthogonal to a conveyance direction of the conveyance unit.

Sheet cutting device and printer

A control unit includes a memory storing correction data obtained by associating information acquired by a first acquisition unit (rotary encoder) with information acquired by a second acquisition unit (direct sensor) with respect to, at least one rotation of a conveying roller. When a plurality of images are sequentially printed on a first surface and a second surface of a continuous sheet, the control unit reads the correction data corresponding to the rotation information acquired by the first acquisition unit from the memory and corrects at least one of driving control of a print head and driving control of the roller. The correction data used in printing on the first surface of the sheet is different from that used in printing on the second surface of the sheet.

Printing apparatus

A reference mark is formed for cutting a sheet in a region between a first image printed on the sheet being conveyed and a second image, and the sheet is cut based on the detected reference mark. The second image is printed such that the length of the region in a conveying direction in which the sheet is conveyed corresponds to the length of the first image in the direction.

Method of printing and printing apparatus

A device includes a winding rotary member having a cylindrical shape; a holder having a rotating member, which is provided in the vicinity of a cylindrical surface of the winding rotary member, capable of nipping and conveying the sheet; a first driving mechanism configured to rotate the winding rotary member; and a second driving mechanism configured to rotate the rotating member. The winding rotary member rotates with the sheet is nipped with the rotatable holder, whereby the sheet is wound around the winding rotary member.

Printing apparatus, sheet processing apparatus, and sheet winding device

A sheet conveyance apparatus comprising: a first processing unit including a first sheet conveyance mechanism; a second processing unit including a second sheet conveyance mechanism; a cutting unit, interposed between the first processing unit and the second processing unit, for cutting the sheet; and a controlling unit that controls, in a case of trouble with sheet conveyance, driving of the first sheet conveyance mechanism until an end of the sheet reaches the first processing unit side beyond a cutting position of the cutting unit.

Sheet conveyance apparatus, printing apparatus, and jam clearing method

A method includes pulling out and conveying a sheet having splice portions, acquiring information relating to a position of an indentation on the sheet formed in addition to a splice portion, and performing processing on the sheet but a position corresponding to the acquired position of the indentation and its vicinity.

Recording apparatus and sheet processing method

In the event that occurrence of a jam has been detected during conveyance of a sheet, the sheet is cut at a cutter unit, and a user is prompted to perform manual jam restoration processing according to the location where the jam has occurred. If the jam has occurred upstream from the cutter unit, the cut sheets left downstream from the cutter unit are discharged as completed articles.

Printing apparatus and jam restoration method in printing apparatus

In a first step, a sheet is conveyed in a direction, whereby a leading end portion of the sheet is fed to a position between a decurl roller and a decurl pinch roller, which are in positions spaced apart from each other. In a second step, the leading end portion of the sheet is curved and held by causing the decurl pinch roller to come close to or press against the decurl roller. In a third step, the leading end portion of the sheet is withdrawn from between the decurl roller and the decurl pinch roller by conveying the sheet in a direction opposed to the conveying direction. After executing the first to third steps, the sheet is conveyed in the conveying direction through the first step while the sheet is curved by the decurl roller.
