A printing apparatus includes a first roller pair configured to convey a continuous medium, a printing head that is located downstream of the first roller pair and that performs printing on the continuous medium, a cutting unit that is located downstream of the printing head and that is configured to cut the continuous medium, a second roller pair that is located downstream of the cutting unit and that is configured to convey the continuous medium, a common driving source configured to apply driving force to the first roller pair and the second roller pair, and a clutch mechanism configured to cut power from the driving source to the second roller pair, wherein the clutch mechanism is a one-way mechanism that transmits the power when the continuous medium is conveyed in a forward direction and does not transmit the power when the continuous medium is conveyed in a reverse direction.

Printing apparatus

A printing apparatus includes a first roller pair that sandwiches and conveys a continuous medium, a printing head that is located downstream of the first roller pair in a conveying direction of the continuous medium and that performs printing on the continuous medium, a cutting unit that is located downstream of the printing head in the conveying direction of the continuous medium and that cuts the continuous medium, a second roller pair that is located downstream of the cutting unit in the conveying direction of the continuous medium and that sandwiches and conveys the continuous medium, a common driving source that applies driving force to the first roller pair and the second roller pair, and a clutch mechanism configured to cut power from the driving source to the second roller pair, wherein the clutch mechanism is an electromagnetic mechanism that releases transmission of the power by electromagnetism.

To improve cleaning properties of a transport belt which transports a recording medium. A recording apparatus includes a transport belt () which supports and transports a recording medium (P), a recording head () through which ink is discharged onto the recording medium (P), and a cleaning portion () for the transport belt (). The recording apparatus has a first cleaning mode in which the cleaning portion () cleans the transport belt () during transporting of the recording medium (P) by the transport belt () and a second cleaning mode in which the cleaning portion () cleans the transport belt () during a period except for transporting of the recording medium (P) by the transport belt ().

Recording apparatus and cleaning method of transport belt

A printing apparatus includes a transporting section that transports a work, a printing mechanism section that has a nozzle plate that performs printing by discharging ink on the work, and a moving section that reciprocally and relatively moves the printing mechanism section in a direction intersecting the transporting direction of the work. In the printing apparatus, when the printing mechanism section moves reciprocally, printing in a forward path includes a first printing area, a second printing areas, and printing in a backward path includes a first printing area, and second printing areas. In addition, the transportation amount of the work is adjusted based on the second printing areas.

Printing apparatus and printing method

A recording apparatus includes a transportation belt, a washing portion that washes the transportation belt, and a selection unit. The selection unit selects a transportation mode for transporting the recorded medium from among a washing transportation mode in which the transportation belt is transported while being washed by the washing portion, and a non-washing transportation mode in which the transportation belt is transported without being washed by the washing portion. The selection unit selects the transportation mode in accordance with a recording mode. The selection unit selects, as a transportation mode for use in transporting the recorded medium along with no recording operation after a recording operation onto the recorded medium has been brought to a halt, the washing transportation mode or the non-washing transportation mode, whichever has been selected in the recording operation having been brought to a halt.

Recording apparatus and method for transporting recorded medium

A method is for notifying information of a remaining amount of a recording medium in a recording apparatus including a delivery section that rotates and delivers a roll-shaped recording medium, a transport belt that transports the recording medium delivered from the delivery section, and a slack sensor that detects a slackened state in the recording medium delivered from the delivery section to the transport belt. The method includes notifying the information of the remaining amount of the recording medium if the slack sensor detects a lack of slack of the recording medium in a period of a first time or more.

The medium feed device has a meandering detection sensor which detects position displacement of a recording medium in a width direction, and a control section which controls driving of a width movement unit based on detection results by the meandering detection sensor. The control section stops driving of the width movement unit when stopping feeding of the intermittent feeding.

Recording device

A recording apparatus includes a transportation belt that transports a recorded medium; a washing portion that washes the transportation belt; and a selection unit that selects a transportation mode for transporting the recorded medium from among a washing transportation mode in which the transportation belt is transported while being washed by the washing portion, and a non-washing transportation mode in which the transportation belt is transported without being washed by the washing portion.

The advantage of the invention is to provide a medium feed device and the like for intermittently feeding a recording medium in which meandering can be securely corrected without the occurrence of wrinkles in the recording medium. The medium feed device has a meandering detection sensor which detects position displacement of a recording medium in a width direction, and a control section which controls driving of a width movement unit based on detection results by the meandering detection sensor. The control section stops driving of the width movement unit when stopping feeding of the intermittent feeding.

Medium feed device, method for controlling medium feed device, and recording device

A recording apparatus includes a delivery section that rotates and delivers a roll-shaped recording medium; a transport belt that transports the recording medium delivered from the delivery section; a slack sensor that detects a slackened state in the recording medium delivered from the delivery section to the transport belt; and a control section that performs low speed transport control for controlling the transport belt such that the recording medium is transported by decreasing a transport speed of the recording medium depending on the transport belt if the slack sensor detects a lack of slack of the recording medium in a period of a first time or more.

A cleaning apparatus includes a first cleaning roller, and a second cleaning roller. The first cleaning roller is contrived to contact to a circumferential surface against a moving member to be cleaned and to apply a bias to the member to be cleaned while rotating such that the circumferential surface of the first cleaning roller moves in a same direction as the member to be cleaned moves. The second cleaning roller is contrived to contact to the member to be cleaned after the member has been cleaned by the first cleaning roller and to rotate such that a circumferential surface of the second cleaning roller moves in a direction opposite a direction in which the member being cleaned moves.

Cleaning apparatus and image forming apparatus

In a color printing mode of an image forming apparatus, two toner images in respective colors are formed and superimposed on an intermediate transfer belt. A gap Dbetween toner images of the same color is narrowed while a gap Dbetween toner images of different colors is widened, thereby corresponding to the switching of developers. In a printing mode that forms a monochrome image using one developer, gaps D, Dbetween the respective toner images are the same. In a printing mode that forms a monochrome image while switching four developers, a toner image formed immediately before the switching is shifted forward, thereby widening a gap Dfrom the next toner image.
