A recording system that when formation of the image is restarted after a temporal stop of the formation of the image by temporarily stopping the conveyance of the recording target medium by the first conveyance unit and the discharging of the ink from the discharging part, a distance from a first position to a recording restart position is an integer multiple of image formation pitch, the first position being based on a position, at the time of the temporal stop, of the image that is formed on the recording target medium before the temporal stop, the recording restart position being a position where the ink is discharged at the time of the restart; and performing the post-processing on the recording target medium at the post-processing unit each time the recording target medium is conveyed, by the second conveyance unit, a distance corresponding to the image formation pitch.

Recording system, recording apparatus and recording method

A circuit unit includes a circuit board, a cover being configured to house the circuit board inside, a first airflow inlet formed in a first surface of the cover, and a first duct formed in the first surface wherein the first duct is in communication with the first airflow inlet, and a sliding mechanism that supports the circuit unit such that the circuit unit is movable, the sliding mechanism includes a fixed frame, a second airflow inlet formed in the fixed frame, and a second duct that is formed in the fixed frame and in communication with the second airflow inlet, and, when the circuit unit is located at the first position, the first duct and the second duct are engaged with each other such that a third duct is formed to cause the first airflow inlet and the second airflow inlet communicate each other.

Printing apparatus

Technology enabling accurately detected marks on a print medium according to the type of print medium is provided. A printerhas a media type identifierthat determines the type of medium; a mark sensorthat projects light and detects a mark on the medium; and an emittance controllerthat sets the emittance level of the light the mark sensorprojects. The printercan change the operating mode according to the type of medium M identified by the media type identifier. In the white medium mode, the mark sensordetects a mark MR with the emittance level set to a white medium emittance level. In the non-white medium mode, the mark sensordetects a mark MR with the emittance level set to a non-white medium emittance level, which is higher than the white medium emittance level.

Printer and control method of a printer

A printing apparatus includes a transport unit which transports a recording medium in a transport direction; a printing unit which prints an image and a mark on the recording medium; and a mark detecting unit which is located on an upstream side of the printing unit in the transport direction, and detects a mark, includes a function of automatically adjusting a detecting sensitivity of the mark detecting unit, and obtains a printing start position using the mark, in which the mark detecting unit has a timer function including an ON delay in which a time between detecting of a mark and outputting of a detecting signal of ON is delayed, uses the timer function when obtaining the printing start position, and does not use the timer function when performing the automatic adjusting.

Printing apparatus and printing method

A printing apparatus includes: a driving roller configured to drive a recording medium by rotation thereof while being in contact with the recording medium; a discharging head configured to discharge liquid onto a recording medium; a driven rotational member configured to be driven to rotate as a result of transport of the recording medium while being in contact with the recording medium; a rotation position detection unit configured to detect a rotation position of the driven rotational member; and a control unit configured to rotate the driving roller to transport the recording medium and adjust a timing of discharging the liquid from the discharging head in accordance with a detection result of the rotation position detection unit. The control unit adjusts a rotational speed of the driving roller in accordance with a linear pressure applied to the recording medium on the driving roller.

An output value of the transport position output portion when a first mark which is provided in a recording medium is at a predetermined position with respect to a detection region is stored in a storage portion as a reference value, and a start timing of the printing of the image is controlled based on the timing at which the mark detection portion detects the mark after confirming that the first mark reaches a predetermined range from the detection region based on comparison of the output value of the transport position output portion and the reference value with each other, when the transport in the first direction of the recording medium is started.

A rotation shaft configured to rotate in a direction in which a sheet is fed in and in a direction in which the sheet is wound while supporting the sheet, a control unit configured to apply tension to the sheet by the rotation shaft by controlling torque applied to the rotation shaft, an ejection unit configured to eject light-curable liquid onto the sheet, and an irradiation device configured to irradiate light onto the liquid ejected onto the sheet by the ejection unit are provided. The tension applied to the sheet by the rotation shaft when the rotation shaft rotates in the direction in which the sheet is wounded is smaller than the tension applied to the sheet by the rotation shaft when the rotation shaft rotate in the direction in which the sheet is fed in.

Image recording apparatus and sheet transfer method

A liquid ejecting apparatus includes: a transportation section that transports a medium in a transportation direction; a head that ejects the liquid on the medium; a support member that supports the medium which is in a position facing the head while abutting a surface of one side of the medium; a heat source that is disposed in a position facing the support member; an abutting member that abuts the surface of the one side of the medium on an upstream side from the support member in the transportation direction; and a detection section that detects presence or absence of the foreign matter on a surface of the other side of the medium in an area of the medium which abuts the abutting member.

Liquid ejecting apparatus and method for detecting foreign matter

An image recording device including a transport unit that transports a recording medium from a first drive roller to a second drive roller by rotating a first drive roller and a second drive roller across which a recording medium is stretched, a support member that supports the recording medium between the first drive roller and the second drive roller, a recording unit that ejects liquid on the recording medium supported on the support member and records an image, a detection unit that detects tension of the recording medium moving toward the second drive roller away from the support member, and a control unit that gives tension to the recording medium by controlling the torque of the second drive roller based on the recording medium tension detected by the detection unit.

Image recording device, and image recording method

An image recording apparatus includes a recording unit that records an image in a first region, a first control unit that has a drive roller to transport a recording medium and controls a tension of the recording medium in the first region by adjusting a torque of the drive roller based on the tension of the recording medium in the first region, a second control unit that controls the tension of the recording medium in a second region according to the detection result of the tension of the recording medium in the second region. Compared to the frequency response characteristics of the first control unit with respect to the tension fluctuations generated in the first region, the frequency response characteristics of the second control unit with respect to the tension fluctuations generated in the second region responds to the tension fluctuations having a higher frequency band.
