A printing apparatus includes a moving unit configured to relatively move a printing medium and a discharging unit configured to discharge a liquid onto the printing medium; and a control unit configured to obtain information related to a speed of airflow at a discharge port surface of the discharging unit and, based on the obtained information, control an adjustment operation for adjusting a density of a solid component of the liquid. A printing mode is selectable from a plurality of types of printing modes. The information includes information identifying a type of a selected printing mode.

According to one embodiment, a printer device includes regulating members provided in a conveyance path of paper or an accommodation unit of the paper, and regulating side edges of the paper in a width direction and having a variable regulating width, a detection unit configured to detect a paper width of the paper based on the regulating width of the regulating members, and a processor. The processor is configured to store the paper width detected by the detection unit in a storage unit, control printing of the paper in the width direction based on the paper width stored in the storage unit, and update the paper width stored in the storage unit according to a variation in the paper width if the paper width newly detected by the detection unit is varied from the paper width stored in the storage unit.

A media processing device includes: a print head extending across a media path, and configured to apply indicia to media; a platen roller assembly adjacent to the print head, the print head configured to draw the media from a media supply along the media path travelling between the print head and the platen roller assembly, the platen roller assembly including: (i) a first platen roller extending across a first portion of a width of the media path, and (ii) a second platen roller coaxial with the first platen roller, and extending across a second portion of the width of the media path; a drive assembly coupled with the first and second platen rollers, the drive assembly configured to selectively drive rotation of either or both of the first and second platen rollers.

A processing device includes a support table to support a sheet medium, a sheet cutter to cut the medium supported on the support table, a cutter holder to move the sheet cutter in a toward-away direction in which the sheet cutter moves toward and away from the support table, and a cutter transporter to move the cutter holder in a cutting direction that is orthogonal to a transport direction of the medium. The cutter holder includes a holder movable in the toward-away direction and that holds the sheet cutter, an actuator including a rod that extends or retracts, a link connected to the rod and the holder, and a rotation shaft that rotatably supports the link so that the holder moves in the toward-away direction in response to extension or retraction of the rod.

A recording apparatus includes a cassette or a feeding tray that is configured to mount a medium thereon, a transport unit that transports the medium mounted on the cassette or the feeding tray, and a recording head that performs recording on the medium. Furthermore, the recording apparatus includes a medium detection device and a deviation amount acquisition section. The medium detection device detects at least one of both side edges in a width direction intersecting a transport direction of the medium that is transported from the cassette or the feeding tray (step S12). The deviation amount acquisition section acquires a deviation amount of the recording head in the width direction of the medium based on at least one side edge detection position detected by the medium detection device (step S13).

An image forming apparatus includes a first conveyance processing portion, a second conveyance processing portion, and an expansion/contraction processing portion. The first conveyance processing portion conveys a sheet. The second conveyance processing portion conveys the sheet after the conveyance of the sheet by the first conveyance processing portion. The expansion/contraction processing portion expands or contracts the size of an image to be formed by an ejection portion that ejects ink when it is determined that the same sheet as the sheet conveyed by the first conveyance processing portion has been conveyed by the second conveyance processing portion in an orientation different from that when the sheet was conveyed by the first conveyance processing portion.

An image forming apparatus includes a first stacking portion, a second stacking portion, a conveyance portion, an error detection portion, and a control portion configured to control the conveyance portion. The control portion is configured to execute (i) a first recovery operation in a case where the first error is detected, the first recovery operation being an operation that is executed to recover from the first error, and that controls the conveyance portion to discharge a sheet to the first stacking portion and not to discharge a sheet to the second stacking portion, and (ii) a second recovery operation in a case where the second error is detected, the second recovery operation being an operation that is executed to recover from the second error, and that controls the conveyance portion to discharge a sheet to at least one of the first stacking portion and the second stacking portion.

A medium ejecting apparatus includes a conveyance roller to convey a medium, a processing device to perform a predetermined processing relative to the medium conveyed by the conveyance roller, an ejection roller located downstream from the processing device in a medium ejecting direction to eject the medium subjected to the predetermined processing, a motor to drive the conveyance roller and the ejection roller, a first media sensor located between the conveyance roller and the processing device to detect the medium, and circuitry. The circuitry detects a skew amount of the medium, and controls the ejection roller based on a detection result by the first media sensor and the skew amount before a trailing end of the medium passes the ejection roller.

When discharging a sheet onto a discharge tray, a control unit sets position of the discharge tray in an up and down direction to a predetermined discharge position. When loading the sheet onto a processing tray, the control unit sets the position of the discharge tray in the up and down direction to a loading position lower than the discharge position.

The invention is a structure and a method for automatically measuring a paper size for a printer, where the structure includes: a width adjustment mechanism installed in the printer, at least one restraint arm driven by the width adjustment mechanism, a photoelectric sensor installed at a paper inlet of the printer, and a paper feeding module, where an inductor is also arranged inside the printer, and the width adjustment mechanism or the restraint arm triggers the inductor when sliding unidirectionally. Benefits of the present invention are as follows:
