Abstract: A printing apparatus includes a print unit; a first roller that transport the medium; a plurality of second rollers cooperating with the first roller to nip the medium therebetween at positions that face the first rollers; a third roller that holds the medium which has been transported by the first roller and transport the medium to a print path in which printing is performed by the print unit; a specific second roller located most downstream in the transportation path among the second rollers; and a control unit that controls each of the roller and the print unit, wherein the control unit causes the specific second roller to be displaced to a separated position after the medium is held by the third roller.

Abstract: When printing is performed on a medium, a computer of a printing apparatus acquires a space (a PLG level number and a thickness of the medium) between a surface of the medium and a print head, which is formed when an ink is discharged onto a medium from the print head in a printing unit. A high speed/low speed of a carriage speed (print speed mode), print color (monochrome/color), and a transport region (normal region/lower end region) as a transport position of the medium are determined. A calculation expression is selected according to the carriage speed, the print color, and the transport region, and a correction amount according to a gap length is calculated using the selected calculation expression. Also, the transport distance is corrected using the correction amount. Transport control is performed by the transport distance.

Abstract: A serial inkjet printer includes a recording head having a plurality of nozzles between which a pitch is X inches, a carriage, a first roller pair, and a second roller pair. The first roller pair is configured to move a medium at an upstream side of a conveyance direction of the medium relative to the recording head, and includes a drive roller with a hollow structure and a driven roller. A circumferential length Y of the drive roller is 2 to 4 inches. When a length along the conveyance direction of a row formed by the nozzles is Z inches, Y is greater than Z. While repeating scanning of the recording head and conveying of the medium, recording is performed in band units at a printing speed of 20 to 30 ipm, and stop error precision of the medium during conveyance is X/2 inches or less.

Abstract: A printer includes a pair of input rollers, a pair of output rollers, a print head and a control section. The control section is configured to transport a print medium by rotating the input rollers and the output rollers after printing on a target region and before printing on a next target region. The control section is configured to determine, before carrying out transporting, whether a combination of the input rollers and the output rollers which pinch the print medium would change in a case where the print medium were transported from a current position to a next target position, and, in a case where there would be a change, the control section being configured to transport the print medium from the current position to the target position in a retracted state where the print head is moved to an outside of a range where the print medium passes.

Abstract: A print apparatus includes a conveyance unit configured to convey a print medium over a plurality of convexities that are arranged along a direction of scanning and the control unit. When one end position of the print medium has been detected by a detection unit, in a case where the one end position is a position that overlaps with position of the convexities stored in a storage unit, the control unit is configured to control a detection of the other end position of the print medium and determine the one end position on the basis of the other end position.

Abstract: When a paper jam is detected, in the case where the cause of the paper jam is a CR motor error in which the speed of the carriage is decreased by as much as a load when the paper jam occurs and becomes equal to or less than a set speed, when there is an instruction to continue printing, cleaning is performed on a printing head. In this case, it is determined whether the paper position is particularly in a one-side supporting range in which the paper is supported by only one pair of transporting roller pairs provided in each of an upstream side and a downstream side of a transporting direction of the paper with interposing of a moving path of the printing head. Then, it is preferable that cleaning be performed as long as the paper position is in the one-side supporting range.

Abstract: A medium discharge device includes: a discharge unit that discharges a medium; a first medium receiving tray that receives the medium discharged by the discharge unit; and a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit. The second medium receiving tray is capable of changing a position between an advance position for receiving a medium, which is discharged, by causing at least an upstream zone of the tray including an upstream side end portion in a medium discharge direction to advance to a passing route of the medium from the discharge unit toward the first medium receiving tray and a retraction position to which the upstream zone retracts from the passing route.

Abstract: A printing apparatus that is capable of executing, based on printing data, printing onto a first side of a printing medium and printing onto a second side, which is the back side of the first side, after the printing onto the first side is provided. A print density of a predetermined region at a rear end of the printing medium in a transporting direction at a time of printing of the first side is identified based on the printing data. Conversion data, which is a conversion coefficient to make the identified print density equal to or lower than a predetermined density, is acquired. The printing data is converted by means of the conversion data. Printing onto the first side is executed based on the converted printing data.
