Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

There is provided a printing apparatus including: a holder configured to accommodate a printing medium; a conveyor configured to convey the printing medium along a conveying direction; a printer; a cutter configured to cut the printing medium; a first detector configured to detect front and rear ends of the printing medium; and a controller. A distance in the conveying direction between the first detector and the cutter is shorter than a length of one of media generated by dividing the printing medium into n-pieces of media. The controller is configured to: calculate a length in the conveying direction of the printing medium by using a result of the detecting of the front and rear ends, and set a cutting position of the printing medium; and cause the cutter to cut the printing medium at the set cutting position.

A postprocessing device includes a processing tray, a first transport roller, a second transport roller, a sidetrack, a sidetrack roller, and a controller. The controller shunts a preceding recording medium to the sidetrack by rotating the sidetrack roller, determines, on a basis of a length of the preceding recording medium in a transport direction, a timing to stop the rotation of the sidetrack roller such that, when the sidetrack roller is made to start rotating at a predetermined timing to start, a leading edge of a following recording medium transported by the second transport roller becomes aligned with a leading edge of the preceding recording medium, stops the rotation of the sidetrack roller at the determined timing, and transports the preceding recording medium with the following recording medium stacked thereon, to the processing tray, by rotating the second transport roller and the sidetrack roller at the reference timing to start.

There are a paper storage that stores paper on which an image is formed, a paper guide that is movably provided in the paper storage and restricts a position of the stored paper, a paper size acquirer that acquires a size of the paper stored in the paper storage, a size change determiner that determines, by using the acquired size of the paper, whether the paper stored in the paper storage was changed, a confirmation information selector that, when it is determined that the paper stored in the paper storage was changed, selects confirmation information requesting confirmation of a position of the paper guide in the paper storage in accordance with a difference in size between paper before and after the change, and a confirmation information notifier that notifies the selected confirmation information.

A post-processing unit is disposed so as to face the apparatus side surface of a printer that has a manual feed tray protruding from the apparatus side surface. The post-processing unit has an ejection tray, which is movably provided in a unit body and to which paper accepted from the printer is ejected. In an apparatus height direction crossing a direction in which paper is ejected, the ejection tray can be moved to a first position at which ejected paper can be mounted and to a second position at which part of paper mounted on the manual feed tray can be supported.

A sheet processing machine stores sheets transported by a transport unit. The sheet processing machine includes: a reel on which a first end side of a tape is wound; a first stepper motor that rotates the reel about a rotation axis of the reel; a drum configured to wind up a second end side of the tape together with the sheets to form a winding body together with the tape and the sheets; a second stepper motor that rotates the drum about a rotation axis of the drum; and circuitry configured to change an interval between the sheets wound on the drum by controlling a rotation of the first stepper motor and the second stepper motor based on a parameter indicating a condition of the winding body.

According to an example, a method to wind media in an output roller downstream a media advance engine comprises advancing a medium for a determined medium length, collecting a first portion of the determined medium length at a first speed by rotating the output roller in a winding direction, and collecting a second portion of the determined medium length by rotating the output roller in a winding direction at a second speed, wherein the first speed is greater than the second speed.

A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.
