Abstract: In an image forming apparatus having a document feeder for taking up a document from a document bundle placed on a document tray, a controller has a normal mode to perform a normal-size conveyance control by taking up each document from a bundle of documents having the same size, a multi-size mode to perform a multi-size conveyance control by taking up each document from a bundle of documents having various sizes. When the normal mode is carried out, the controller controls to stop the document after the first preset time passes after the trailing edge of the document has been detected, and when multi-size mode is carried out, the controller controls in place of using the first preset time by the second preset time which is set to be a longer time than the first preset time.

Abstract: A printing unit contains at least one printing group which is comprised of at least two cylinders which cooperate to form a printing nip. At least these two cylinders are interconnected in a positive fit by a drive. The two cylinders can be engaged with one another in a first position (ON), or disengaged from one another in a second position (OFF). The two cylinders can also be disengaged from each other at a spacing distance in a third position (STOP). That spacing distance is sufficient to allow a web in the printing operation to be guided between the two cylinders without making contact with the two cylinders.

Abstract: A method of printing design seamlessly on clothing, and clothing obtained thereby are provided. The method includes steps of placing a cylindrical cover around a print cylinder, placing a print medium, on which a design is printed, around the cylindrical cover, placing a cloth around print medium, and heating the print medium so that the print medium and the cloth are heated and the design is transferred from the print medium to the cloth. The transfer of the design is done by sublimation of dye, which forms the design, induced by the step of heating. The cloth is subsequently cooled and flipped.

The manual repetition system (MRS) has an MRS frame mountable to the screen frame, a track system, and a height adjustor configured to adjust the height of the track system relative to the MRS frame. A squeegee has a squeegee frame with a blade, guide members configured to guide the squeegee through the track system, and an angle adjustor configured to adjust the angle of the blade relative to the screen mesh during operation.

Abstract: A method and device for moving media sheets along a media path. In one embodiment, the media path comprises a metering nip, at least one transfer nip downstream from the metering nip, and a feed nip upstream from the metering nip. The feed nip moves the media sheet initially at a faster speed than the metering nip. This speed variation causes a buckle to form in the media sheet that aligns the leading edge. The media sheet is then moved from the metering nip into the transfer nip. The metering nip may move the media sheet at a faster speed than the transfer nip again forming a buckle in the media sheet. As the media sheet is moved through the transfer nip, it is tacked to a transfer belt such that it moves consistently through the remaining downstream transfer nips.

Abstract: A transfer device for transferring an object to be transferred in a predetermined direction has a drive mechanism unit, a transfer direction displacement information acquiring unit, a skew direction displacement information acquiring unit, and a transfer processing unit. The drive mechanism unit also has roll parts which cause the object to be transferred to move in the direction with a rotational force. The transfer direction displacement information acquiring unit and the skew direction displacement information acquiring unit radiate a predetermined measuring wave toward the object, so that the units acquire the displacement information in each of the directions. Based on the displacement information, the transfer processing unit performs a predetermined processing.

Abstract: The plate-making printing press is constructed by installing a plate-making apparatus in a printing press that supplies ink and dampening water to a printing plate and performs printing on a medium. In order to realize a high-precision plate-making operation, the printing press is equipped with a target disposed on the printing cylinder and a sensor for detecting the target and provided on the writing device, and the zero point of the encoder is corrected. Furthermore, at the time of plate-making, the adjustment mechanism is operated so that the printing cylinder is returned to the position of the point of origin.

Abstract: The present invention relates to a cartridge for use with a digital printing device. The cartridge includes a casing for housing print media and a supply of ink. The casing also includes a transport assembly which is adapted to cooperate with a powered gear provided on the printing device to thereby eject the print media from the casing.

Abstract: In a laser printer capable of printing on both sides of a sheet, alignment or skew of the sheet is corrected with register rollers before printing is performed first on a side of the sheet. The sheet with an image having been formed by a process unit is fed to a re-circulation path for printing on the other side of the sheet. The sheet alignment or skew is corrected in the re-circulation path by a guide plate while the sheet is fed by re-circulation feed rollers. The sheet fed back to the register rollers is fed toward the process unit without being temporarily stopped at the register rollers before printing on the other side of the sheet.

Abstract: When operating in a photocopier mode a first tray is first selected, and a second tray is then selected if there is no recording medium in the first tray. If recording medium is in the second tray but the size of the recording medium is not the same as the size of the recording medium loaded to the first tray, a notice indicating a size change is presented and recording is completed only if the user approves the size change using an operating panel.

Abstract: Page numbers on original document volumes that have been read are deleted from the read image information as a part of image processing, and page information sorted with the original document pages of multiple read original document volumes as a single document is superimposed onto the image information from which the page numbers have been deleted, following which the pages are printed out. The pages are thus provided with serial page numbers according to the sorting thereof, and situations wherein both original and new page numbers are present on the pages can be avoided.
