摘要： A printing apparatus comprises a first roller for conveying sheets, a first motor for driving the first roller, a second roller for conveying sheets, and a second motor for driving the second roller, and a conveyance controller that controls conveyance to be able to execute a first conveyance operation for conveying sheets such that the trailing edge of a preceding sheet and the leading edge of a succeeding sheet overlap, and a second conveyance operation for conveying sheets by arranging a distance between the trailing edge of the preceding sheet and the leading edge of the succeeding sheet, wherein the conveyance controller, based on information indicating that the second motor is in a temperature rising state, controls whether to execute the first conveyance operation or to execute the second conveyance operation.

摘要： An example apparatus includes a processor and a memory in which is stored machine-readable instructions that are executable by the processor. The instructions cause the processor to determine a first operating torque response of a motor during a first operation of the apparatus, determine a second operating torque response of the motor during a second operation of the apparatus, the second operation being different from the first process, and determine an amount of media present in a media bin based on the first operating torque response and the second operating torque response.

摘要： A media feed appliance can include a media pull guide to guide a print medium through a path while the print medium is manually pulled through the media feed appliance. The media feed appliance can also include a drive gear that is manually driven using frictional contact with the print medium while the print medium is pulled over a surface of the drive gear. The media feed appliance can also include a printer positioning port to position a manually actuatable printer to print on the print medium, wherein the drive gear of the media feed appliance is positioned to mechanically engage with a printer gear when the manually actuatable printer is docked at the port.

摘要： A method is disclosed for reducing the scatter of UV light during a final curing operation in the three-dimensional printing on the surface of transparent and semi-transparent media. The method precisely controls the movement of media during a final cure step in the printing of an expressed inkjet image on the surface of transparent media. The method also controls a number of factors during final curing operation such as the lateral movement of media under a final cure lamp, the number of rotations that media undergoes during final curing, the timely modulation of UV lamp power during final curing, and the selection of UV emitter segments positioned away from a inkjet print head to reduce the amount of potential UV radiation from impinging upon one or more of the adjacent printing heads.

摘要： A recording device as a processing device includes: a recording unit accommodated in a housing and configured to perform recording on a medium; and a medium accommodating unit that accommodates the medium discharged from the housing. The medium accommodating unit includes: a sheet-shaped accommodating member; a rotating shaft provided inside the housing and to which one end of the accommodating member is connected; and an operating portion provided separably from the housing and to which the other end of the accommodating member is connected. The accommodating member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing. The accommodating member is fed from the rotating shaft so that the medium is accommodated when the operating portion is separated from the housing.

摘要： A method for automated alignment and register measurement in a printing press provides for test patterns having multiple color separations to be printed by the printing press on a printing substrate, recorded by using at least one image sensor of an image acquisition system as a digital overall image, evaluated by a computer with respect to an alignment/register offset and then corrected by the computer for the alignment/register offset. Circular measuring marks having known diameter for each color separation are integrated into the test patterns and the computer ascertains the center position of each circular measuring mark with subpixel accuracy and thus computes the alignment/register offset by cutting out an image region having at least one circular measuring mark from the digital overall image and determining parameters of a model of a printing point of the circular measuring mark from the digital overall image.

摘要： A conveying device includes a controller configured to control conveyance of a workpiece. The controller includes a first calculator configured to calculate a first roll estimated radius of a first roll varied as a first support shaft rotates. The controller further includes a second calculator configured to calculate a second roll estimated radius of a second roll varied as a second support shaft rotates. The controller also includes a first support shaft drive controller configured to cause a first support shaft driving motor to rotary drive at a first angular velocity according to the first roll estimated radius. The controller further includes a second support shaft drive controller configured to cause a second support shaft driving motor to rotary drive at a second angular velocity according to the second roll estimated radius.

摘要： An image forming apparatus is provided. The image forming apparatus includes a print engine to form an image on a sheet, a feeding apparatus to pick up a sheet loaded onto a knock-up plate and feed the picked-up sheet to the print engine by using a pick-up roller, a feed roller, and a registration roller, and a processor to, based on a print data being received, control the print engine and the feeding apparatus and allow the received print data to be printed. The processor may variably control a feeding speed of the feed roller and allow the picked-up sheet is conveyed to the registration roller within a predetermined time.
