A cleaning device cleans a screen mask. The cleaning device includes a cleaning sheet configured to clean the screen mask; a roll-shaped supply section configured to supply the cleaning sheet; a cleaning head configured to press the cleaning sheet supplied from the supply section against a rear surface of the screen mask; a roll-shaped winding section configured to wind a used cleaning sheet; a driving section configured to drive the winding section; a moving mechanism configured to move the supply section, the cleaning head, and the winding section in the same direction as and in an opposite direction to a supply direction of the cleaning sheet; a lifting and lowering mechanism configured to lift and lower the cleaning head; and a brake mechanism configured to allow rotation of the supply section when the cleaning head is lowered by the lifting and lowering mechanism, and to restrict rotation of the supply section when the cleaning head is lifted by the lifting and lowering mechanism.

Screen printer 10 is for screen printing solder paste 13 loaded on an upper surface of stencil 12 onto board S using one of first and second squeegees 71 and 72. Screen printer 10 is provided with a stencil frame holding rail that holds stencil frame 12a of stencil 12, pair of board holding members 36 and 38 that hold board S, raising and lowering table 16 that raises and lowers board holding members 36 and 38, and pair of stencil supporting members 50 and 52 that support stencil 12 from below at a portion outside a printing region of stencil 12 used for screen printing. Stencil supporting members 50 and 52 are provided independently from raising and lowering table 16. Therefore, the load applied to raising and lowering table 16 is reduced. Also, there is increased design freedom with respect to members and the like loaded on raising and lowering table 16.

A screen printer includes: a substrate holder that holds a substrate; a mask to be contacted with the substrate; an imaging device that images the substrate; an elevation mechanism that moves up the substrate holder at a below-mask-position below the mask based on a result of the imaging to contact the substrate with the mask; a horizontal moving mechanism that moves the substrate holder between the below-mask-position and a retreat position retreated in a horizontal direction from the below-mask-position; a printing head that moves on the mask contacted with the substrate and prints a paste on the substrate via the mask; and a mask cleaner that cleans a lower surface of the mask with the substrate separated from the mask by the elevation mechanism. The imaging of the substrate and the cleaning of the mask are performed with the substrate holder positioned at the retreat position.

A wiping device includes a windable web and a blade, and wipes out a nozzle surface provided on a liquid discharge head and including a plurality of nozzle holes. The wiping device wipes out the nozzle surface by at least the web when there is a remaining amount of the web, and wipes out the nozzle surface by the blade when there is not the remaining amount of the web.

A printing system cleaning fabric (13), having a first layer (131) with a first cleaning surface (131), and a second layer (132) with a second cleaning surface (1321) facing away therefrom. The first and second layers (131, 132) extend parallel to each other and have a respective inner surface (131, 132) attached to the other along an extension of the cleaning fabric (13). The first and second layers (131, 132) have different permeability characteristics.

A maintenance unit is provided to be mounted on a liquid discharge apparatus including a discharge portion that performs printing by discharging a liquid from a nozzle to a medium when the printing is not performed, and includes a cap configured to form a space in which the nozzle is open, and a pump configured to depressurize the space.

A stencil printer includes a stencil, a material applicator to apply material on the stencil, and a stencil wiper assembly to selectively wipe the stencil. The stencil wiper assembly includes has a quick-change material module having a supply roller to receive a roll of material, a take-up roller to receive used material, a drive to move the material across the stencil from the supply roller to the take-up roller, and a controllable tension device configured to vary a tension of the material when driving the material from the supply roller to the take-up roller.

A removable flexible jacket for use in a printing press having a transfer cylinder for transferring a freshly printed substrate comprises a sheet of woven fabric, a beaded film sheet coupled to the sheet of woven fabric, and an image disposed between the sheet of woven fabric and the beaded film sheet. The image is visible through the beaded film sheet, and wherein the image divides at least a portion of a surface of the beaded film sheet into a plurality of zones.

A coating unit is located after a sheet-fed digital printer on a manufacturing line. As a response to a workpiece entering the coating unit from the printer, coating substance is dosed onto a plate cylinder, and said plate cylinder is rotated to transfer said coating substance onto the workpiece, which is then transferred further on the manufacturing line. As a response to a first time limit expiring after transferring the workpiece further without a subsequent workpiece entering the coating unit, the rotation of the plate cylinder is stopped.

A recording apparatus includes a recording unit; a wiping unit configured to wipe the discharge port surface; at least one memory storing instructions; and at least one processor that is in communication with the at least one memory and that, when executing the instructions, cooperates with the at least one memory to perform control to cause the wiping unit to perform a wiping operation for wiping the discharge port surface, and then cause the wiping unit to feed the wiping member to enable wiping with a new region of the wiping member in a next wiping operation, acquire information about a discharge amount for each discharge port array, and determine a feed amount for feeding the wiping member after the wiping operation, based on the information about the discharge amount.
