摘要： An inkjet printer in which a printhead defines an elongate array of orifices from which jets of ink are projected into a space within which substrates to be printed are presented. An air curtain generator fixed in position relative to the printhead extends along one side only of the array of orifices so as to direct a curtain of air across the array a of orifices and across an open portion of the printhead on the side of the array of orifices remote from the air curtain generator. The air curtain cleans the printhead. A pressure pulse may be applied to ink within the printhead sufficient to discharge ink form each orifice when not in use to project ink. The pressure pulse has a relatively rapidly rising leading edge and a relatively slowly falling edge. An ink reservoir is coupled to the printhead for supplying ink to the orifices. The orifices may be arranged in at least two vertically offset groups, the reservoir being divided into vertically offset reservoir sections including a lowermost section and an upper section with each reservoir section being coupled exclusively to a respective group of orifices. The upper reservoir section is arranged to overflow into the immediately adjacent reservoir section which is spaced therebelow. Each reservoir section includes an ink level detector, and ink is supplied to the reservoir section which is vertically uppermost if any level detector detects an ink level below a predetermined level.

摘要： An apparatus for maintaining an inkjet printer printhead in a working state, the printer defining an array of orifices from which in use jets of ink are projected. The apparatus may have a means for applying a pressure pulse to ink with the printhead sufficient to discharge ink from each orifice when not in use to project ink. The pressure pulse may have a relatively rapidly rising leading edge and a relatively slow falling trailing edge.

摘要： A thermal transfer printer comprises a print head drive mechanism that is configured to reciprocally move a print head parallel to movement of a carrier ribbon past the print head. A controller is configured to control the print head drive mechanism to move the print head in a first direction along the carrier ribbon to transfer ink material from the carrier ribbon to a substrate to print a first portion of an image on a first area of the substrate. The controller is also configured to control movement of the print head in a second direction opposite to the first direction as the carrier ribbon and substrate are also moved in the second direction to position the print head relative to the carrier ribbon so that a second portion of the image is printed on a second are of the substrate adjacent to the first area of the substrate.

摘要： An electrically operated fluid flow valve arrangement (50) includes an electrically powered magnetic field generator (42), a valve body (44) defining a valve chamber (7), an inlet port (5), an outlet port (20) and a valve member (18) located in the chamber (7). The valve member (18) is movable between closed and open conditions relative to one of the ports (5, 20). The valve member (18) includes a permanent magnet (9). The arrangement (50) includes a switchable pole 46 formed of a ferromagnetic material. In use, in a first latched condition, the valve member (18) is retained by the switchable pole (46) in one of the closed or open conditions and, in a second latched condition, in the other of the closed or open conditions, the valve member (18) being moved from one latched condition to the other by operation of the generator (42).

摘要： A tape drive for use in for example a transfer printing apparatus to drive a printer ribbon. The printer ribbon is mounted on two spools each of which is driven by a respective stepper motor. A controller controls the energization of the motor such that the ribbon is transported in at least one direction between spools mounted on the spool support. The controller is operative to energize both motors to drive the spools of ribbon in the direction of ribbon transport to achieve push-pull operations. Ribbon tension is monitored to enable accurate control of ribbon supply and ribbon take-up, the ribbon tension being monitored, for example, by monitoring power supply to the two stepper motors.
