  • Patent number: 7037012
    Abstract: A scanning system for use in inspecting or writing on a substrate minimizes vibrations by applying movement-actuating forces directly between a carriage and a countermass which are both free to move along parallel tracks. Forces for decelerating and accelerating the scanning carriage are preferably applied along a minor part of a length of movement of the carriage. The carriage is then isolated from forces applied parallel to the track while moving along a major part of its length of movement. As a result, the carriage travels smoothly with approximately uniform speed during it's operative pass, without suffering from vibrations introduced by direct closed-loop feedback control.

  • Patent number: 6634815
    Abstract: The present invention pertains to the field of ink-jet printers used for color printing of large format articles This invention is used for improving quality and for increasing the yield of printers and comprises successively applying primary colors, suppressing color aberrations when printing a semi-transparent material on both sides, precisely positioning the head when printing an image on the substrate and eliminating the lines connecting the carriage to the systems supplying control signals, air and inks. To this end, the carriage with the jet heads is moved in one direction along a closed guiding rail which is fitted with a hatched ruler for precise positioning, wherein the heads will thus bypass the substrate on both sides while information is transmitted from the device control unit to the carriage using a radio transceiver. The printer can further be equipped with two independent and parallel substrate feeding systems for performing a one-sided printing on two substrates at the same time.

  • Patent number: 6616354
    Abstract: Apparatus for adjusting the spacing in a printer between a printhead and the travel path for print media which moves through the printer. The printhead is borne by a carriage which is rotatably mounted adjacent an elongate bearing rail wherein the rotated condition of the carriage relative to that rail establishes the desired spacing. First and second relative moveable bearing structures mounted on the carriage include bearing surfaces which can alternatively adjust the bearing structures so that one or the other, but not both, determine the rotated condition of the carriage.

  • Patent number: 6616360
    Abstract: Disclosed herein is cutting assembly for use with a label printer. The cutting assembly includes: a cutting assembly frame; a plotter cutter for plotter cutting a label media, the plotter cutter connected to the cutting assembly frame; an end cutter for end cutting the label media, the end cutter connected to the cutting assembly frame; and a drive mechanism connected to the plotter cutter and the end cutter. During end cutting, the plotter cutter is coupled to the end cutter such that both the plotter cutter and end cutter are driven by the drive mechanism. During plotter cutting, the plotter cutter is uncoupled from the end cutter such that only the plotter cutter is driven by the drive mechanism.

  • Patent number: 6602005
    Abstract: An assembly including a carriage for driving a marking apparatus on at least one guide member wherein the carriage is secured to a bearing allowing the carriage to slide on the guide member. The carriage includes at least one opening made with transverse dimensions substantially greater than those of the guide member so that when the carriage is placed in position, an intermediate space is defined between the walls of the opening and an opposite outer periphery of the guide member which space is filled with a polymerizable resin which forms a bearing sleeve between the walls of the opening and at least a part of the outer periphery of the guide member.

  • Patent number: 6575646
    Abstract: A printer carriage has a bushing liner arranged to slide on a rod, the liner including a metal body with plastic inserts having, on their inside surfaces, ribs, which constitute the bearings of the bushing liner. The inserts are located in grooves of the metallic body by means of an injection moulding process. The external surface of the bushing liner comprises a plurality of flat and curved sections arranged asymmetrically to permit firm and accurate location in an aperture of the carriage.

  • Publication number: 20020146268
    Abstract: A printhead carrier assembly in an ink jet printer includes a carrier moving along a linear path. At least one rotatable bearing is attached to the carrier. The at least one rotatable bearing has at least one axis of rotation. A rotatable shaft has a surface in contact with the at least one bearing such that the shaft is nonparallel to the at least one axis of rotation of the at least one rotatable bearing. The shaft is substantially parallel to the linear path of the carrier. Rotation of the shaft causes the at least one rotatable bearing to roll along a helical path on the surface of the shaft to thereby carry the carrier along the linear path.

  • Patent number: 6461064
    Abstract: This invention relates to an improved wide format color digital print engine, and in particular to a drum-based large format digital ink jet print engine having a vertically articulated carriage portion which carries both the print heads and an imaging array, adjustable saber angles for print heads, a novel service station, and an extremely robust weight-bearing carriage architecture. In particular, the present invention provides a highly manufacturable print engine benefiting from a discrete few controlled mounting locations so that accurate mounting of the cooperating sub-assemblies allow a very stable carriage assembly for driving said carriage laterally with respect to a printing medium coupled to the exterior of a drum.

  • Publication number: 20020110398
    Abstract: A carriage assembly of a printer employing a movable print head is disclosed. In the carriage assembly, bosses provided with respective bearing supporting holes each inner circumferential surface of which has a predetermined radius of curvature are formed at a side of a carriage, and bearing bushings each of which has an outer circumferential surface having a different predetermined radius of curvature corresponding to that of the bearing supporting hole, and makes a spherical pair with the bearing supporting hole. A shaft through-hole through which a guiding rod is inserted slidably is formed through each bearing bush. The bearing bushing can rotate freely in the bearing supporting hole, and therefore, the axes of the carriage assembly and the guiding rod can be aligned automatically.
