摘要:
A system and method is disclosed for print media back-feed control for a printer. The invention incorporates use of a downstream sensor to detect at least one of a leading edge of a print media or an indicia correlated to parameters of the print media. The print media can then be back-fed by a controller to accurately position a print line of the print media proximate to a print head of the printer without losing sufficient nip pressure.

A system and method is disclosed for monitoring and determining the amount of ribbon on a supply spool used in a printer. The system and method monitor the rotation of a drive motor to determine a change in useful life that is then used to update the ribbon cartridge useful life that is stored on a ribbon cartridge memory device of the ribbon cartridge. Rotation of the supply spool or take-up spool may be used to estimate the ribbon cartridge useful life when the stored ribbon cartridge useful life is undefined or inaccurate.

An edge guide is described that is adapted to restrict lateral movement of a flexible web as the web advances past the guide, the web comprising top and bottom face surfaces and two lateral edge surfaces, the guide comprising (i) a multi-sided body, and (ii) a cavity in one side of the body, the cavity comprising (a) a curved support surface adapted to receive a first lateral edge and to support a portion of the bottom face surface of the web as the web moves laterally into the cavity of and advances past the guide, and (b) a hard stop above, and in one embodiment, continuous with the curved support surface, the stop adapted to engage the first lateral edge of the web and block any further lateral movement of the web over the curved support surface.

The present invention provides a media guide system for guiding media unwound from a roll of a roll assembly along a direction of roll feeding in a printer. The guide system includes a guide base including a datum edge guide surface and a plurality of edge guide receivers. The datum edge guide surface is aligned along a direction of roll feeding. The plurality of edge guide receivers is formed in the guide base and extends along the direction of roll feeding. When the roll assembly is loaded into the guide base by engaging an edge guide of the roll assembly into at least one of the plurality of edge guide receivers, the datum edge guide surface of the guide base and the edge guide of the roll assembly serve as edge guides to guide the roll through the printer during a printing operation.

A label applicator that prints and applies a label onto an elongated object, such as a wire. The label applicator includes a base assembly having an upper surface. A printer is fixed to the base assembly for printing indicia on a label to form a printed label. A label wrapper is fixed to the base assembly adjacent to the printer for receiving the printed label and an object. In operation, the printer feeds the printed label into the label wrapper to form slack in the label to remove tension from the label prior to the label wrapper wrapping the label onto the object.

A drive train for a printer is disclosed that provides and maintains a desired tension in the ribbon during transfer of the ribbon between a supply spool and a take-up spool. The drive train is configured to pre-tension the ribbon proximate the driven spool prior to driving the drive roller. During operation, the drive train provides and maintains the requisite tension in the ribbon proximate the driven spool with use of a slip-overdrive assembly. Additionally, the drive train induces a drag on the spool from which ribbon is being unwound with the use of a drag-overrun assembly.

A cutting assembly for a printer that includes a cutting frame that has opposing side walls is provided. The cutting assembly further includes a blade housing slidably mounted in the cutting frame for slidable movement along the side walls and a blade fixed in the blade housing that includes a cutting edge. The cutting assembly further includes a plurality of ejector posts that extends from the blade housing in a direction of blade housing slidable movement and past the cutting edge to engage media being cut by the cuffing edge.

A label wrapper block assembly for mounting in a rotatably mounted wrapper frame in a label wrapper assembly includes a base having opposing ends joined by a top surface and a bottom surface. A channel extends between the ends in the top surface for receiving an object being wrapped by the label wrapper assembly. At least one biasing member is extendible into the channel for urging the label against the object received in the channel. In one embodiment, the at least one biasing member is a flexible material stretched across the base top surface.
摘要:
A bidirectional hand held label printer with a novel labeling media and ink ribbon drive mechanism. A delay is introduced in the labeling media and ink ribbon drive mechanism to pretension the ribbon prior to feeding labeling media and ribbon past the print head. When the drive motor reverses direction, the drive roller stalls momentarily while the take up ribbon drive spindle tensions the ribbon in the desired direction.
