Filed:

Jul 12, 2001

Appl. No.:

09/904249

Inventors:

David L. Poole - Palatine IL
Barry R. Knott - Wheeling IL
David Laurence George Worgan - Crewe, GB

Assignee:

Zih Corporation - Wilmington DE

International Classification:

G01D 1516

US Classification:

347213

Abstract:

A thermal printer that includes a thermally conductive sacrificial member disposed between the thermal print head and the web. The sacrificial member is held generally under tension and prevents the web from directly engaging the thermal print head. The sacrificial member may take one of many different forms, including a fixed strip or belt, a rotatable, continuous belt which slowly recirculates during printing to equalize wear across its surface, or a Moebius loop which further provides that wear is equalized across both sides of the belt. By providing a sacrificial member between the print head and web, wear and exposure of the print head is reduced, thereby prolonging the life of the print head.

Assignee:

ZIH Corp. - Hamilton

International Classification:

B41J 3528

US Classification:

400207, 400234

Abstract:

A ribbon cartridge for a thermal transfer printer is configured to provide a retractable feed for a donor ribbon. The ribbon cartridge includes a housing, a roll of donor ribbon wound on a core within the housing, and a clutch operatively coupled to the core. A resilient structure is coupled to the clutch and to the cartridge housing such that the release of energy stored in the resilient structure by advance of the donor ribbon produces retraction of ribbon slack, if the donor ribbon is released or backfed. Alternatively, a ribbon roll having a self-contained clutching and slack take-up capability includes a hollow core configured to receive a roll of ribbon and a clutch having a friction component configured to induce frictional engagement with the core. At least one end of the clutch is adapted to be externally constrained, and a resilient component is located between the friction component and at least one end of the clutch.

US Classification:

358 19, 358 12, 358 15, 358 309

Abstract:

Ethernet and Universal Serial Bus (USB) powered printing devices are provided. In particular, Ethernet and USB powered printers and methods of Ethernet powering of printers that support high speed printing and/or data intensive printing. Such high-speed and/or data intensive printing operations are able to be Ethernet or USB powered by providing for a power storage unit within the printer device that is able be charged during non-printing periods and provide for necessary energy bursts to support such higher powered processes. In addition, the present invention provides for devices and methods that allow for printers to operate with main power provided by conventional power mains and for back-up or secondary power to be supplied by Ethernet or USB power. Additionally, the invention provides for Ethernet or USB powering, both primary and back-up, of the data and configuration settings in the printer control and image generating electronics. In the back-up power mode, the Ethernet or USB power insures that data and configurations are not lost during periods of main power outage.

International Classification:

B65H016/04

US Classification:

242597600

Abstract:

A media centering spindle assembly with a spindle body and a clutch drive assembly. The spindle body includes a centering mechanism such as a rack and pinion or centering slat. The centering mechanism is configured to center and retain a media roll, ribbon supply or the like along the spindle body and includes at least one spring tab. The spring tab is deflectable from an initial position to a second position below a surface of the spindle body to allow the mounting of the media roll or the like. The assembly may be further configured as rotatable about a longitudinal axis of the spindle body with the clutch drive assembly having a friction level adjustable by rotation of a clutch adjuster about the longitudinal axis of the spindle body.

US Classification:

400 88

Abstract:

A thermal hand-held printer applicator is disclosed preferably having a roller for gripping the work, a governor for limiting the speed of the roller and thereby the speed of motion of the printer applicator over the work, a tachometer for measuring the roller speed, a print head for printing an image on one of a thermally sensitive web of self adhesive labels, drive means for advancing the web and ejecting one label onto the work, and smoothing means for applying the label to the work.

International Classification:

B41J 3336

US Classification:

400232

Abstract:

A thermal transfer printer includes an arrangement for continuously and automatically varying the rate of advance of the thermal transfer ribbon during printing, the rate of advance being correlated with the nature of the image being printed, and the variable advance rate being provided by a driven friction feed roller and a pair of ribbon guides which cooperate with the friction feed roller and are so positioned that the transfer ribbon is held tightly against the friction feed roller, contacting the circumference of the friction feed roller over more than 90. degree. its circumference and preferably at least 180. degree. of its circumference.

Abstract:

A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer.
