Appl. No.:

09/883298

Inventors:

Garry Emge - Keene NH, US

David Georgis - Dublin NH, US
James McCann - Marlow NH, US

International Classification:

B41J002/435
B41J015/14
B41J027/00

US Classification:

347/248000, 347/241000

Abstract:

A technique for marking pixels on workpieces by routing a scanned beam to different marking stations to mark individual pixels on the workpieces. A diffractive scan lens focuses the beam. A mark is formed on a workpiece by producing the mark and curing the mark. Angular position of a scanning mirror in a raster scanner is determined by moving a beam, reflected from the scanner, across rulings on an optical element during scanning. A print head for printing spots on a surface of a workpiece has a walled, internally pressurized chamber and structure for causing an inked web to conform to a contour of the chamber wall and to be pulled along the chamber wall. A print head has a compliant-walled, internally pressurized chamber. A print head has a chamber having a low-coefficient of friction coating. Two workpieces may be marked at two marking stations by two-directional scanning.

International Classification:

B41J 33/16

US Classification:

400234

Abstract:

Systems and techniques relating to printing include an apparatus including a base mounting a storage spool to store printing ribbon including a web carrying marking medium, the base mounting a ribbon take-up spool. A ribbon path from the storage to the take-up spool runs through a printing station where there is a print head, and printing is effected at the printing station when relatively moving the head and the substrate with the ribbon interposed between. The apparatus includes a movable ribbon guide member, a ribbon guide member drive device to move the ribbon guide member, and a controller which, during or in between at least some printing operations, controls drive of at least the take-up spool to advance ribbon through the printing station. The controller controls the ribbon guide member in response to an input signal representative of ribbon tension along the ribbon path to adjust the ribbon tension.
