Problems solved by technology

Ionic and nonionic antistatic materials are limited by high cost and imprecise use depending on the receiving medium affected by the reduction of electrostatic charge
Another disadvantage associated with non-ionic antistatic materials is the addition of unwanted color in the white areas of the print

Embodiment Construction

[0020] figure 1 An example embodiment of the printer 18 of the present invention is shown. Such as figure 1 As shown in , the printer 18 has a controller 20 that causes a thermal printhead 22 to record an image on a receiver conveyor 26 by applying heat and pressure to transport material from a supply conveyor 30 to a receiver conveyor 26 . Controller 20 may include, but is not limited to, a programmable digital computer, a programmable microprocessor, a programmable logic controller, a series of electronic circuits, a series of electronic circuits reduced to the form of an integrated circuit, or a series of discrete components. exist figure 1 In the embodiment, controller 20 also controls receiving conveyor belt accepting roller 42 (receiver web take-up roller), receiving conveyor belt supply roller 44 (receiver web supply roller), supplying conveyor belt accepting roller 48 (donor web take-up roller) and Supply Conveyor Supply Rollers 50 (receiver web supply rollers); eac...

Abstract

A thermal printer having reduced electrical charge built at point of separation of a donor web and a receiver web, includes at least one thermal printhead and at least one platen roller with a nip is formed between the at least one thermal printhead and the at least one platen roller through which the donor web and the receiver web are drawn. A heat sink is attached to the at least one thermal printhead and a peel member is located downstream of the nip. The peel member is substantially electrically isolated from ground.

Description

technical field [0001] The present invention relates to a thermal printer of the type that applies material from a donor web to a receiver web to form an image on the receiver web. Background technique [0002] In thermal printing, it is well known to produce an image by applying heat to one or more supplied materials (eg, dyes, colorants, or other coatings) and pressing them against a receiving conveyor. The donor material is provided in size-sorted donor patches onto a movable conveyor belt called a donor ribbon. The donor blocks are organized into donor sets on the ribbon; each set contains all the donor blocks used to record the image on the receiving conveyor. For full-color images, multiple color dye patches can be used, such as yellow, magenta, and cyan supply dye patches. Arrangements of other color patches within a supply group can be used in a similar manner. Additionally, each supply set may include a coating layer or a sealant layer. [0003] Thermal printers...
