how thermal fax machines work

Meltdown: thermal transfer fax machine while thermal paper is still useful for hot printers for receipts and barcodes, a different thermal method has replaced [1] for most modern hot fax machines [source: Sems].
Given that thermal paper allows heat to be applied directly to paper, the thermal transfer method uses a third reagent between the heating element print head and the paper.
This middleman is a ribbon containing the necessary \"ink.
\"However, it is still considered a hot fax machine because it requires heat to transfer the ink of the ribbon to paper.
Unlike the direct method, you do not have to purchase special paper for the heat transfer machine;
This machine can be replaced with ordinary paper.
However, the basic techniques used by the print head are roughly the same as those printed on thermal paper.
The print head provides heat to the heat transfer tape in place and melts these areas.
This melting process allows the ribbon to release the ink it contains onto paper delivered through the machine.
The ribbon itself can be composed of a base film made of materials such as polyester and attached to the base film, which is a substance that constitutes ink [

Another layer of protective coating prevents it from sticking to the print head.
The ink layer is usually made up of one of three materials: therefore, in the heat transfer method, the print head receives coded information about when and where to heat, as in the direct heat method.
This time, however, the ribbon extends along between the paper and the print head.
When the print head heats the ink material of the ribbon, it releases the ink and the ink melts on the paper.
Understanding the thermal methods of these fax machines can give us an idea of their advantages, which we will discuss on the next page.
