GENERAL DESCRIPTION OF A FACSIMILE
2.2
Recording Section
This is the so-called printer.
Here, picture data that is sent from the other party is printed on paper.
Generally, the following three methods are used for recording on a facsim-
ile.
2.2.1 Thermal recording method
This recording method uses paper (heat-sensitive paper) that has been
coated with a color-forming layer. Color is formed on this paper by the
action of heat on its surface. Heat is generated by a thermal element (ther-
mal head) that is held in contact against the surface of the color-forming
layer.
This recording method has a drawback in that it is not suitable to long peri-
ods of storage as heat-sensitive paper fades with time. However, it has the
advantages that facsimiles can be made compact due to its simple structure
and is maintenance-free. For these reasons, it is the most widely used of
the recording methods in entry facsimile models such as facsimiles for
household use.
