The cooling fan (46) cools the heat sensitive paper carried from the erasing roller (37) to release stored heat in the heat sensitive paper.

The label (1) is made of a heat-sensitive paper having the ability to produce red frank-markings (5-16) at selected locations on the paper.

Thermographic paper for the integrated ChronoProof printer, 57 x 35 mm

The heat sensitive paper is heated by the roller (37) and gradually cooled by the carrying to perform erasure processing for the heat sensitive paper.

Thus, transfer efficiency of heat from a heating part (40) of the resistive element (4) to a heat sensitive medium is improved, and heat sensitive paper can be smoothly transferred.

The print processing part (52) performs print processing for the erasure-processed heat sensitive paper.

The erasure processing part (51) further comprises an erasing roller (37) heating and carrying heat sensitive paper fed from a paper tray (2).

And it can be recorded by high-quality thermal recorder.

We receive a little receipt from her, printed on a thermal-sensitive paper, displaying the exact time: 07h26.

The printing can be accomplished, for example, using a thermo-print head (218) of the electronic reading device in connection with a thermal sensitive paper.

The computer-controlled printing and marking device enables to print any printable material, as well as thermosensitive, electrosensitive and pressure-sensitive paper.

This article tells you how to identify the advantages and disadvantages of thermal paper, so as not to fall into the trap again.

According to the present invention, heat-sensitive paper which is economical and has high storage stability and high reliability with respect to a thermal head can be obtained.

As Professor Sheridan explained, “we could have one student building a computer, another developing three-dimensional photography, a third working with sound transmission, a fourth manipulating heat sensitive papers and so on.” (2)
