Abstract

A resistive substrate, thermal ribbon is reinked from a replaceable cartridge which moves across the printing area during printing. The cartridge either contains or fits around the ribbon and has a solid ink supply which is melted onto the ribbon from heat generated by a reinking electrode head basically similar to the printing electrode head.

Thermal Printer Re Inking Cartridge

A resistive substrate, thermal ribbon is reinked from a replaceable cartridge which moves across the printing area during printing. The cartridge either contains or fits around the ribbon and has a solid ink supply which is melted onto the ribbon from heat generated by a reinking electrode head basically similar to the printing electrode head.

Fig. 1 shows an embodiment in which the ribbon 1 is an endless band contained in the cartridge 3. A disk 5 of meltable solid ink is also contained in the cartridge, positioned on the printing side of the ribbon. The cartridge has openings in the bottom which fit over and receive a reinking electrode head 7, containing at least a single line of electrodes which supply current. A standard printing electrode head 9 is located where the path of ribbon 1 is at the side of the cartridge adjacent to a standard platen 11 supporting paper 13 to receive the printing.

Printheads 7 and 9 are on an essentially standard carrier 15 which can move laterally across platen 11 to effect printing in lines on paper 13 in the conventional manner. Ribbon 1 is moved counterclockwise. As ribbon 1 passes between the nip of ink disk 5 and head 7, current is driven through the resistive layer of ribbon 1 in a manner essentially the same as printing to create sufficient heat to melt ink from disk 5 and thereby reink ribbon 1.

Fig. 2 shows an alternative embodiment in which the ribbon 1A is permanently stretched acros...
