Selective Oil Transfer Printer

In this printer, oil is selectively transferred to a paper to form characters. The paper is then passed through a xerographic-type toner and fuser to make a permanent image.

In the drawing, a strip of paper 1, which may have conventional carbon sheets 2 associated with it, passes over a guide roll 3 and between a line of selectively actuated wires 4 and an ink drum 5. The drum 5 is coated with a thin film of oil by the roll 6 which is in contact with an oil reservoir 7. The wires 4 are heated by a common source 8 (shown as a coil of resistance wire) and are individually actuated (by means not shown) to form characters on the moving paper 1. Normally, oil will not pass from drum 5 to the paper 1. However, the combination of impact and heat will cause a transfer of oil from drum 5 to paper 1 to form an oil spot on the paper. The paper 1 is then moved from drum 5 over roll 9 and through a finely divided toner reservoir 10, where the toner will stick to the oil spots only. The carbon papers 2 will be separated from paper 1 at roll 9 and may be guided by a roll 11 to a discharge area.

After passing through toner reservoir 10, the paper 1 passes over a roll 12 and through a fuser station 13, where heat is applied to melt the toner sticking to the oil spots and make the image permanent. The paper may then be sent to a discharge station for further processing, as required.

It is also possible to transfer the oil as a vapor from reservoir 7...
