ABSTRACT:
A paper transport system used in connection with a thermal analog recorder is provided. This system engages the paper for a predetermined length of time and subsequently releases it employing mechanical means. Roller means are provided for engaging and transporting a heat sensitive paper. When the test paper is inserted into the nip formed between the roller means, a tapered resistor element residing on at least one of the rollers is made to develop a non-uniform temperature profile when energized from the output of a test source which permanently marks or records on the test paper. An improved method of single channel thermal analog recording is also disclosed employing this device.
