The RBT IV tamper evident paper is approximately 36 ft long. The RBT IV prints three consecutive copies of each test for a total length of about 5 1/2″. The operator then cuts the three tests apart to fasten one result to each of the three copies of the Alcohol Test Form. Therefore, one roll of RBT IV Tamper Evident printer paper will yield approximately 75 tests, with a test result fastened to each of the three copies of the Alcohol Test Form.
