An RPI document. In today's quest to maximize life cycles and increase profits, one would think preventive maintenance would be the gospel. If you travel from doctor's office to doctor's office as most service technicians do, you know this is not so. I often wonder why doctors and dentists spend so much money on equipment and so little time caring for it. After a period of time, rollers have a tendency to swell because of the solution in which they operate.
Rollers also swell if they become overheated.
What's more, overheating will decrease the life of the solution. Foreign material and silver build-up or a slick roller surface also will cause film slippage. If the roller surfaces do not match, film will not move through them correctly. Since intra-oral film is smaller than panoramic or cephalometric, it has less roller contact and more potential for slippage. Following is my recipe for success when it comes to a P.M. schedule for the film processor.
