Siemens has been receiving complaints having to do with film path within the Dimension Instrument Series. Siemens links this to a variation in tension of the film.
The film is used to create cuvettes used for medical analysis. This film is packaged in a canister (right) assembly that is held in place with a brake spring, and pulled out by a motor at the end of the cuvette path way.

Develop a better testing system that identifies the issues associated with the Dimension Instruments in order to reduce customer complaints and improve the quality control of the film canisters.
Design for Film Path
The tester will be returned to Siemens for further analysis. After Siemens performs their series of test, the belt will be passed off to Nypro. The tester will be configured with a belt for accelerated wear. Nypro will perform quality control tests on the manufactured canister. This will help avoid canisters that don’t remain within the desired limits of 180 to 700 gram-force.
