How often should processor transport times be tested?

• A. Daily
• B. Weekly
• C. Monthly
• D. Annually

Answer: (D)

The main idea here is scheduling QA checks for a film processor’s transport mechanism. Transport time—the speed at which films move through the processor—is a mechanical parameter that tends to stay consistent over time unless wear or a fault develops. Because of that stability, you don’t need to recheck it every day or even every week; daily checks focus on streaming variables like developer temperature and chemical levels, while monthly checks cover broader processor performance.

An annual verification provides a solid baseline measurement and lets maintenance staff confirm that the transport system remains within spec over the long term. If a problem appears, it can be investigated and corrected during the annual preventive maintenance window, without interrupting daily workflow. So, testing transport time annually best balances reliability with practicality.
