Regarding daily checks of film washing time, which statements are true?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (B)

Consistent wash time is essential to remove fixer residues from the film emulsion and prevent processing artifacts. Daily checks keep the washing stage aligned with the processor’s specified time under actual operating conditions (water temperature, flow, agitation, and overall performance). By verifying the actual wash time against the standard every day, you catch drift in the system and ensure that the fixer is being removed adequately. The best choice reflects both the need for daily verification and adherence to the target washing time; it’s not correct to skip daily checks or to claim wash time isn’t important. In practice, you’d compare the measured wash time to the specified value and take action if it’s out of tolerance.
